Derek my father passed away a couple of days ago from cancer he was a big fan of yours and also love watching vise grip garage he always say you catch phrases and stuff that you always say on your videos So thank you for entertaining my father over the years when he was a subscriber/watcher
@@tonyriehle6657 I don't know if I would ever come to grips but I have to be there for my mom and also keep my promise by fixing his late '90s Chevy suburban and his 82 Chevy pickup truck
I was a Cadillac tech during the '80s. I don't miss working on those rolling nightmares. To clear codes, pull the ECM BATT fuse for 15 seconds. Don't worry about those dents in the tire sidewalls, it's just where the cord plys are joined.
I was 14 when a good friend’s mom got one in 1980 around thanksgiving. The family owned a Buick franchise by Christmas it had been towed back to Cadillac a couple of times. By new years she had a 1981 Buick park avenue.
My neighbor had one of those and didn't seem to have too many problems with it, but she inherited it from her Father when he passed, so maybe it had all of the fixes by then. I drove it a few times and have to say it rode like a, well, Cadillac. Nothing like it. If they made a new one just like it today with a reliable drivetrain I'd be in on one for sure. If I ever find one of these old ones in decent shape I'd grab it and see about updating the power plant. I'm getting old and while I like my noisy supercharged F150 Harley Edition, I could go for a silent ride on the clouds from time to time.
Have an in-law who repairs old ECMs. Bottom line, the capacitors leak and dissolve traces on the circuit board. They just recap these things, neutralize any capacitor acid with baking soda, and call them remanufactured. 😂 Anything with EFI which was made in the 1990s or earlier is on borrowed time. Early 2000s ECMs are apparently seeing more failures too. Niche business I guess?
LOL Yes it was the winter hat delete option (think it was option code GMSFU) or you could make fun decorative patterns on the ceiling with thumbtacks in order to keep it up like I did on my 79 Cutlass.
The standard of the world. GM slogan for Cadillac Fleetwood and DeVille. Headliners on both cars were crap and they were not easy to repair or replace.
Your reaction when it fired was pure and real! We can tell that you had absolutely zero expectations that this turd was ever going to fire or run! Excellent.
That’s what I thought, the unmitigated glee that it worked is one reason this channel is so …real for lack of a better term And it puts a smile on a fellas face every time
My grandfather was a Cadillac master and worked for Sewell Village for 27 years. He retired in '89 and unfortunately, we lost him in 2001. He'd love this series and would probably be cussing that design. :D
Late 80's I was a GM technician. Roger Garner Chevy. Cadillac wiring specialist. Drivability and engine rebuild. Those were Good challenges!!! Thank you for sharing this beast of a car. I owned an 8,6,4. Loved it !!!
From 1990 to 2000, I was the Union Representative at Don Rosen Cadillac, just outside of Philly. In 2000 they sold the Franchise back to GM, as part of GM Project 2000. They had 4 Cadillac Master Craftsman who worked there and they were the Best Cadillac Flat Rate Technicians, I ever saw during my 47 years in the Automotive Mechanic Profession. Love the channel, it warms my old retired Mechanic heart.
I worked as a driveability technician at a gm dealership back in the late 80s until mid 2000s. Cadillac was the worst to work on. Gm had software updates for every car to address multiple running issues, so you had to order a new prom, then install it when it came in. Once gm switched to EEPROM systems, it was way easier. We simply downloaded new updates thru the tech1 terminal and uodate using the OBD1 port. Also, code 12 is used as a self check for the ecm, it always states no tach signal as the engine is off during code check. Codes can be erased by simply disconnecting the battery for at least one minute. Also, after it cycles thru 3 read cycles, you you can erase the codes by pressing off and hi. Once it reads 00, codes are cleared
In 1993 I had a 84 Cutlass Ciera Brougham. Tech at dealership in Quaker-town PA was mad I wanted to replace OBDI PROM that was causing Check Engine light to come on. I was stubborn young punk who wouldn't listen to him and wanted to keep the car in original condition. I was a purist who didn't want to drive Cutlass with Check Engine light on. I was an old school car ethusiast whose motto was "if you can't do it right , don't do it all." All I care about is winning. If it costs $5000 or more to fix a problem I don't care. If the car can't run without the Check Engine light I'll junk the f**king thing. Even if I lose thousands of dollars. It's like getting rid of a whore who's outlived her usefulness. Snowflakes. Cry me a f** king river. Man up or junk it the ho or the car.
"Cadillacs are the worst to work on" then you go on to describe the built in diagnostics from 1981 that other kinds of cars still don't have today, over 40 years later. Diagnostics that involve pushing a couple buttons on the dash to get codes and even cycle the 8/6/4.. ahead of its time. Why don't you try to diagnose those '80s L Jetronic systems on German cars.. 😀 I was also a mechanic back then, and I'll take pushing OFF and WARMER any day over counting VOM needle swings on a Ford. Chrysler was also notably easy for back then, IIRC starting in '83 you could just cycle the key three times in five seconds to get codes out of the Check Engine light. I'm glad the '80s are over in terms of how they made cars. Yes, all of them.
@@Bolton115 yes, I worked on Ford's and imports too, still have my breakout box somewhere for the ford eec-4 system, and yeah, did several k-jetronic fuel systems, and I agree, modern computer systems are easier to diagnose the problem. My comment was on the Cadillacs they wanted you to use the onboard diagnostics, where the tech1 scanner was much faster to use, instead of all the sub menus you had to go thru on the Cadillac.
Cadillac provided on board diagnostics because no one had a Tech One, Snap-On 3000 (IIRC) or other cartridge based scan tools yet. The ALDL reader in 1983 was a Sun Interrogator that was the size of a console television and had a box of floppy disks and adapters for various '80s cars. In 1987, my high school auto mechanics class went on a field trip to the VoTech college and they had one. It was pretty impressive for its time. I still maintain that Cadillac were pioneers in this area. No other cars had the computer control and self diagnostics for several years yet -even other GM models-and being able to troubleshoot it with its own dashboard display and a manual is something I still can't do with most 20 years later models. Ok, well now that they all have great big screens and you're more IT guy than auto mechanic.. now you can.
@@Bolton115 I remember that on some german cars you had to switch a fuse around or a wire or something and then it would blink morse codes for the error codes 😂
These old Cadillacs are so cool, Back in the day anyone that drove one was a B.T.O. " Big time operator". You get that old car dialed in, you're going to fall in love with it.
This. I don't really care about a $28,000 engine you got for free in exchange for sponsor plug and build a car none of us can afford. Keep it real is where it's at. Derek is awesome.
As much as I hated wire wheels when I was detailing cars. (Man they're a pain in the downstairs area) And even though they said Oldsmobile. A caddy just doesn't look right without them. Thanks for making me laugh as always, you honestly make a guy feel better 👍🏻
@@402kev4 I think the Cadi covers look good though, especially since they matched the interior color and that's how the car might have looked originally
I perused the comments but didn't see anyone mention it. The bleep bloop box you pulled out had a reman sticker on it already. That means someone had already changed it once. Also I noticed how easily you pulled the one EPROM. It made me wonder if it wasn't loose and that's why it ran earlier and then quit. Just my observations... Nice to see the old girl running even if I'm not a Cadillac guy.
been watching for years. Derek, keep this as original as possible!! its a 2 year option car thats SO close to being 100%! this thing would be rolling working history if you keep it all original working! dont give up. cant wait to see more of this thing on the channel. best car u own!!
I love the fact you switch from a full build of a pick up, to a problem child caddy and still show on your other channel the real life of owning and building your infrastructure. I look forward to every episode.
Hi Derek I'm soon to be a fellowern Tennesseer. Spent 25 years in Olds and Caddy stores shops. That wire to the trans is needed for 4-6-8 opperation. The solenoids that push the rocker arms over failed alot. Most people did disconect the trans. Overheating a problem also fan clutch failure and rad airflow must be clear. Sometimes took a few atemps to burp the system.. As for the wirecaps look for caddy emblems a simple swap or a feller might glue them. Your hardest part is the bumper fillers first to be eatan by the sun . I'll be a watchen.😇
lots of aftermarket bumper fillers available these days, I guess there's a big enough market for vintage Cadis to keep them injection molding new ones in a certain country in Asia
I also do vintage computer repair, and watching you yank those chips then try to cram em back in was terrifying and hilarious. :) I recommend a chip puller, a pin straightener, and some DeOxit D5 if you ever have to do that again.
Hey, those black spider legged things are what the original IC's (integrated circuits) looked like. In my early days (mid to Late 1960's) I worked for Texas Instruments, where we built the huge electronic machines that were designed to Test those EC's. I didn't have the smarts to design them, I was just one of the assembly Techs that assembled those monsters from the frame up, including doing all the soldering work on the circuit and ran all the wiring harnesses throughout the machine. It was the best time of my young college days. I loved it.
I was a tech for an electronic safe company in the 90s and remember having to swap those out to upgrade features on our equipment or to make one CPU board fit another model. We sometimes had to reflash EEPROMS and erase them with the UV light box. Good times!
I realize this vehicle could easily make a fella frustrated to no end, so just watching the never ending clever humor just truly makes my day. Thank you for producing all of the hands down best you tube channel.
I worked as an electronic tech in the 80's and I was cringing when Derek first started to put the PROMs in the reman PCM. He got it done though without bending up the pins. Nice job! As always a very entertaining video.
Former tire guy here. That area on that rear tire is ok. Now, if it was bulged out, then a guy has something to worry about. That means separated steel belt in there.
minus the microcontrollers. The rest of the box is just capacitors, relays, resistors, transformers. without the brain the new ECU circuits are junk. I'm guessing those chips, preprogrammed are impossible to get.
I’m 42 and my first car at 16 was my grandfathers 1970 Cadillac Sedan Deville. My grandparents were poor children of immigrants in the early 1900s in Oklahoma and eventually moved to California when it didn’t suck in the 1930s. Lol! They loved Cadillac and then finally in the 80s when they could finally afford some used ones they got a 68, 69 and a 70 over the years and finally felt like they had made the big time. I remember driving around with them in the 90s as a kid thinking I was the coolest kid going to church or when they would pick me and my cousins up after school to help on the farm. When I was 16 my grandfather sold me his 1970 Sedan Deville for $1000! It was almost mint in 1998. Most kids were driving old 80s imports or 90s if they were lucky. I was rolling in this 1970 pimp ride! I wish I never got rid of it.
Man that's a cool story! Yes, there was once a time when when California didn't suck. LOL It slowly started to happen in 1963 when the state of commiefornia adopted their own emissions standards on passenger cars TEN years before the federally mandated EPA and CAFE standards mandates on passenger cars. Then, that went bad from the automotive aspect into the economic policies side of things slowly but surely and fast forward to their ridiculous property taxes and cost of living as a whole today. 😢
@@trickyricky12147 Yeah California made automakers stop putting road draft crankcase vents in cars, mandating the evil PCV valves which incidentally also help keep the rings in contact with the cylinder walls. Despicable.
Owned the top of the line version of this car at the end of the 90's. Original, low miles, one elderly owner car. Very deluxe, Kelsey Hayes real wire wheels. Put a boatload of work and money into it. Nothing would ever stay fixed. The insulation on the huge bundle of wires in the door hinge reminded me of dried silly putty, fell off in inch long chunks. These cars were still in the wrecker yards then and I had multiple computers, TBIs, etc for "just in case". So, so many problems. It just never ended. I loved it so, I gave it the best I had, and eventually, it just broke my heart. If you don't hate Caddys yet, this car will fix that for you. Run away, save yourself.
Idk...I own an identical car to this one,two 1990 Brougham, and a 1992 Brougham. They have been hands down the most reliable vehicles I have ever owned. They rarely need anything,most of the work I do is cosmetic and routine maintenance. If you get one thats been badly neglected, I suppose it could be a different story.
Really surprised you haven’t installed An exhaust port to your overhead doors so you can get the exhaust outside of your fabulous building. A guy needs to use his lungs a while longer and it also make it safer for your little people. Really enjoy the channel, and how much you care about and work to make your family a part of what you do every day. Keep on keeping on blessings to you and yours
When I was younger, my father used to go to a junkyard where the family worked on cars in a garage with the doors closed. Eventually, they all developed health problems, and then they sold the business.
My Dad had one of these brand new. Drove it two days and brought it back to the dealer and said he never wanted to see it ever again. By the way he had the exact same color like yours. They gave him another one without that crazy engine.
This episode really brought back memories. I was a young Service Director of one of the largest Cadillac stores in the Metro Detroit area in the late 70's to mid 80's. Thanks for your shout out of respect for the techs in that era. That car caused a lot of lost sales to Lincoln. Unfortunately, it was replaced by the HT4100 the following year. Many more years of heartburn for Cadillac. Love your channel and stuff on TV. Wish you and your beautiful family continued success. One last thing, I learned very quickly how to manage and turn around an upset customer or a overworked and upset technician trying to get their 8-6-4 back on the road.
GM should really have stuck with the 425 that this platform was engineered to contain. The 4100 became a good engine ten years later, but had no business being in a C body RWD DeVille. Even the 368 was a better choice, versus losing 100cid and a lot of cam bearings. A 7 liter V8 with multiport fuel injection that could modulate its displacement.. that would be modern today, and is what GM should have built back then. But shareholders like cheap.
@@Bolton115 the refinements and expanded displacement of the 4100 family were great in less time than that IMO. I had the 4.5 and 4.9 in the two Seville STSs that I owned, and they both had decent power to move a nearly two ton car. Reliable, too.
How cool is this Derek took on the challenge to fix one of the most problematic engines and rose to the occasion occasion Hats off to Vise Grip Garage.
The Card Catalog and the Dewey Decimal system! My Mom ignited my love of the library back in the 70s! I totally remember the index card thingamabobber!
The neighbor across the street from my grandmother was the guy who put that Cadillac book together every year, that was his job. Strange living in the Detroit Suburbs how you meet so many people with cool jobs. Love you guys brother! ❤
My husband worked on those at the Cadillac dealership years ago. He said they were a pain in the bottom. 😅 He is explaining everything to me as we watch. He now teaches college in Ontario
Man I loved your tv show. Father and I got sick with COVID a year ago and we binge watched your show. Your channel finally showed up on my fyp, and I started watching! Love your funny humor; keep it up!
Derek, your patience is inspiring. Your bravery too. If I opened the hood and saw the hose factory that exploded under there, I'd a just closed it again and sent it on it's way. I sure appreciate being able to relax, learn a thing or two, and get encouraged by your videos. Thanks to you and your wonderful family for all you do!
Dereck, you are the wizard, the magic man, the grand master! A fellar can certainly learn a thing or two from you. Almost forgot to say, What a brave man you are. Your wife & kids are lucky to have you too.
My uncle bought this exact car. Same year, color, hub caps and engine. I recall it being rather gutless, but the engagement of the 8-6-4 system felt like a trans shift, so not bad at all. They really didn't have much trouble with it at all.
Had a Cadillac 8-6-4 sedan .. white with red leather seats. Was a great ride up and down the east coast. Great at highway speed, but a pain at city driving, shifting back and forth through the active cylinder changes. Six cylinders was terrible. We finally put a toggle switch in to by pass the cylinder changes.
My dad bought one of those it worked great the 1st 4 months and went to the shits!!! They worked on it under warranty until it ran out. They ended up giving him a FULL REFUND An he bought a olds 88 , best car ever...
LMAO, when messing with the gas tank Derek says "how do I..." and for whatever reason here I am thinking 'liiiiive without you' and what do you know our guy follows up saying the same thing. I damn near died laughing
Hey Derek! I live in Burnsville MN... loved watching you back in the day... still love your videos, never miss one. My dad passed last Tuesday... he had no idea what RUclips was let alone who you are... but I enjoyed your videos through a tough time... he didn't give a crap... but I give a crap. Thanks!
DEREK! Hold down OFF, then keep holding it and hold down WARMER!! Same for clearing codes hold down OFF, then hold down HI. This brings back a lot of memories, most of them bad 😀
Codes have to cycle three times then back to start of sequence, then you can clear it. Same as the 4100's and the 4.5's after the 4-6-8. Sadly I was a dealer tech in the early 90's and the "new guy" me, got the 4-6-8's, the 4100's and Allantes, I was like hazing for the new guy. Of course you can rarely get all of the codes cleared for very long. Several eprom revisions did come out that made things better though. That was how you updated the ecu back then, new proms from the parts department and send the old proms back.
I was telling him that the whole time - if you can see the temp changing, then it isn't working. It's the same with a lot of (now) old tech, simultaneously pressing means press one, and keep it pressed then the other. Add to that, that those old buttons usually work badly at best, it's hard to make 3 seconds of connection with them.
@@perfecttommy6952 You and I had the same nightmare career paths. I really do still have bad dreams of the shitty dealers and Cadillacs that I worked on or for.
Oh well, if you wanted to know about one of these, I was the guy. I worked as a tech in a Cadillac dealership at the time those came out. Truth that it didn't work well. You can't dump gas in a cylinder that doesn't fire. I actually have the book you are going through. It was fun working on those things!
I am loving this restoration let’s go and try to get this gal completely running!!! You are the first person on RUclips that’s tried this in depth. I don’t know how you have found all of this information because I have run into a lot of dead ends!!! Love it Derek
My 78 was also known to wake me up in the middle of the night when it was humid, the moisture would somehow set my horn off all by itself, so I would have to disconnect the battery, my neighbors loved me😂
My cousin Jimmy idolizes you! He talks like you, dresses like you, has all your merch, has a mullet....even has pictures of you in his bathroom! So I had to check out your channel. Good stuff, the wife and I watch it together, it's become our thing together. Keep up the great work!
We used to own one of these 4-6-8s. The GM dealer mechanic cut a transmission sensor wire to disable it. He said it was the best way. Our 368 was carboned up, and it shook a bit running on 6, so that's why we cut the wire, but ours actually worked, and saved some gas before that. Ours turned out to be a rare 2 door Fleetwood Brougham. Gold, white and chrome!
Your mechanic didn't do you a favor. Shoulda just run some GM top end cleaner through it, removing the carbon the right way and letting you keep saving the MPGs on the road.
@@Bolton115 it smacks of the same problem that GM's original mechanical fuel injection system had back in the 60s: poorly trained (or just lazy) mechanics taking the easy way out.
That was a one year only disaster for Cadillac! The dealer mechanics just hated to work on them because they never stayed fixed. The “fix” was to clip some wires so they only ran on 8 cylinders. Things got even worse the next year when the POS HT 4100 engines came out. These were followed up by the troublesome Northstar engines. These were dark days for the mighty Cadillac when they lost most of their long time loyal customers.
Dad was a GM mechanic back then, best in the shop so he got saddled with all these junk heaps. He didn't last too much longer, retired and took a job at an elementary school. Cleaning up puke and listening to screaming brats was easy after having to deal with the GM courses every 6 months.
My Dad had a Sedan DeVille this year with the V8-6-4. He hated it so bad, he took it back to the dealership and made them take it back when it had 5 or 6000 miles on it. And replaced it with the HT4100!!!! He bought a Lexus after that and would never consider a Cadillac again.
@@RedRuffinsore almost everyone of those heaps sold came back and got scrapped. The small block diesel conversions were also a great sales move (for every other company)
Glad you finally got it going, enjoyed the video. Brought back memories of my dad's 4/6/8, 4 door gray Fleetwood , many road trips, he put 250k miles on it.
Clearing Trouble Codes - During trouble code display: Simultaneously press and hold ‘OFF’ and ‘LO’ buttons When ’00’ is displayed: Release the ‘OFF’ and ‘LO’ buttons To end diagnosis: Press the ‘AUTO’ button, or switch ignition OFF for 10 seconds
A sex bot copied your comment and got lots of praise from people for the advice! Even Derek thanked them for your advice! Thought I would give credit where it is due for this good advice!
I did my first headliner 2 years ago and it was so much easier than I thought it would be. I kicked myself for all those years of having crappy headliners. You should include that in an episode. I got the material from Hobby Lobby. They've got the foam backed material just like the original headliners. All you need is a can of 3M headliner adhesive and the material. I took a drill and a wire wheel to get the old glue off the headliner board then I just sprayed it down and laid the new headliner on. It's not really that hard to take out the old headliner board so you can work on it.
Don’t use the aerosol glue, it will fail. Use Formica adhesive in a spray gun, available at big box stores. It is water resistant and will last way longer than the spray can glue.
I'm glad you kept the EFI even though it's a PITA. Most of the ones I saw and have seen had 4 barrel conversions or permanent 8-6-4 deletes. Chrysler had the exact same issues with their early Bendix EFI in the 1981-1983 Imperial, and most of those got scrapped for a good Holley as well. Dealers even offered factory conversion kits. Replace the fiberglass extensions and it would be a good Sunday driver for lunches or going to church. FYI -- retrofit kits for the AC to R134 are available, if you want to keep it, but many of the interior AC parts such as the evaporator are no longer available anywhere. I had an '87 Fleetwood in the shop years ago that was owned by a nice older gentleman, we had done the 134a conversion and it needed a condenser, looked for 6 months and had to resort to pick-n-pull.
Derek has a carb swapped Imperial too, I think he intentionally seeks out these kinds of challenges to punk the dealer mechanics who cried about them back in the day. It's a great flex IMO.
Even back then, liberal loons convinced much of the population that the world was going to end in 5 years if we didn't change our entire ways of lives and give those at the top more control over everything and make it infinity worse.
Minimum wage varies from state to state. It was $3.25 in 1991 when I started my first job. I made $ .10 over & thought I was making decent money. Gas though was only $ .90 a gallon then too. I worked in the next state over from where I lived. In the state I lived in it was something like $2.65 if I recall.
@@stevemccauley5734back in the early 80s, I was an agricultural mechanic. My boss offered me a $.05 an hour raise. That raise would buy me a can of Pepsi a day.
@@stevemccauley5734 Just a quick clarification Minimum wage is Federal. While states can implement their minimum, if Federal is higher, employers must pay it. So yes states can state a higher minimum than federal, but not lower.
There's something relaxing about watching one full hour of Derek doing the all work and getting dirty, so we don't have to. And we learn a few things along the way. Good deal!
My respect level for you just went up even more ! I'm glad you went back after it. Most people would run away from that car due to all the problems they had.
Yes, Mr. Derrick, sir. I remember the index cards. I remember going to the local library walking up to the card catalog and following the dewey decimal system in order to find the book I wanted.
Derek I have to say that I have never seen a brake drum take off like that in all my years as a mechanic I’ve seen oxygen tanks blow through the wall, but never a drum rolling on the ground like that 🤣🤣🤣🤣🤣🤣🤣
On my 81 Coupe DeVille, the mechanic disconnected a wire that went to the transmission, then it ran perfectly on 8 cylinders all of the time. I never had a problem with that engine.
Gotta say, sittin here on an aussie Saturday afternoon enjoying a beer, and watching Derek work his magic, is a darn good day ! Ohh, and a fella did a pretty darn good job on the exhaust fitment there too !
Do you guys in Aus still have any old iron and v8 engines lying in junkyards? Here in my country malta have we absolutley nothing..if it wasn't for the British building an airstrip here during the war we wouldn't even have a drag strip.
@davidgalea6113 they're still lying around, although nowhere near as common these days, and in my experience, people tend to hang onto old stuff more now too
Many years ago I wad diagnosing a early 1990s GMC van with the 4.3L V6. It was a crank/no start condition. I went thru all of the basics, ignition, fuel, spark and air, everything checked out fine. Engine wound up flooding thru the diag. process, so I replaced the spark plugs, and changed the oil. Anywho, this vehicle wasn't O.B.D.II, I went home and thought about it, went back to work, dusted off the OBDI, pulled up live stream data and saw the coolant temp was stuck at -40. Well, I replaced the coolant temp sensor, and guess what, the van fired right up. Long story short, the van wad dumping too much fuel because the computer thought it was -40 out(it wasn't, it was summer at the time). So, yes, coolant temp sensor fault can cause a crank/no start
Had the same thing happen with a 89 celebrity, it was my grandma's car and she had trouble for 10 years or more with it stalling then wouldn't start, wait a while and it was fine. She took it to dealers and independent shops and nobody could figure out why. I had it at my house working on brakes and it decided not to start, I looked at live data and sure enough, -40. I changed the sensor and it was fine after that 😂
@@kellismith4329microfiche! Haven't heard that in a few. I had to learn how to use that system when the Army started putting their supply system on that.
Derek I hope you see this, I greatly appreciate all the hard work on your videos lately, but please next week take a breather and spend some quality time with your family.
Well it's time to pull that old caddy out. And put a coyote under the hood be different put something under the hood other than an LS. Guys on half joking but. Just do something different. And then drive the wheels off that thing
This might be one of my favourite revivals its unique and really out of the box for a carburettor guy hope we see more stuff like this even though my heart is full of carburettors or i should say fuel make it hapeners keep it going big fella!
Ihave a 87 Monte Carlo SS 305 HO. Shes all original electrodigicals under the hood and runs like a top. I was one of those 80's Techs that had to repair all this madness, but once you got the hang of it there was no issue with what was going on. I'd be glad to help you out there Derek! I'll bring the cold snacks!👍
Gee, it's funny how nowadays, that computer processing has caught up with the ideas from back then, that several makes now have modulated displacement engines that turn off some of the cylinders at various times to save gas. Also, if you have one of these cars now, GM stuck with them til into the '90s-meaning the later PROMs give 30 percent more power than the car had when it was new. What other '80s car could get a factory provided chip that gave it 30 percent more ponies in its power barn?
This has by far been the best video VGG has done… had me rolling and knee slapping laughter! I watch this channel all the time and always learning from it! Thanks Derek!
Derek, my dad and I have been fans for many years. Thank you for all your family friendly content you produce, it is refreshing to watch when it seems like there is just so much filthy content now-a-days on youtube. Also, my dad and I are big jeep enthusiasts (like the older pre-2000s era). Any chance you may scoop up a an old cherokee, wagon, or wrangler? I think many on this channel would love to see a jeep of some sort. Thanks!
Derek. Thank you for what you do. I can't thank you enough. Words really don't convey. To start off, I'm not a car person by any stretch. Maybe I'm a little sentimental. I have an 81 EFI Sedan DeVille sitting in the shed at the farm that was left to me by my Granfather. He also left me an 80 f100 with a currently very tired 302 that I'm still driving today. As a child one of the things that I remember most was how upset he was when my Dad told him he was going to give it a carb if he ever owned it. My Grandpa's response was "Then you never will, this is a part of history." He kept claiming how he would take it to a shop and get them to work on it. But it was always too expensive. I never knew this was a part of true automotive history that we'd never get back. I never paid attention. He passed away in 2020 and I was left with the car. I have very little money and automotive knowledge, but a coworker of mine recommended your channel today at work. She said she and her husband started working on her Dad's old Dodge pickup and was telling me just how entertaining you were. Her exact words were 'He's that guy who is a teacher without knowing he's a teacher'. It's something the two of them have truly bonded on. Anyway - her telling me about your channel, well, that got me into a discussion about this car. I had no idea it was this rare. Like I said, I'm not a car person. But I happened to bring up this car. I couldn't remember what kind of Cadillac it was until she showed me both of these videos later that evening. And now here I am at 11 pm packing to take a trip up there to get my ol' paws under the hood and in the mitten box and see what trouble I can get into. Who else calls this a mitten box? You are truly one of a kind. My coworker couldn't have been more right. You are the motivational speaker and teacher some of us didn't know we needed. The three of us are going to try and get my Sedan DeVille running this weekend. It's a car, most of the world would say. But it's a part of history that needs to be kept alive. I hope you find a tired early 80s 302 in an f100 to rebuild and made as strong as it can be. You truly are an inspiration.
Derek my father passed away a couple of days ago from cancer he was a big fan of yours and also love watching vise grip garage he always say you catch phrases and stuff that you always say on your videos So thank you for entertaining my father over the years when he was a subscriber/watcher
Sorry for your loss . It's been a few months since I lost my dad to cancer. Starting to come to grips with it. Hang in there, friend.
@@tonyriehle6657 I don't know if I would ever come to grips but I have to be there for my mom and also keep my promise by fixing his late '90s Chevy suburban and his 82 Chevy pickup truck
Sorry for your loss
Sorry for the loss of your dad and a fellow vice gripper 😔
Lots of love to you and the family
I was a Cadillac tech during the '80s. I don't miss working on those rolling nightmares. To clear codes, pull the ECM BATT fuse for 15 seconds. Don't worry about those dents in the tire sidewalls, it's just where the cord plys are joined.
rolling nightmares 🤣🤣🤣
I was 14 when a good friend’s mom got one in 1980 around thanksgiving. The family owned a Buick franchise by Christmas it had been towed back to Cadillac a couple of times. By new years she had a 1981 Buick park avenue.
@steventerlinden7374 Will pops 🎉 🎊 😂😂😂😂😂
My neighbor had one of those and didn't seem to have too many problems with it, but she inherited it from her Father when he passed, so maybe it had all of the fixes by then. I drove it a few times and have to say it rode like a, well, Cadillac. Nothing like it. If they made a new one just like it today with a reliable drivetrain I'd be in on one for sure. If I ever find one of these old ones in decent shape I'd grab it and see about updating the power plant. I'm getting old and while I like my noisy supercharged F150 Harley Edition, I could go for a silent ride on the clouds from time to time.
Have an in-law who repairs old ECMs. Bottom line, the capacitors leak and dissolve traces on the circuit board. They just recap these things, neutralize any capacitor acid with baking soda, and call them remanufactured. 😂 Anything with EFI which was made in the 1990s or earlier is on borrowed time. Early 2000s ECMs are apparently seeing more failures too. Niche business I guess?
I just loved my GM headliner. On a cold day, it would drop down on my head and keep it warm. What an innovation.😂
LOL Yes it was the winter hat delete option (think it was option code GMSFU) or you could make fun decorative patterns on the ceiling with thumbtacks in order to keep it up like I did on my 79 Cutlass.
My 85 Cutlass looked like Hellraiser... IYKYK
I had an 81 DeVille with the same problem. That didn't make any sense !@@d.g.566
The standard of the world. GM slogan for Cadillac Fleetwood and DeVille. Headliners on both cars were crap and they were not easy to repair or replace.
You must be bald??🎱
Your reaction when it fired was pure and real! We can tell that you had absolutely zero expectations that this turd was ever going to fire or run! Excellent.
YAAHOOOO GOT IT 😮😂
That’s what I thought, the unmitigated glee that it worked is one reason this channel is so …real for lack of a better term
And it puts a smile on a fellas face every time
Great reaction, but I still think he was more surprised by liberty chevelles first fire
Need to find some covers around the tail lights
A few of his videos have these moments, and its still a surprise to me as well each time!
My grandfather was a Cadillac master and worked for Sewell Village for 27 years. He retired in '89 and unfortunately, we lost him in 2001. He'd love this series and would probably be cussing that design. :D
Late 80's I was a GM technician. Roger Garner Chevy. Cadillac wiring specialist. Drivability and engine rebuild. Those were Good challenges!!! Thank you for sharing this beast of a car. I owned an 8,6,4. Loved it !!!
Best line in the WHOLE video at 17:53...."If I remover this again its gona be with an axe and a fire exstingguisher".......I was ROLLN !!!
Not bad lol I got a pretty good chuckle out of this is the title ! After seeing he wrote all over it !
Had me laughing pretty good 😂😂
Had me in shits and giggles too
Me too!
Exactly what I was thinking.
From 1990 to 2000, I was the Union Representative at Don Rosen Cadillac, just outside of Philly. In 2000 they sold the Franchise back to GM, as part of GM Project 2000. They had 4 Cadillac Master Craftsman who worked there and they were the Best Cadillac Flat Rate Technicians, I ever saw during my 47 years in the Automotive Mechanic Profession. Love the channel, it warms my old retired Mechanic heart.
Absolute respect for keeping the original solution and trying to get all the features of it working!
Died when you slapped that electrical tape over that check engine light after all that 🤣
That's what my dad did too with his Bronco back in early 80's.
***SPOILER ALERT***
I worked as a driveability technician at a gm dealership back in the late 80s until mid 2000s. Cadillac was the worst to work on. Gm had software updates for every car to address multiple running issues, so you had to order a new prom, then install it when it came in. Once gm switched to EEPROM systems, it was way easier. We simply downloaded new updates thru the tech1 terminal and uodate using the OBD1 port. Also, code 12 is used as a self check for the ecm, it always states no tach signal as the engine is off during code check. Codes can be erased by simply disconnecting the battery for at least one minute. Also, after it cycles thru 3 read cycles, you you can erase the codes by pressing off and hi. Once it reads 00, codes are cleared
In 1993 I had a 84 Cutlass Ciera Brougham. Tech at dealership in Quaker-town PA was mad I wanted to replace OBDI PROM that was causing Check Engine light to come on. I was stubborn young punk who wouldn't listen to him and wanted to keep the car in original condition. I was a purist who didn't want to drive Cutlass with Check Engine light on. I was an old school car ethusiast whose motto was "if you can't do it right , don't do it all." All I care about is winning. If it costs $5000 or more to fix a problem I don't care. If the car can't run without the Check Engine light I'll junk the f**king thing. Even if I lose thousands of dollars. It's like getting rid of a whore who's outlived her usefulness. Snowflakes. Cry me a f** king river. Man up or junk it the ho or the car.
"Cadillacs are the worst to work on" then you go on to describe the built in diagnostics from 1981 that other kinds of cars still don't have today, over 40 years later. Diagnostics that involve pushing a couple buttons on the dash to get codes and even cycle the 8/6/4.. ahead of its time. Why don't you try to diagnose those '80s L Jetronic systems on German cars.. 😀 I was also a mechanic back then, and I'll take pushing OFF and WARMER any day over counting VOM needle swings on a Ford. Chrysler was also notably easy for back then, IIRC starting in '83 you could just cycle the key three times in five seconds to get codes out of the Check Engine light.
I'm glad the '80s are over in terms of how they made cars. Yes, all of them.
@@Bolton115 yes, I worked on Ford's and imports too, still have my breakout box somewhere for the ford eec-4 system, and yeah, did several k-jetronic fuel systems, and I agree, modern computer systems are easier to diagnose the problem. My comment was on the Cadillacs they wanted you to use the onboard diagnostics, where the tech1 scanner was much faster to use, instead of all the sub menus you had to go thru on the Cadillac.
Cadillac provided on board diagnostics because no one had a Tech One, Snap-On 3000 (IIRC) or other cartridge based scan tools yet. The ALDL reader in 1983 was a Sun Interrogator that was the size of a console television and had a box of floppy disks and adapters for various '80s cars. In 1987, my high school auto mechanics class went on a field trip to the VoTech college and they had one. It was pretty impressive for its time.
I still maintain that Cadillac were pioneers in this area. No other cars had the computer control and self diagnostics for several years yet -even other GM models-and being able to troubleshoot it with its own dashboard display and a manual is something I still can't do with most 20 years later models.
Ok, well now that they all have great big screens and you're more IT guy than auto mechanic.. now you can.
@@Bolton115 I remember that on some german cars you had to switch a fuse around or a wire or something and then it would blink morse codes for the error codes 😂
These old Cadillacs are so cool, Back in the day anyone that drove one was a B.T.O. " Big time operator". You get that old car dialed in, you're going to fall in love with it.
I still like the fact you’re keeping it simple no over budget builds like the other channels, thanks for keeping it real.
This. I don't really care about a $28,000 engine you got for free in exchange for sponsor plug and build a car none of us can afford. Keep it real is where it's at. Derek is awesome.
Always!
As much as I hated wire wheels when I was detailing cars. (Man they're a pain in the downstairs area) And even though they said Oldsmobile. A caddy just doesn't look right without them. Thanks for making me laugh as always, you honestly make a guy feel better 👍🏻
@@402kev4 I think the Cadi covers look good though, especially since they matched the interior color and that's how the car might have looked originally
I perused the comments but didn't see anyone mention it. The bleep bloop box you pulled out had a reman sticker on it already. That means someone had already changed it once. Also I noticed how easily you pulled the one EPROM. It made me wonder if it wasn't loose and that's why it ran earlier and then quit. Just my observations...
Nice to see the old girl running even if I'm not a Cadillac guy.
yeah that bliip bloop potato chip was definitely loose. It probably would've worked right away... no, probably not.
also, on that note, it's more than likely that the hatch thingy was from the original box.. would explain why it was so extra crunchy
been watching for years. Derek, keep this as original as possible!! its a 2 year option car thats SO close to being 100%! this thing would be rolling working history if you keep it all original working! dont give up. cant wait to see more of this thing on the channel. best car u own!!
Electronics nerd here... Derek working the DIP28 sockets - that's pure gold! 😀
Leaving the incandescent footwell bulb running right over them with no shielding was less pure gold
I love the fact you switch from a full build of a pick up, to a problem child caddy and still show on your other channel the real life of owning and building your infrastructure. I look forward to every episode.
Hi Derek I'm soon to be a fellowern Tennesseer. Spent 25 years in Olds and Caddy stores shops. That wire to the trans is needed for 4-6-8 opperation. The solenoids that push the rocker arms over failed alot. Most people did disconect the trans. Overheating a problem also fan clutch failure and rad airflow must be clear. Sometimes took a few atemps to burp the system.. As for the wirecaps look for caddy emblems a simple swap or a feller might glue them. Your hardest part is the bumper fillers first to be eatan by the sun . I'll be a watchen.😇
lots of aftermarket bumper fillers available these days, I guess there's a big enough market for vintage Cadis to keep them injection molding new ones in a certain country in Asia
I also do vintage computer repair, and watching you yank those chips then try to cram em back in was terrifying and hilarious. :) I recommend a chip puller, a pin straightener, and some DeOxit D5 if you ever have to do that again.
I do too. I also cringed when he did that - but I love the guy, and well it worked ok !.
I was screaming NOOOOOOOOOOO at the screen 😂
Ha ya I think he got too big for comment section also..making $$$
I guess he wasn't concerned about the static electricity or bending the pins.
No antistatic wrist strap for Derek.
This man is a hero. He suffers on these horrid repairs for our entertainment and knowlege. Salute*
Hey, those black spider legged things are what the original IC's (integrated circuits) looked like. In my early days (mid to Late 1960's) I worked for Texas Instruments, where we built the huge electronic machines that were designed to Test those EC's. I didn't have the smarts to design them, I was just one of the assembly Techs that assembled those monsters from the frame up, including doing all the soldering work on the circuit and ran all the wiring harnesses throughout the machine. It was the best time of my young college days. I loved it.
I was a tech for an electronic safe company in the 90s and remember having to swap those out to upgrade features on our equipment or to make one CPU board fit another model. We sometimes had to reflash EEPROMS and erase them with the UV light box. Good times!
I realize this vehicle could easily make a fella frustrated to no end, so just watching the never ending clever humor just truly makes my day. Thank you for producing all of the hands down best you tube channel.
Thank you so much.
You noticed too Derek is very cool headed. Big problems are a minor frustration to him a real professional automotive technician.
@@enzoonymus3084 one other mech in this comment section called them "challenges," I think they're on the same page
I worked as an electronic tech in the 80's and I was cringing when Derek first started to put the PROMs in the reman PCM. He got it done though without bending up the pins. Nice job! As always a very entertaining video.
I was basically holding my breath at that point and wondering how he was ever going to find replacement PROMs.
Pretty sure my heart stopped beating until I saw those PROMs in.. 😂
Former tire guy here. That area on that rear tire is ok. Now, if it was bulged out, then a guy has something to worry about. That means separated steel belt in there.
You might be the first person in the history of the planet that bought a reman ECM that actually worked out of the box.
minus the microcontrollers. The rest of the box is just capacitors, relays, resistors, transformers. without the brain the new ECU circuits are junk. I'm guessing those chips, preprogrammed are impossible to get.
from Mexico no less 🤔
I got one for my car that fixed all my issues was very happy
Somebody call guinness book of world records!
Me to.@@Lazerchicken69
I’m 42 and my first car at 16 was my grandfathers 1970 Cadillac Sedan Deville. My grandparents were poor children of immigrants in the early 1900s in Oklahoma and eventually moved to California when it didn’t suck in the 1930s. Lol! They loved Cadillac and then finally in the 80s when they could finally afford some used ones they got a 68, 69 and a 70 over the years and finally felt like they had made the big time. I remember driving around with them in the 90s as a kid thinking I was the coolest kid going to church or when they would pick me and my cousins up after school to help on the farm. When I was 16 my grandfather sold me his 1970 Sedan Deville for $1000! It was almost mint in 1998. Most kids were driving old 80s imports or 90s if they were lucky. I was rolling in this 1970 pimp ride! I wish I never got rid of it.
Man that's a cool story! Yes, there was once a time when when California didn't suck. LOL It slowly started to happen in 1963 when the state of commiefornia adopted their own emissions standards on passenger cars TEN years before the federally mandated EPA and CAFE standards mandates on passenger cars. Then, that went bad from the automotive aspect into the economic policies side of things slowly but surely and fast forward to their ridiculous property taxes and cost of living as a whole today. 😢
@@trickyricky12147 Yeah California made automakers stop putting road draft crankcase vents in cars, mandating the evil PCV valves which incidentally also help keep the rings in contact with the cylinder walls. Despicable.
as a guy who rebuilds pinball machines and arcade games..and struggles with auto repair...watching you struggle with the PROMS was pure joy
Owned the top of the line version of this car at the end of the 90's. Original, low miles, one elderly owner car. Very deluxe, Kelsey Hayes real wire wheels. Put a boatload of work and money into it. Nothing would ever stay fixed. The insulation on the huge bundle of wires in the door hinge reminded me of dried silly putty, fell off in inch long chunks. These cars were still in the wrecker yards then and I had multiple computers, TBIs, etc for "just in case". So, so many problems. It just never ended. I loved it so, I gave it the best I had, and eventually, it just broke my heart. If you don't hate Caddys yet, this car will fix that for you. Run away, save yourself.
Agree, I figured Derek gave up on it after it first beat him. Hope it ultimately works out for him!
Idk...I own an identical car to this one,two 1990 Brougham, and a 1992 Brougham. They have been hands down the most reliable vehicles I have ever owned. They rarely need anything,most of the work I do is cosmetic and routine maintenance. If you get one thats been badly neglected, I suppose it could be a different story.
@@wessteenrod used cars can be a good economic option once you get past the "deferred maintenance" of previous owners.
Really surprised you haven’t installed An exhaust port to your overhead doors so you can get the exhaust outside of your fabulous building. A guy needs to use his lungs a while longer and it also make it safer for your little people. Really enjoy the channel, and how much you care about and work to make your family a part of what you do every day. Keep on keeping on blessings to you and yours
Ive always thought the same thing. I wouldnt be able to stand those old vehicles running inside like that.
Have you seen how enormous that building is inside? It's gonna take a lot of exhaust to even make a dent
When I was younger, my father used to go to a junkyard where the family worked on cars in a garage with the doors closed. Eventually, they all developed health problems, and then they sold the business.
@@Demoralized88 yeah but it stays near ground level, so you don't get the whole volume of the building to disperse it, only the square footage
@@williamalexander1743 they were probably smokers too
Please. This is 1 of those cars that has to live and be restored. Go on VGG, give us a full resto❤
I'd love to see that
My Dad had one of these brand new. Drove it two days and brought it back to the dealer and said he never wanted to see it ever again. By the way he had the exact same color like yours. They gave him another one without that crazy engine.
The best VGG are when derek is struggling and confused. Need more like this 👍👍👍
This episode really brought back memories. I was a young Service Director of one of the largest Cadillac stores in the Metro Detroit area in the late 70's to mid 80's. Thanks for your shout out of respect for the techs in that era. That car caused a lot of lost sales to Lincoln. Unfortunately, it was replaced by the HT4100 the following year. Many more years of heartburn for Cadillac. Love your channel and stuff on TV. Wish you and your beautiful family continued success. One last thing, I learned very quickly how to manage and turn around an upset customer or a overworked and upset technician trying to get their 8-6-4 back on the road.
GM should really have stuck with the 425 that this platform was engineered to contain. The 4100 became a good engine ten years later, but had no business being in a C body RWD DeVille. Even the 368 was a better choice, versus losing 100cid and a lot of cam bearings. A 7 liter V8 with multiport fuel injection that could modulate its displacement.. that would be modern today, and is what GM should have built back then. But shareholders like cheap.
@@Bolton115 the refinements and expanded displacement of the 4100 family were great in less time than that IMO. I had the 4.5 and 4.9 in the two Seville STSs that I owned, and they both had decent power to move a nearly two ton car. Reliable, too.
Dad was a Cadillac mechanic from 1955 to 1989. It's something to see all these details again.
How cool is this Derek took on the challenge to fix one of the most problematic engines and rose to the occasion occasion Hats off to Vise Grip Garage.
The Card Catalog and the Dewey Decimal system! My Mom ignited my love of the library back in the 70s! I totally remember the index card thingamabobber!
The neighbor across the street from my grandmother was the guy who put that Cadillac book together every year, that was his job. Strange living in the Detroit Suburbs how you meet so many people with cool jobs. Love you guys brother! ❤
All the old school Cadillac guys were cheering when you finally said "off and warmer". 😊
I had a factory limo 1981 10 passengers when we retired it car had 360k on the clock the 4V6/8 worked perfectly.
My husband worked on those at the Cadillac dealership years ago. He said they were a pain in the bottom.
😅
He is explaining everything to me as we watch.
He now teaches college in Ontario
Cool.
Derek you went toe to toe with this caddy and you win by TKO outstanding Job and work and diagnostic!!!!!!!!! You Rock!!!!!!!!!!!!
Thanks, buddy.
Man I loved your tv show. Father and I got sick with COVID a year ago and we binge watched your show. Your channel finally showed up on my fyp, and I started watching! Love your funny humor; keep it up!
Derek, your patience is inspiring. Your bravery too. If I opened the hood and saw the hose factory that exploded under there, I'd a just closed it again and sent it on it's way. I sure appreciate being able to relax, learn a thing or two, and get encouraged by your videos. Thanks to you and your wonderful family for all you do!
Dereck, you are the wizard, the magic man, the grand master! A fellar can certainly learn a thing or two from you. Almost forgot to say, What a brave man you are. Your wife & kids are lucky to have you too.
My uncle bought this exact car. Same year, color, hub caps and engine. I recall it being rather gutless, but the engagement of the 8-6-4 system felt like a trans shift, so not bad at all. They really didn't have much trouble with it at all.
So happy a guy's working on this unique rigg... The 4-6-8 are just so cool despite everything!
A guy looks at what's going on, and well, been there, done that. You're awesome. Hats off. Had a few wobble pops. I'm old. 70. Thanks.
Had a Cadillac 8-6-4 sedan .. white with red leather seats. Was a great ride up and down the east coast. Great at highway speed, but a pain at city driving, shifting back and forth through the active cylinder changes. Six cylinders was terrible. We finally put a toggle switch in to by pass the cylinder changes.
This car was by far my favorite build video😂😂😂😂😂hilarious!!!
The brake drum rolling out the shop door was an all time classic!
@@oldblueaccord2629Loved how it went between the legs on his tripod without even coming close to hitting it.
The flashback edit on the exhaust was really, just, perfect
My dad bought one of those it worked great the 1st 4 months and went to the shits!!! They worked on it under warranty until it ran out. They ended up giving him a FULL REFUND An he bought a olds 88 , best car ever...
LMAO, when messing with the gas tank Derek says "how do I..." and for whatever reason here I am thinking 'liiiiive without you' and what do you know our guy follows up saying the same thing. I damn near died laughing
Gotta say, fella was watching Cletus on his helicopter and got the notification that VG video was up. Had to say good bye to Cletus.
lol dude same here! Instant change over
Me, too! Im sure Cleeter will put a guy in it at some point
Lmao same
Me three
Haha same
Hey Derek! I live in Burnsville MN... loved watching you back in the day... still love your videos, never miss one. My dad passed last Tuesday... he had no idea what RUclips was let alone who you are... but I enjoyed your videos through a tough time... he didn't give a crap... but I give a crap. Thanks!
Sorry for your loss.
DEREK! Hold down OFF, then keep holding it and hold down WARMER!! Same for clearing codes hold down OFF, then hold down HI. This brings back a lot of memories, most of them bad 😀
Codes have to cycle three times then back to start of sequence, then you can clear it. Same as the 4100's and the 4.5's after the 4-6-8. Sadly I was a dealer tech in the early 90's and the "new guy" me, got the 4-6-8's, the 4100's and Allantes, I was like hazing for the new guy. Of course you can rarely get all of the codes cleared for very long. Several eprom revisions did come out that made things better though. That was how you updated the ecu back then, new proms from the parts department and send the old proms back.
@@perfecttommy6952 I had a 4100, dearlawd. That thing drove me nuts.
I was telling him that the whole time - if you can see the temp changing, then it isn't working. It's the same with a lot of (now) old tech, simultaneously pressing means press one, and keep it pressed then the other. Add to that, that those old buttons usually work badly at best, it's hard to make 3 seconds of connection with them.
@@perfecttommy6952 You and I had the same nightmare career paths. I really do still have bad dreams of the shitty dealers and Cadillacs that I worked on or for.
@@kworld429 The best part is we can watch Derek do this and remember how fortunate we are today.
Oh well, if you wanted to know about one of these, I was the guy. I worked as a tech in a Cadillac dealership at the time those came out. Truth that it didn't work well. You can't dump gas in a cylinder that doesn't fire. I actually have the book you are going through. It was fun working on those things!
U can.... it just still wont run
I thought those solenoids disabled the intake valves so no gas got in?
@@Bolton115 It did but when the vale did open there was a puddle of fuel sitting over the valve that got dumped into the combustion chamber.
@@oneoldmansgarage7880 so when activated it did not clear the fuel that was already there?
I am loving this restoration let’s go and try to get this gal completely running!!! You are the first person on RUclips that’s tried this in depth. I don’t know how you have found all of this information because I have run into a lot of dead ends!!! Love it Derek
My 78 was also known to wake me up in the middle of the night when it was humid, the moisture would somehow set my horn off all by itself, so I would have to disconnect the battery, my neighbors loved me😂
My cousin Jimmy idolizes you! He talks like you, dresses like you, has all your merch, has a mullet....even has pictures of you in his bathroom! So I had to check out your channel. Good stuff, the wife and I watch it together, it's become our thing together. Keep up the great work!
Is your cousin a secret intelligent guy masquerading as a dimwitted farm boy?
Looks WAY better with the wire wheel covers! 🚘
We used to own one of these 4-6-8s. The GM dealer mechanic cut a transmission sensor wire to disable it. He said it was the best way. Our 368 was carboned up, and it shook a bit running on 6, so that's why we cut the wire, but ours actually worked, and saved some gas before that. Ours turned out to be a rare 2 door Fleetwood Brougham. Gold, white and chrome!
Wish it were that easy on my 2017 GMC 5.3 with AFM..
Was probably the High Gear wire that tells it it's in top gear and shit cylinders down. If it doesn't get that signal, it won't do it
Your mechanic didn't do you a favor. Shoulda just run some GM top end cleaner through it, removing the carbon the right way and letting you keep saving the MPGs on the road.
@@Bolton115 it smacks of the same problem that GM's original mechanical fuel injection system had back in the 60s: poorly trained (or just lazy) mechanics taking the easy way out.
That was a one year only disaster for Cadillac! The dealer mechanics just hated to work on them because they never stayed fixed. The “fix” was to clip some wires so they only ran on 8 cylinders. Things got even worse the next year when the POS HT 4100 engines came out. These were followed up by the troublesome Northstar engines. These were dark days for the mighty Cadillac when they lost most of their long time loyal customers.
Dad was a GM mechanic back then, best in the shop so he got saddled with all these junk heaps. He didn't last too much longer, retired and took a job at an elementary school. Cleaning up puke and listening to screaming brats was easy after having to deal with the GM courses every 6 months.
Yup, precisely correct. That's how my parents' was fixed. Just ran on 8.
My Dad had a Sedan DeVille this year with the V8-6-4. He hated it so bad, he took it back to the dealership and made them take it back when it had 5 or 6000 miles on it. And replaced it with the HT4100!!!! He bought a Lexus after that and would never consider a Cadillac again.
@@RedRuffinsore almost everyone of those heaps sold came back and got scrapped. The small block diesel conversions were also a great sales move (for every other company)
I had a Northstar years ago. Sad the engines are junk cuz the car was beautiful
Glad you finally got it going, enjoyed the video. Brought back memories of my dad's 4/6/8, 4 door gray Fleetwood , many road trips, he put 250k miles on it.
Clearing Trouble Codes -
During trouble code display: Simultaneously press and hold ‘OFF’ and ‘LO’ buttons
When ’00’ is displayed: Release the ‘OFF’ and ‘LO’ buttons
To end diagnosis:
Press the ‘AUTO’ button, or switch ignition OFF for 10 seconds
A sex bot copied your comment and got lots of praise from people for the advice! Even Derek thanked them for your advice! Thought I would give credit where it is due for this good advice!
I did my first headliner 2 years ago and it was so much easier than I thought it would be. I kicked myself for all those years of having crappy headliners. You should include that in an episode. I got the material from Hobby Lobby. They've got the foam backed material just like the original headliners. All you need is a can of 3M headliner adhesive and the material. I took a drill and a wire wheel to get the old glue off the headliner board then I just sprayed it down and laid the new headliner on. It's not really that hard to take out the old headliner board so you can work on it.
YES!
Don’t use the aerosol glue, it will fail. Use Formica adhesive in a spray gun, available at big box stores. It is water resistant and will last way longer than the spray can glue.
@@PatDemitras you mean the pink stuff?
I'm glad you kept the EFI even though it's a PITA. Most of the ones I saw and have seen had 4 barrel conversions or permanent 8-6-4 deletes. Chrysler had the exact same issues with their early Bendix EFI in the 1981-1983 Imperial, and most of those got scrapped for a good Holley as well. Dealers even offered factory conversion kits. Replace the fiberglass extensions and it would be a good Sunday driver for lunches or going to church. FYI -- retrofit kits for the AC to R134 are available, if you want to keep it, but many of the interior AC parts such as the evaporator are no longer available anywhere. I had an '87 Fleetwood in the shop years ago that was owned by a nice older gentleman, we had done the 134a conversion and it needed a condenser, looked for 6 months and had to resort to pick-n-pull.
Derek has a carb swapped Imperial too, I think he intentionally seeks out these kinds of challenges to punk the dealer mechanics who cried about them back in the day. It's a great flex IMO.
I graduate from H.S. in 1981. The Gas Saving 864 Caddy was designed. When gas was $1 a gallon and minimum wage was $3.35.
In 1969 minimum wage was $1.60.
Even back then, liberal loons convinced much of the population that the world was going to end in 5 years if we didn't change our entire ways of lives and give those at the top more control over everything and make it infinity worse.
Minimum wage varies from state to state. It was $3.25 in 1991 when I started my first job. I made $ .10 over & thought I was making decent money. Gas though was only $ .90 a gallon then too. I worked in the next state over from where I lived. In the state I lived in it was something like $2.65 if I recall.
@@stevemccauley5734back in the early 80s, I was an agricultural mechanic. My boss offered me a $.05 an hour raise. That raise would buy me a can of Pepsi a day.
@@stevemccauley5734 Just a quick clarification Minimum wage is Federal. While states can implement their minimum, if Federal is higher, employers must pay it. So yes states can state a higher minimum than federal, but not lower.
55:54 Those caps look good, but I like the spokes, good video thanks for showing sharp looking Cad.
There's something relaxing about watching one full hour of Derek doing the all work and getting dirty, so we don't have to. And we learn a few things along the way. Good deal!
VGG showed up today in an MSN article on the 10 Best Car Restoration Shows on TV. They had GREAT things to say about you.
The relay convenience center 😂🤣 The technology a guy has to deal with in this rig is simply breath-taking.
My respect level for you just went up even more ! I'm glad you went back after it. Most people would run away from that car due to all the problems they had.
Yes, Mr. Derrick, sir. I remember the index cards. I remember going to the local library walking up to the card catalog and following the dewey decimal system in order to find the book I wanted.
Derek I have to say that I have never seen a brake drum take off like that in all my years as a mechanic I’ve seen oxygen tanks blow through the wall, but never a drum rolling on the ground like that 🤣🤣🤣🤣🤣🤣🤣
I have. 77 El Camino. It put a new doggy door in the wall of my shop.
Why is this last nut so hard to get off?…BOOM
It really proves that the car was truly garage kept.
It also had never happened to me up until that point.
@@ViceGripGarage Derek I also thought it was funny when it happened you were smiling from ear to ear so o had to laugh 😂 🤣🤣🤣
I cant explain why I get so excited about these 80's Cadillacs. I just do. 🎉
Nothing beats VGG!
Thanks
I love the 2 door coupe .80's caddy almost bought one of those.
I really am glad for this part 2! If ever a car needed saving this caddy is it. We often get perplexed at technology. Thanks for not giving up!
On my 81 Coupe DeVille, the mechanic disconnected a wire that went to the transmission, then it ran perfectly on 8 cylinders all of the time. I never had a problem with that engine.
Gotta say, sittin here on an aussie Saturday afternoon enjoying a beer, and watching Derek work his magic, is a darn good day !
Ohh, and a fella did a pretty darn good job on the exhaust fitment there too !
Do you guys in Aus still have any old iron and v8 engines lying in junkyards? Here in my country malta have we absolutley nothing..if it wasn't for the British building an airstrip here during the war we wouldn't even have a drag strip.
@davidgalea6113 they're still lying around, although nowhere near as common these days, and in my experience, people tend to hang onto old stuff more now too
@@jonnothetrucker Brazilians have it worse, they outlawed new V8 cars at the end of the 70s.
I love that your whole family is involved. Wonderful. Perhaps the most family oriented car channel in all the world. Love you people.
When the engine is hot, the fan clutch is supposed to be locked or have limited slippage.
Many years ago I wad diagnosing a early 1990s GMC van with the 4.3L V6. It was a crank/no start condition. I went thru all of the basics, ignition, fuel, spark and air, everything checked out fine. Engine wound up flooding thru the diag. process, so I replaced the spark plugs, and changed the oil. Anywho, this vehicle wasn't O.B.D.II, I went home and thought about it, went back to work, dusted off the OBDI, pulled up live stream data and saw the coolant temp was stuck at -40. Well, I replaced the coolant temp sensor, and guess what, the van fired right up. Long story short, the van wad dumping too much fuel because the computer thought it was -40 out(it wasn't, it was summer at the time). So, yes, coolant temp sensor fault can cause a crank/no start
Had the same thing happen with a 89 celebrity, it was my grandma's car and she had trouble for 10 years or more with it stalling then wouldn't start, wait a while and it was fine. She took it to dealers and independent shops and nobody could figure out why. I had it at my house working on brakes and it decided not to start, I looked at live data and sure enough, -40. I changed the sensor and it was fine after that 😂
Wow this feller was SHOCKED when he seen just how clean inside this caddy actually is...😮
Those caddy hubs SUCK...GO back to the wired old mobile spoke hubs no one can see the Olds when it's rolling down the road 🛣️ anyway.
Definitely remember that. Index Cards and the Dewey Decimal System. I feel old now.
I'm with you brother!😢

Is that Dewey from "Huey, Dewey and Louie"? Figures. After all, their great uncle is Scrooge McDuck
It’s all on microfische
@@kellismith4329microfiche!
Haven't heard that in a few.
I had to learn how to use that system when the Army started putting their supply system on that.
Derek I hope you see this, I greatly appreciate all the hard work on your videos lately, but please next week take a breather and spend some quality time with your family.
Agreed
The look of pure joy on his face, priceless
Looks better with wire wheels... even if they is oldsmobile. loved the episode... I've spent many an hour behind a 80s GM dash... brings back memories
Well it's time to pull that old caddy out. And put a coyote under the hood be different put something under the hood other than an LS. Guys on half joking but. Just do something different. And then drive the wheels off that thing
Yep, the wire wheels were better.
I agree, Wire hub caps look much better on it.
I think the Oldsmobile wire caps look best. I am sure you can find Cadillac or GM logo center caps to swap out the Olds logo center caps.
This might be one of my favourite revivals its unique and really out of the box for a carburettor guy hope we see more stuff like this even though my heart is full of carburettors or i should say fuel make it hapeners keep it going big fella!
Ihave a 87 Monte Carlo SS 305 HO. Shes all original electrodigicals under the hood and runs like a top. I was one of those 80's Techs that had to repair all this madness, but once you got the hang of it there was no issue with what was going on. I'd be glad to help you out there Derek! I'll bring the cold snacks!👍
The box you pulled said Remanufactured on it.
Had a G.M sticker on it
@@danscott3880it had both Reman and GM on the same sticker 😎
that said remanufactured,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,someone had been there,,done that before,,,,,,,,,,,,,,,,,,,,@@danscott3880
Ain't that girl's first rodeo.
Your patience and mechanical knowledge is great. You have my sincerest admiration.
The muffler removal flashback😂😂 was gold!!!
That Caddy was a mistake in 81and STILL is!! The diesel Oldsmobile was too!!REST IN PEACE!🪦
Gee, it's funny how nowadays, that computer processing has caught up with the ideas from back then, that several makes now have modulated displacement engines that turn off some of the cylinders at various times to save gas.
Also, if you have one of these cars now, GM stuck with them til into the '90s-meaning the later PROMs give 30 percent more power than the car had when it was new. What other '80s car could get a factory provided chip that gave it 30 percent more ponies in its power barn?
Oh shit, the diesel Olds 88, grrrrr
@@slacker1597
The engine from HELL!👹🔥
Whose idea was this piece a 💩
yet Derek has managed to get both up and running, so...
They put that diesel in some of the Caddy's too. My neighbor had one. Good mileage but slower than a garbage truck and not very reliable.
This has by far been the best video VGG has done… had me rolling and knee slapping laughter! I watch this channel all the time and always learning from it! Thanks Derek!
I like the spoked hubs better !!
I remember the card catalog. We were digital by high school, but had both
Derek, my dad and I have been fans for many years. Thank you for all your family friendly content you produce, it is refreshing to watch when it seems like there is just so much filthy content now-a-days on youtube. Also, my dad and I are big jeep enthusiasts (like the older pre-2000s era). Any chance you may scoop up a an old cherokee, wagon, or wrangler? I think many on this channel would love to see a jeep of some sort. Thanks!
Derek. Thank you for what you do. I can't thank you enough. Words really don't convey.
To start off, I'm not a car person by any stretch. Maybe I'm a little sentimental.
I have an 81 EFI Sedan DeVille sitting in the shed at the farm that was left to me by my Granfather. He also left me an 80 f100 with a currently very tired 302 that I'm still driving today.
As a child one of the things that I remember most was how upset he was when my Dad told him he was going to give it a carb if he ever owned it. My Grandpa's response was "Then you never will, this is a part of history." He kept claiming how he would take it to a shop and get them to work on it. But it was always too expensive. I never knew this was a part of true automotive history that we'd never get back. I never paid attention.
He passed away in 2020 and I was left with the car. I have very little money and automotive knowledge, but a coworker of mine recommended your channel today at work. She said she and her husband started working on her Dad's old Dodge pickup and was telling me just how entertaining you were. Her exact words were 'He's that guy who is a teacher without knowing he's a teacher'. It's something the two of them have truly bonded on.
Anyway - her telling me about your channel, well, that got me into a discussion about this car. I had no idea it was this rare. Like I said, I'm not a car person. But I happened to bring up this car. I couldn't remember what kind of Cadillac it was until she showed me both of these videos later that evening.
And now here I am at 11 pm packing to take a trip up there to get my ol' paws under the hood and in the mitten box and see what trouble I can get into. Who else calls this a mitten box? You are truly one of a kind.
My coworker couldn't have been more right. You are the motivational speaker and teacher some of us didn't know we needed.
The three of us are going to try and get my Sedan DeVille running this weekend. It's a car, most of the world would say. But it's a part of history that needs to be kept alive. I hope you find a tired early 80s 302 in an f100 to rebuild and made as strong as it can be. You truly are an inspiration.
