I would LOVE that truck. I'm so glad someone is saving them. I'm also glad that a 4.3 v8 still exists. It's so disheartening to see that people just swap and scrap these engines because they are too stupid to fix them.
They are not at all hard to fix. I would say easier or about the same as a gas engine of the same size. Really all that they need is head studs and a water separator, if you want to go further than that I have built one as complex as copper head gaskets, turbo, splayed bolt main caps, half groove main bearings, dry sump oiling, piston oil squirters in the pan, built injection pump, pencil heads with pencil injectors with pintle lift adjustment all the way backed out. It makes 550 HP and revs to 6000 RPM, and with oil squirters the block is not at it's power limit, but rather the limit of the injection system. A fantastic engine with an undeserving bad reputation.
Ikr they they were super simple to fix. I don’t blame somebody for being intimidated trying to figure out this debacle of complication in today’s cars Especially since things are compact and hard to get to for example, on a lot of modern cars you have to drop the subframe and lower the engine just to get access to the alternator
It's good to see your posts again. I hope you didn't get rid of the Oldsmobile Dark Blue Regency....or your other cars. I always like to see you keep them humming and I admire your knowledge and understanding of those engines. Back when cars were so much more.
I had a 1981 Olds Delta 88 Royale Brougham 2-door coupe. First car when I turned 16. I loved that car. I wish I had it back. 😢 Hearing these is sweet music to my ears.
I had an 85 or 86 Chevrolet Chevrolet Celebrity 4.3 diesel company car which was not a bad car but it broke a few times and I did hear blown head gasket mentioned at least once. It had an excellent air conditioning..
Unbelievable! I’m living my dream through yours. I have owned a few. Still have an all original 79 Olds 98 with the D block. I was on the hunt for a 79 cutlass with the 4.3 manual transmission. I love all original GM odd ball cars. Thanks for posting.
Wonderful lineup!!! & Preservation. In your lineup it really goes to show how rare the c10 trucks are! Can't beat the cranking sound & Idle Clack of those engines.
Oh I miss those sounds so much. We had an 79 Caddy with that engine! All the neighborhood kids would come out and watch my dad leave when he drove it! You could hear it coming in from 2miles away. Dad was never able to sneak quietly home lol!
My first vehicle was a 1981 Pontiac Grand Prix with the 5.7 Diesel. Still the most comfortable vehicle I've ever sat in. Couldn't keep good cylinder heads on it, kept cracking them. I sure wish I would have kept it though, as I would have preserved it like you have done here. Very nice collection you have.
I love the Cadillac Seville. That rear end got my attention when they came out with that design. I had a late friend that purchased a black A few months before he passed. He was in New Mexico.
I was a beginning GM tech in late 1983, only V6 I saw was in a Buick Century with a broken crank, running on 4 cylinders. Worked on quite a few 5.7's and went to Gm's school for them. Never saw or even heard of the 4.3. 5.7 would last with a set of head gaskets around 60k or so and an upgraded injection pump. Overheat it and that was the end of the heads, head studs and better head gaskets sounds like the way to go with 22.5 to 1 compression stock. Nice.
I've always had a kind of fascination with the 350 Oldsmobile diesel engines neat that you have all the cars including the chevy Silverado amazing collection
What are 'pencil' heads? I special ordered a 1984 Olds Cutlass Supreme with the 5.7 liter diesel. At 82k, it started breaking head bolts. I maintained that car to specs, including using the proper oil (SAE 30). I can't believe that pickup has 100k on it!
This fantastic video is very unique in many ways. I'm not aware of another collection of operational Oldsmobile Diesel-powered vehicles like this one in the world! Also, this video serves as a great retro video for the Oldsmobile Diesel engine. (It would be an interesting retro video for GM.) I liked the fact that you displayed every iteration of the Oldsmobile Diesel produced (D block, DX block, 4.3 V8, and 4.3 V6). It was good to see water/fuel separators on these vehicles. GM should have installed those from the factory. The only thing that would have added to the video would be the blue 1981 Olds Regency that you have. However, I know that it was basically represented by the Buick Park Avenue. Do you still have that Regency? Thank you for posting!
I have a 1980 5.7 d. Cutlass. It always starts in less than a second even after sitting over the winter. I'm using it as a summer car. I need the vacuum parts that hoses are hooked up to at the throttle body and a cap for the washer fluid reservoir. Because of vacuum leaks my TH200 only shifts up after I lift of the gas pedal on high rpm's. No, it's not the modulator since it never had any. The Chevy pick-up sounded like it had a misaligned starter or something. Made that typical noise from the fly wheel/starting gear. Cool video. No one will ever duplicate it!
A friend has a 1979 Cadillac Brougham DeElegance diesel. Originally it was the service managers car special ordered with every option. In 1986 With only 25k miles the engine was replaced with a Target master DX block. Owner passed away in 1987 his wife kept it for 32 yrs in the garage. My friend bought it with only 27k miles. The new engine had only 2k miles on it. It’s a gorgeous car.
Very cool! I miss my 81 Delta 88 2 door. I bought it with 85K miles and blown head gaskets. A simple swap to a set of ARP racing head studs and a proper fuel/water separator and I put over 125K commuting miles on it in the early 2000s. Those 2 simple upgrades would have kept many of these on the road, especially the water separator. I spoke with an old GM mechanic years ago and he said he felt slugs of water being injected were the cause of most early gasket failures
I have a 82 delta 88 with the 350 diesel and I love it I got it dirt cheap at an auction non running and all I did was put batteries and a shot of either and it fired up and ran, now I’ve done glow plugs and it starts faster than any other vehicle on the property
Fantastic assortment you have there. I like the C10 especially. Years ago I converted several non running diesels to gas using the diesel short block and 403 heads. Vehicles were just not worth putting injectors and injector pumps in.
These got bad reputations but if not driven hard we’re great motors. Innovative in that they adapted the gas v8 into the v8 diesel. Had the fuel of the era been better these could’ve probably been much better. Notice how quiet they are when running on modern diesel fuel. That old high sulfur diesel was dirty, and stinky stuff. Thanks for sharing
Bring back memories of my dad's two GM diesels -78 or 79 Custom Cruiser and 81 Bonneville Safari. Question - to start do you need to pump the accelerator or anything like that?
I don't think it's recommended, but in our climate, it's sometimes needed on those extremely cold winter days. If it doesn't start easily on its own, it's the glow plugs or controller likely need to be fixed.
Depressing the accelerator once while waiting for the glow plugs to go off activated a cold start advance solenoid. Pumping the accelerator on a mechanical Diesel doesn't push more fuel like it does on a carbureted engine.
@@randyrankin589 To clarify, fast idle was dependent on the engine temperature, as was the glow plug preheating cycle, controlled by the same engine temp sensor. The fast idle speed for cold starts and engine warm-up normally activated without pressing the accelerator pedal first. However, If the fast idle solenoid was sticky or weak, the solenoid plunger may not be able to place the injection pump to fast idle without pressing the accelerator pedal. With the fast idle solenoid energized, the solenoid coil will hold the plunger at full stroke position regardless.
Your video is one of the only ones I could find that featured the RARE '79 Olds 261 4.3 DIESEL. Definitely not many were made and even fewer are left. Did these have the head bolt issues of the early 350 diesels? Just curious. Not too much info on them since they were only made for such a short amount of time.
Very impressive line up! How did the gm truck get the olds diesel. I have seen a couple before. But did you just tick off a box when ordering your truck or did you have to pull some stings with Chevy
Hi, I posted the other day, not sure if it actually posted or got deleted? I was saying Im looking for one of these old diesel cars a 1985 Toronado or Eldorado or even the 4.3 Cutlass Ciera. Im in Houston. Any leads let me know, thanks. I'll post a link to my website to make contacting me easier if that is Okay with you?
My Mom has the Mayor of Syracuse's Mothers Cadillac 1984 Sedan Deville Gold metallic paint, 350 Oldsmobile Diesel it had about 238,000 miles before detonation snapped the wrist pin clear off ! ended up finding a 1970 Oldsmobile 350 Rocket engine out of Texas for a couple grand all rebuilt, car is still running strong today, they just don't make them like they used to because people hold on to them ! and they are safer vehicles! price keeps going up on these awesome classics and Antiques. Thanks for showing off your cool collection, God Bless.
I've just noticed you have no Pontiac with the Oldsmobile 350 Diesel, and to be honest i haven't seen many Pontiac's with the 350 Diesel only one i can recall was 15 years ago may have been a Grand Prix, these vehicles are pretty rare to begin with low production numbers, cool stuff.
Love them old hybrids diesel's 30to 40 MPG,s all day in full size cars news cars can't even do it in small packages and computers the EPA knew that that's why they hate diesel's my 83 k20 suburban with 6.2 diesel kills it on MPG 27 all day
Can you tell me which years and engines to watch out for because I am looking to purchase. I am scared to because everyone just slams Diesel engines in general not realizing that diesel done right is better than gas in certain vehicles
Look for 82 or newer, 4.3 V6 or 5.7 V8. 83-85 is even better, they had worked out all the issues by then. 85 is the final year, they had a factory water separator, one should be added on any of the pre-85 models.
All the Olds designed diesels performed the best and ran more reliably if the car was driven normally and not pampered. Using the available engine torque during acceleration was the preferred driving style.
I would LOVE that truck. I'm so glad someone is saving them. I'm also glad that a 4.3 v8 still exists. It's so disheartening to see that people just swap and scrap these engines because they are too stupid to fix them.
More or less don't wanna learn, and keep it simple besides automatically believing the rumors and myths.
They are not at all hard to fix. I would say easier or about the same as a gas engine of the same size.

I can't thank you enough for posting this video, and for keeping these vehicles alive. What a glorious sound!
Sounds so good from a distance. Like a River rushing over stones, so goes the diesels of the Oldsmobile.
It's good to see your posts again.
I hope you didn't get rid of the Oldsmobile Dark Blue Regency....or your other cars.
I always like to see you keep them humming and I admire your knowledge and understanding of those engines. Back when cars were so much more.
That 79 4.3 V8 is probably only like 1 of 10 left in the world that still runs!!
We had a 81 Delta 88 Royale Brougham. Hauled the family all over the country and would get 35 mph. Certainly enjoyed that ride.
I had a 1981 Olds Delta 88 Royale Brougham 2-door coupe. First car when I turned 16. I loved that car.
I wish I had it back. 😢 Hearing these is sweet music to my ears.
I'm confident this is going to go viral and be used as a reference for those who deny their existence lol. Thanks!
That 4.3 260 V8 is a unicorn for sure.
Fitting quality cylinder head studs to replace the weak factory fitted bolts practically eliminated head gasket failures.
I had an 85 or 86 Chevrolet Chevrolet Celebrity 4.3 diesel company car which was not a bad car but it broke a few times and I did hear blown head gasket mentioned at least once.
It had an excellent air conditioning..
cool collection! All you need now is a manual transmission 79 260 Cutlass and a RWD 4.3 V6
This is awesome. I have an 84 cutlass supreme 2 door RWD with the 4.3 V6 diesel.
I'm impressed really, it's so nice to see so many cars all gathered together with one of my favorite Oldsmobile engine in them.
Unbelievable! I’m living my dream through yours. I have owned a few. Still have an all original 79 Olds 98 with the D block. I was on the hunt for a 79 cutlass with the 4.3 manual transmission. I love all original GM odd ball cars. Thanks for posting.
I have been looking for one of those for years at this point. They also made a Pontiac 6000 STE with a 4.3 V6 and manual transmission.
Amazing
Wonderful lineup!!! & Preservation. In your lineup it really goes to show how rare the c10 trucks are! Can't beat the cranking sound & Idle Clack of those engines.

Thats awesome! I cant imagine theres too many of those 4.3 v6 diesels out there!
Glad to see you back. That’s one nice set of rides you got there!
I love the Custom Cruiser. I had an 81 Caprice Wagon Diesel. 28 mpg
The water separator really helped these engines I heard.
I've always had a kind of fascination with the 350 Oldsmobile diesel engines neat that you have all the cars including the chevy Silverado amazing collection
What a unique collection! I also love the fact you have two gmc front-drive motorhomes! Great collection!
That's a whole Lotta rattle in one showing! I love it!
Absolutely amazing collection !!! Great to hear those Olds diesel’s. Thank You for sharing.
Quite the collection thank you for posting
Awesome lineup!! I never knew there was a 6-cyl and 8-cyl 4.3L!! Where did you find all these? That is the first diesel half-ton truck, no?
You read my mind, I was thinking that I know about the 260 v8, but a v6??
The LeSabre probably the most dependable of that group. They worked out the DX bugs by then.
Quite a collection! Those are keepers !
Good to see you back!! DX parade. Keep them coming. Do an update. Video in landscape is even better.
And, don't THINK we don't see those GMC motorhomes. lol
Thanks for sharing your beautiful collection with us!
That's a great collection. Keep saving them!
Awesome collection! So many rare cars. And that wagon!

This is so cool, I had no idea they made diesels out of 4.3s as well! Very nice collection, they're all so clean.
I think its more like they made a 4.3 diesel not made a diesel out of a 4.3 wouldn't you agree?
Absolutely fantastic! Thank you for sharing and for keeping these beauties on the road!
It's very remarkable that these vehicles survived to this day.
I love this ! Thanks for sharing.
Amazing collection! Thanks for sharing with us.

Life changing collection!!! My life dream!!!!
Had a 81 delta 88 very good car,Even in cold Norway
Fantastic assortment you have there. I like the C10 especially. Years ago I converted several non running diesels to gas using the diesel short block and 403 heads. Vehicles were just not worth putting injectors and injector pumps in.
Wow, that fills my heart with pure joy. 😊
Beautiful collection
Love it !! What happened to the beautiful( 82 I think) olds 98 regency ??
Seen you yesterday in East Texas in the lesabre beautiful car
These got bad reputations but if not driven hard we’re great motors. Innovative in that they adapted the gas v8 into the v8 diesel. Had the fuel of the era been better these could’ve probably been much better. Notice how quiet they are when running on modern diesel fuel. That old high sulfur diesel was dirty, and stinky stuff. Thanks for sharing
And if they added water separators from the get-go
this is such a cool video thanks for sharing
Been waiting for this awesome
Can't believe you have one of the 4.3 V8's. First car was a 79 Delta 88.....I learned to do head gaskets...HaHa.
Great that's your back. Where did the 85 Cutlass The Olds 98 sedan and coupe and 85 Buick Collectors Edition Go.
Good to see you Mr 81’olds
This man loves being stranded on the side of the road
This is super cool.
Old skool classic Buick/Chevrolet and Oldsmobile V8 Diesel engine

Where do you find these diesels? I have tried to find one to buy and can't find them at a decent price.
Very cool line up looking back as bad as rap these engines got a person can look back they are not as bad as the crap that GM is producing today
Love Love Love!!! But no Ninety Eight Regency Brougham or a Delta 88 Royale Brougham?
Word of warning though if you use the same amount of oil as did the factory the engine won't last.
Thank you!!
How is the fuel mileage on all those good old diesels? Would be interesting to know!
High 20’s to 30’s is not uncommon from what I’ve heard.
This is a cool video but question why none of those engines are never steam cleaned?

GM offered them in the whole line up, even though the original branding & engine developed out of the Oldsmobile group.
@@lanemcreynolds9894 I think I saw a video of a G van with one too?
Is the any of the Buick’s still available
LeSaber was a great car
Way cool
How any do you have? Your videos have some of the same ones, but not all together. Do you still have the Delta 88 you started with? 😁

My question - how reliable were any or all of these? Was the poor reputation accurate?
Do u have any caprice or impala diesels or even a chevette?
I have a 1982 Cadillac Coupe DeVille 5.7L diesel and needs injection pump rebuild who your shop??
Just saw a 82 regal with a 4.3 ?? On fb
No 5.7 diesel?
Wow !

Is any of your diesel for sale?

The magnificent 7❤😂
These where all decent engines if you didnt try and drive them like a gas engine , and keep good fuel and keep the water out of the fuel
All the Olds designed diesels performed the best and ran more reliably if the car was driven normally and not pampered. Using the available engine torque during acceleration was the preferred driving style.
Whats "pencil heads"?
