@@johncajson You're welcome. It took some time to get the timing right on each chapter of the video but it was worth it for people who are learning about the family of Duramax Diesel engines and how it has evolved since the beginning from the LB7 to the L5P.
😂thanks
@@Jeffrey-yx6gt h my
This nigga really calling them chapters😭😭
2007 LBZ here original owner and as I sit here watching this video I’m currently at 399,850 miles. Never touched the injectors, turbo or trans never a single issue. I LOVE LOVE my Duramax I do need to replace the thermostats right now. Other than standard maintenance and tires the truck is untouched. I do have transgo kit, PPE tune and turbo back MBRP..
2006 LLY owner here! Love the truck.. keep up the great work man, my truck wouldn’t be what it is without you.
Thanks
Bought my 05 lly 18 months ago and have it at 896hp 1573ft lbs of torque. Thanks for all the install vids 👍
Picking up an 05 LLY this weekend, was an grandpa grocery truck, with 70k on it... one owner, can’t wait man. Really appreciate you putting your knowledge out for us all.
I got my LLY in 2014 with 76k on it. Still drive it everyday with 220k on it still runs great. I had to replace the water pump around 170k and the hydroboost around the same time, both leaked on me but hydroboost was easy to change, the water pump a little more involved but do-able for the skilled DIYer.
T
Ll. K jk k. I’ll ok nbirthday
I had a '07 and put 380,000 on it. The engine and Allison were still running great. Only thing that ever broke engine wise was fuel filter housing. Transfer case, rear end, and axles were another story.
went thru 2 front ends on my 07.. But the rest was great
I bought a 2005 3500 Silverado in Oct/2017. It has 203000 miles.
It runs really great and I love the power.
Thanks for the info.
I’ve had Cummins trucks for a couple years. My grandpa got an L5P I pulled with it one time. Sold my truck and bought a new L5P In October she has right over 30k miles on it (I hotshot) and not a single hicup. I love this truck.
Just got a l5p to hotshot what Cummins did you used to have
Just bought my first Diesel a week ago. After slight research picked the Duramax 6.6 over Cummins and Ford 7.3 and went shopping for a used one. Bought a 2006 Chevy Silverado 2500HD and it’s the LLY version I learned after looking at the VIN. Super excited I bought this truck. Been learning a lot this past week about them. Great info in the video.
Thanks ✅
Just bought a 2005 LLY with 18,500 original miles... I just traded up from a 2011 civic. I love this truck.
Thanks for doing this. I’ve been building the duramax for 18 years and dam proud of what I do. Love hearing the positive feed back about our product. Watched this while working at Dmax!!!!
+Timothy Thompson are you part of the team that designed the engine as well? But either way very honored to meet you sir
Ha! This is AWESOME!!! Thank You for Helping to produce the Baddest Diesel on the Planet! (IMHO)
Truck Master no the engineering is done in Japan through izusu we have some engineers that test different ideas like a twin compound turbo duramax. It didn’t have the reliability needed
+Timothy Thompson I wish I had your job sounds Enjoyable
Makes two of us watching this. I’ve only been there for the L5P though. But hoping to be here for the long haul.
Mann! Only if we lived in the same vicinity, I would love to pick your brain, Thank you for all you do. You seem so humble and willing to teach and share your knowledge with patience and without judgments. It’s channels like yours and BackRoadDiesel that make it easy to learn. I’m mechanically inclined and have always liked Chevy but new to the duramax world. You guys make it easy for those of us who want to learn but don’t want to mess up something so expensive. Thank you again.
Love my 07 LBZ!!
I just picked up a 06 lly down here in TX.
143,000 miles all stock.
Ready to start tricking it out.
That’s awesome
Just picked up an LBZ with 87k miles all stock 3 days ago. I’m ready to start fixing mine up as well👍🏻
Aliminy damn it’s so rare to find one with that low of miles
That's a LBZ brother
LuvJoeBacon there are 06 lly’s
Great video. I'm 62 yrs young and I'm looking at my first Diesel truck, which I know nothing about. It's an '05 2500 HD. It has 113k on it with full delete, 5 position switch, 5" exhaust, K&N filter and now I know what else to ask about. I want it to pull a travel trailer. Your video was very informative, now I know it's an LLY
+RFS1955 that’s great and good luck to you
Bought a 2012 Cummins brand new, just sold it last year with 50k miles. Picked up a 07 lbz with 200k miles awesome truck.
+panco deiga wow that’s a big changes but I would trade a 6.7l for a LBZ
Thank you for putting all this info together! One common theme I notice is that each year there is an incremental go increase, but it sounds like you say with a delete tune intake/exhaust you “could” reach the numbers that a few model years later puts out.
Great video!!
Had wanted to get the 2007 LBZ when looking to pick up a diesel. I liked the OBS over the NBS. No luck whatsoever in my area unless you wanted to travel several 100 miles to look at one, and then they were pretty high priced. I was driving an 05 3/4 ton gasser that looked just like the one you have now. Found a 07 NBS with LMM that had just been traded in on a brand new Silverado. The truck was local, serviced local, and very well taken care of. Price point was in my range. Still need to take care of some things on it, but I was extremely satisfied with the performance of the diesel. So I guess I also represent the Love My Motor group! Thanks for the history lesson, very interesting!
I have a 2006 LLY. 218,000km. I got it from my dad just recently. He used it as a grocery getter in a small town. I was pondering upgrading it to a 2014 Denali LML (I love that style) however your video has me second guessing. The truck is still 100% stock but I’d like to add a tune and the pump rub fix very soon. Thanks for the information.
Thank you for this explanation. I'm new in the DURAMAX family and I really learn a lot with your videos. Just because I didn't know nothing about DURAMAX I bought a 2005 so it must be an LLY. THANK YOU!!! For your videos for us to learn about.
+Alberto Fernando Ruiz Hernandez congrats on the lly take it easy man
So I have watched this video at least 3 times.... and I broke down and picked me up a new to me 2013 sierra denali LML today. this is prolly the video that helped pick which one i wanted to go with. So thank you @truckmaster
That’s awesome!
ive owned a 2005 lb7 with 230k km heavy hauling , had edge tuner and blew injectors . paid 8k for full engine/ front/rear end rebuild .. still own 2005 duramax , just found a 2007 full load LBZ with 220k built to perfection older fellow owned rust free frame off undercoated . LOVE DIESELS btw im from southern alberta where we actually use our trucks !!!
Lucky find, it’s hard finding those clean classic body style duramax’s up here in Canada. I’m from Alberta aswell and been dying to look for a clean low mileage truck but everyone is selling theirs for basically the cost of a 2015
I have the L5P and it came out in 2017...best diesel ever..
l5p is a good engine but it’s also overrated
Also the weakest diesel on the market. It's torque output is hilariously low
Easy way to confirm you have a actual LBZ is the 8th digit in the VIN is “D”. Also I think the LBZ has 7 hole injectors. Great info for someone looking for a Duramax powered truck👍🏻
5280 Jeff this is helpful for me cuz i want a 2006 lbz
+5280 Jeff I didn’t know that thanks
It is possible to have an 06 lly that is an lbz still, despite an lly vin.
DaJokrz That’s true but will not have the factory tune of 360hp and 650ftlbs or torque.
5280 Jeff correct, but hard parts are identical. I have an 06 lbz and an 06 lly. There was a difference in head gaskets, one was riveted and one was pinch welded i believe. The tuning difference was simply due to GM waiting on the emissions to be passed on the lbz. Its easy enough to get the dealer to put the lbz tune on the 06 lly however, so the tuning is kinda a moot point.
Kudos on the comparisons. Very informative.
I just got a unicorn 07 LBZ last month. 70K miles one owner, garage kept, long box , crew cab, 4x4, snug lid paint matched, all options, leather, even DVD player in rear with wireless headsets! It took me 2 years to find it, and I flew NY > OR and drove it 3.3k miles home. It’s incredible, I’ll own it until I die!
Truckmaster you have done it again. I think you did a great job explaining things, especially for the guys looking at getting into our platform. Nothing new as a fellow LBZ owner. But good info. I think the only thing you lacked was the 8th digit vin codes for engine designation of all the models. Not trying to steal the show but just trying to add .
LB7 -1 (Fixed vane sound, awesome)
LLY- 2 (06 Exception,mechanically LBZ)
LBZ-D (hotrod they say, mine was a dog. stock)
LMM- 6 and 9 (way to garbage up an lbz with more emissions crap )
LML- too broke to care
L5P- Why are we still talking about this, all you want is an LBZ anyway
I have a 2006 silverado with the lly (a detuned lbz). 210k miles and runs like new 💪
Love your channel man. I’ve got an LBZ. through my job I’ve drove all the new diesels.... with at least 16-20,000 pounds behind em. nothing compares to a LBZ. I base my opinion on stock trucks. The LBZ just always has more to give it was the most power you could get with no emissions. And the potential of aftermarket power is in ending...
Would you recommend a lbz dually over a lml dually for towing weekly and simple performance mods
I just got an 05 lly with 158,000 miles. The only mods are an.s&d air intake and 4 inch exhaust pipe.. this truck is very clean. No rust. Interior is perfect. I got it from a 93 yr old man who got it new in 05. The body and paint are just about perfect. No dents or bad clear coat. It's my first diesel. In Oregon here they range from 15 to 20k. I paid 17k. I sold my 2013 f-150 to get it. I recently got a toy hauler and needed a 3/4 ton. This was the nicest one in my budget.
One of THE GREATEST videos I have ever had the pleasure of listening to ( YES, the 'rambling is one of the things that make it great !) Now, I WOULD LOVE LOVE LOVE AN IDENTICAL VIDEO FOR THE GENERATIONS OF CUMMINS AND POWERSTROKE !!!
This is the video that got me started. Cool cause its an older video, but never did i think id get this far, and never thought we would actually meet. That was really cool.
Glad I found your videos - ive never been a gear head or yet alone understood diff. Engine types - now that I'm hauling a trailer, I'm realizing I should of been. Your videos have helped fill in gaps that other channels dont seem to touch on . thanks for the great content
Thanks Dave I appreciate that
Still going back and watching your older videos Josh! Thank you for sharing your knowledge! Keep on keeping on brother!
Very informative. I have a 08 LMM . I believe you stated had the emissions box on passenger side. FYI mine doesn’t. I think 08 was the last year before those emission boxes came into play.
I own a 2011 (LML) GMC 3500HD, that we use for full-time truck camper hauling, and utility trailer towing. The only issue we've had, has been a NOX sensor problem in the first year, and the DEF system, which, according to a service manager we spoke to, was the worst design ever due to the heating plates in the tank. Deleted it, and no problems since. Love the truck, 10 years, 100,000 miles, still runs like new. I hope it lasts as long as some others in this forum.
Thanks for the info , Can buy good used Dmax for 20,000 , but to get the same power and creature comforts from a dodge will cost another 6-8,000.
Just looking back at some of your older videos and I have a 06 duramax with the lly after checking my vin number. Thanks for the info. Bought the truck new in September of 05 and still love it. 106,000 miles and has been trouble free except batteries and changing filters and oil. Love the channel
I really like my 2006 LLY. it woke up from stock after a straight 4 inch exhaust swap.honestly my only complaint is keeping tires on it even after i put an economy tune on it.
I drive 2009 LMM DURAMAX , I was told to delete the particulate filter system because the DPF caused diesel gas to be back flushed into the engine oil ! I was told that this could cost me 100,000 miles off the life of the engine ! So I had the DPF taken off and replaced the exhaust and had the engine tuned using the factory computer chip ! I have 145,000 miles and use it to tow my 5th wheel every now and then ! Otherwise I baby it with timely oil changes and allison 6 spd transmission fluid exchange every 35,000 miles and external filter exchanges along with the gas filter changes ! I get about 20 mph pulling my camper on flat road, no wind at 65 mph !! Awesome fuel milage about 22.5 mph with out the camper ! Plenty of power to do anything I want ( engine tuning )
Aye! Bertrand850 and I representing LLY!!
Great video as always bud!
Nice video, the comparison was awesome. We bought a used 2004 (lly ) in 2008. The truck was traded in from a local dairy to our local garage (formerly a GM dealership that my family has used since before me and I'm 51 ) and had 107,000 miles ( newest vehicle I've ever bought, age wise). Now truck has 300,000 miles, new transmission and transfer case at 293,000 miles ($5,500, done at a really good performance transmission shop). Luckily transmission quit with the trailer empty. Transmission shop said they never heard of an allison trans go that many miles. They usually only last 150 - 200,000 miles. Our shop said they never heard of an allison trans go bad. Except one that the tail shaft bearing went out and people just kept driving it on a farm until metal from bearing destroyed the transmission. Our duramax is a GMC 2500hd, 4x4, four door, short bed all stock. My old baby (currently not running an no time without dust, dirt and wind to fix ) is a 1969 chevy 3/4 ton four wheel drive. It has 4" of lift, 35" tires, sm465 4 speed manual transmission, np205 transfer case ( I installed this along with a disc brake front dana 44 axle) and a professionally rebuilt 454 with 375 - 400 horsepower (I shoehorned the engine in myself. This body style only had big blocks in two wheel drives and it sits ahead two or three inches ). Towing, the duramax is comparable. Duramax has almost double the fuel mileage but sucks off road and feeding in the pasture. Duramax is too low, too expensive to lift and doesn't turn. But we'll keep it forever like everything else. Duramax also has A.C. which is nice because I work part of my day in a 34 degree cold box. Anyway, our current issue is the ficm. Twice before we had trouble with the injector harness, "they said" #2 and #7. First time was on a trip to Oregon, second time our local shop fixed it. This time our local shop said I got the ficm wet. $750 for a reman part, $1150 total. Truck quit when we got home ( 10 miles away). Shop said limp it back in. It took 45 minutes at 14 mph. The day the truck originally malfunctioned, it was raining and dark at 3:30 a.m. I hit some big puddles but truck ran fine until I was leaving work. I drove through another puddle slowly ( In the early morning I was going faster). Five minutes later the truck shut down. Two days before this, I fueled up at Chevron. After about 20 miles fuel guage read 3/4 and about 30 miles, to and from work, guage read 1/2. When truck went to limp mode fuel guage read empty. I limped to Chevron and put in 8 gallons and guage still read empty. Shop said fuel guage is a different problem. Fuel guage worked correctly on trip home after repair but back to empty while limping back to the shop, in the dark at 5:00 p.m. Truck is still in the shop. Any advice, ideas, help would be greatly appreciated. Thank you for your videos.
I've got the same fuel gauge problem on my 06 LLY it reads about 1/4 tank low all the time. Did you ever figure out the problem
I was unsure of what dirtymax to get. All of this going over has lead me to go with a lbz. Thanks so much buddy
Thank you for your service, loving this Country and your beautiful family. I'm looking forward to getting a duramax as my next truck for towing and you have been a great help in your knowledge!!
The next mod u should add is a coolant filtration (good for keeping your heater core clean, and keeping coolant clean as well as keeping the pH balanced and stop the coolant from eating the head gaskets)
Theone Theonly how do you install it? And how often do you change it?I'm really interested!
I've been considering one for a long time. I recently changed the water pump and noticed the housing was slightly eaten away at the turn point. I'm pretty sure that was from the crappy well water I used at the first coolant change, so a filter would have most likely prevented it.
New to the channel here, just picked up an 06 LBZ with 104,000 on it! Stoked.
Awesome video. Thanks man!
And love the M16 disassembly chart in the background!!!
I drive a Ford I don’t even know why I’m watching this lmao.
Thanks either way 👍
@@TruckMaster great video man always fun learning about diesels 🤙🏽
I drove a Ford too until we took my brothers lbz to pick up a Bronco really impressed me so I found an lly I love it still drive my Ford too
Damn!! I was so happy when I heard you say no EGR on the LB7. I have an 04 LB7 with 290k miles. I love my truck and I get a lot of my info from watching all these channels. Well I try to understand more about my truck. It sucked when I read the comment from the guy that said the trucks from Cali have EGR's. I remember I had a code once that had something to do with the EGR. DAMN!!! I wish I knew more and I wish I lived closer to you too!! I would like to delete the EGR and tune mine.I love your channel.
Well I got 2003 chevy 2500 ; I'm glad doesn't have egr
I also have a 03 lb7 with no egr. It has 270k miles on it. Been a great truck! It's my baby lol.
I'm Agee with you ; love my Truck as well; I wish can share a pic but it is black in color; bo rust ;
Jacki Goddard I wish we can share a pic of my truck ; or talk. More often about you experience with your truck
If you do let me know please
I have an 04 LLY that I ordered with the power package that included the Allison Transmission and the locking rear diff
How did you find out that ur 04 is a lly???
The LBZs are like the holly grail of the Duramaxs at least that's what everybody says haha great videos man keep up the good content
+TERMINATOR 6.6 great input thanks man
Agree if you are buying a new truck, but in buying a used wouldn't an 06 LLY have seen less abuse with the same potential?
@@rick8676 Any 06 Duramax is a LBZ. Early 06 models (Like mine) is a LBZ but has a LLY tune because chevy didn't have a LBZ Tune that was ready for emissions testing. You can fix this by getting a tuner and put the stock LBZ tune
@DastardlyWaffle agree, 08 lmm 4" straight pipe and its just as strong as my cumins 5.9
@@luvjoebacon2915 it's amazing how many people don't know that one fact. That being said, I love my lly. Lml was ok, but I came back to Lly. She has my ❤.
I think you did a great job. Just enough info without boring anyone. I know that this video could be hours long. I will be rewatching it again
+Dan Soderholm that’s good to know thanks man
I bought a ‘02 with 124,000 miles for $11,000. Love my truck. I did change out the injectors with Sinister.
I have an L5P it’s an awesome engine. My first diesel that I’ve owned. Runs better then the diesels in my fire trucks...lol. Great channel love watching your clips..
Pops own 3 Dmax's 04 3500 dually , 06 3500 dually, 11 2500 denali. Bought the 04 with about 120k miles (still running strong daily work truck at 225k miles.) 06 he bought brand new for work as well personal use just hit 100k miles. And 2011 denali lifted 2500 bought with 45k miles off a friend now has 70k miles. All are amazing engines havent been let down from any of them. Duramax on top man
I have a 2006 lly with 378k miles and it still runs strong. No complaints about it.
Your duramax is the coolest style period. They just look tough
EGR is added to cool exhaust to reduce NOx emissions. Hotter the burn mor NOx less particulate. The cooler you get the reverse.
Egr isn’t used to “reburn”. Cooled exhaust is an inert gas that is put into the combustion chamber to lower combustion temperature and that reduces nox. Nitrogen oxide. Not to be confused with nos, that’s nitrous oxide. One is a deadly pollutant that will kill you if you breath enough of it in, and the other is laughing gas.
blake dymond lol guess I wasn't the only one irritated by the comment he made
@DastardlyWaffle Not to mention that the computer knows what proportion of exhaust gasses are entering the intake stream (assuming your valve and sensors are working correctly) and adjusts the fuel requirement accordingly. Assuming all other intake sensors are working correctly ( MAF to intake manifold pressure) you will use less fuel and make the same power. Remember, almost all emission controls function below 1100 rpm and most of us are towing and making power above that number. Keep on making classy comments full of knowledge brother!
Great video as always man, I think your explanations of the differences between each motor’s pros and cons was fantastic... I have an LMM in Texas and I am thinking about doing the EGR delete and other upgrades but I have to worry about the emissions and finding a place that would pass the truck when it the time comes to do my inspection.
If you have any ideas about how to be able to do it and have it still pass the emission test legally let me know.
Brother has an 05’ LLY. Dad has a 12’ LML. I have an 02’ 8.1 gasser. Love all 3.
hey ive been watching you for i little bit love your content just picked up a stock 2007 extended cab LBZ 4X4 with 284,000 miles down here in florida got it for 4k very clean truck just pulled the heads for blown gaskets and had them machined and studed the truck did up pipes and went with an sdp y bridge kit ,did a pcv reroute took the time and powdercoated everything too ! ive worked on diesels but never a dmax and without your videos it would have taken me longer lol i appriciate your hard work keep it up! lift pump and exhaust is next !
Great vid, answered a lot of questions I had. I'm not a guy who doesn't play favorites, I love all machines. I have owned a lot of machines, be it motorcycle, boat, truck, Rv, off road side by sides etc. I started wrenching back in 1965 on my first motorcycle. My first car was a 1958 Chevy Nomad which was my families car with 260k on the clock. It had the 348, I started work on it in 1967 to get it running after sitting for a year until I got my drivers lic. After it died I went to a 1956 short bed Chevy 235 6 banger. Though the years I can't count how many cars trucks I have owned. I've owned gas trucks of every brand just about. In 2000 I bought a brand new off the floor F350 7.3. Then the next diesel was an 05 ram Cummins. Then followed by two more 7.3's which I love to work on. I decided I need a 3500 dually to haul the weight I am now towing. I did a lot of research because I don't have a ton of money to throw at a big truck that is capable of what I need. So I settled on a beautiful 2006 Duramax dually with 159k, the guy I bought it from was amazing, he had every receipt for everything that had ever been done to the truck. To make a long story longer, he did things like EFI tune, 5 Inch turbo back stainless exhaust, rebuilt transmission with heavy duty parts for the tune, and so much more. But what I was getting at it turns out it's a LBZ. Thanks for help understanding the Duramax as I am now fan.
I have a 2006 GMC Sierra lly, but I am tuned. Absolutely love this truck
The LB7 is the strongest Duramax of all the years despite the injector issues. Injectors can be changed out on the LB7 in a days time. Instead of buying rebuilt injectors, have yours rebuilt and save half your money. The common issue with these injectors was cracked bodies. Bosch fixed that. The second issue is the VOC nozzles. Now they are making SAC nozzles and are showing great success in longevity.
+chris chrystal great input thanks
Hello I have a 03
SAC 45’s work great
Hi Chris nice information on the lb7 I have an 02 injectors replaced at a hundred k are there any precautions that I should take to make the engine last it has a hundred and thirty-four thousand miles on it thank you Joe Connecticut
Run a diesel additive to keep your nozzles clean, other than that there’s really nothing you can do
I own an 03 LB7 and I had a recal on the injectors which was issued by Chevrolet. They took my truck in and replaced all 8 injectors under warranty. The issue was eroded ball seats of the injectors. Had that done in 05 still running strong today. No lift pumps just the main fuel filter changed every 30k. LB7 for the ultimate HP and least amount of issues!
Thanks so much for all the information. Had an LYL and now own the L5P and this explains enough information to fill in the holes of what I know already. So thanks again for the information and details.
Thank you very much. Im new to Duramax and trying to decide on what one I want and can afford. Now I know the differences in all of them.
i just acquired a LBZ this year, first ever diesel. So much to learn.
I agree!! But the power is AWESOME!! And it whistles at the ladies!! Lol!
I have a 2005 lly with 372,000 miles. Most reliable truck i have ever owned
+Aaron Hartland that’s awesome
FINALLY...... Now I understand & know my "ABC's" of the DMax World!!! Thank You for making & sharing this, Sir.
+Phil G. No worries hope it wasn’t to confusing
Not at all...... Good Stuff man!
Nice AR diagram. Have 05 lly with 359 thousand miles probably one of the best years chevy ever made good reliable rig. Just bought 2011 lml very nice truck. If you have the money duramax is where it's at for sure 👍 love your vids.
Thank U for your teachings....... I learned a lot.... I have a 2002 LB7..... 166K miles, stock injectors so far....
I hope u do a story on the new 3.0 l inline 6 cyl in the near future I know the engine has only been out for a few years. I have a 2021 duramax 1500 Silverado
I'll save you the trouble. The failure point is a rubber belt that drives the oil pump. The inspection is at 150,000 miles and costs that is if you pay someone is $1,000. Stupidest design flaw. They could have made it a chain driven.
Dude !!! Another great vid man i have been living under a rock good stuff man shout out from los angeles
Thanks 👍👍
Great video! I've had my lb7 for a few months. 250k and runs like a charm. Injectors are going bad, front end rebuild just shipped and the transfer case needs rebuilt but I love it!
+Ben Drinkin that’s great keep her ticking!
Ijust recently purchased an 06.5 Lbz and I absolutely love it. has 157k and she is deleted and has a new exhaust system. Im considering getting a lift pump because these are known fro the fuel starvation issues. Not really sure what else i should do to make her last as long as I want her too. Feel free to give some pointers and if I should get any more upgrades to maker her last as long 900k
First truck was a lb7. Put 600k miles on that truck. Two injector jobs, stock trans, DB stage 2 turbo and ppe tuning. Was a beast. Sold that truck for 10k with 600k miles n he is still driving it today.
Own 2 lbz, GMC Sierra and Chevy Silverado . Both are tricked out with efi live tuning n 30 over injectors. 64mm turbos coming in February.
I have a 06 kodiak Ily but was disappointed it didn’t have the 6sp. Looks like a 2,100.00 upgrade. Great channel, just subscribed thanks for the great info!
Good video, agree with most of it. A good part B would be common failures for each.
Appreciate the detailed explanation of all the different models!
Proud owner of L5P...love it!!
👍
I have a 2008 Chevrolet Silverado duramax 3500 dually with 185k miles bone stock in California so far so good😲
I bought my 2005 Silverado 3500 Jan. 2019 with 39,500 miles. It still had the original tires. I traded my 2012 Ford F250 6.7 completely deleted and new turbo even swap. After all the BS dealing with the Ford I decided to switch. This 2005 dually was cherry. LT package with a in the headliner DVD player. The previous owners bought it and put a cab over camper in it and only used it to go camping.
I remember when I first heard about General Motors trucks being offered with the Duramax. I was more curious than anything else. I'd heard of the Cummins Diesel as offered on the Dodge Ram truck, and the Powerstroke Diesel for Ford. But Duramax Diesel? At that point, I was like "What's that?"
LB7 FTW! We the OG’s!! Gotta make that high power!💪🏼💪🏼💪🏼
Just doing injectors on our LB7 are a pain 😂
Hey, I'm thinking of buying a lb7, could I get some advice on a few things?
@@brandonb5735 what do you need to know? I bought mine in febuary of 18 with 148K on it for 13k ended up putting injectors in it at 155K but now its a really reliable truck Id tow anything across the country without hesitation. if you buy an lb7 see if the injectors have been done and make sure their is paper work! also see if you can hook a cts monitor up to it and check the balance rates that's a good way to tell if they are going out also look for blue or white smoke coming out of the exhaust. check the top radiator hose make sure its plyable if you cant squeeze it after its been ran then it has bad head gaskets. if it checks out and its a good deal then do it they are awesome trucks and run even better tuned but make sure you put a fass lift pump on it to extend the life of your injectors
Thanks alot for your reply! My biggest concern would be changing the injectors. The LB7 you have to take the top part of the motor off. Not being a diesel mechanic, I'm a little hesitant in doing so. I dont want to make a mistake because it can be costly. How was doing the injectors?
Lb7 would be my last pick lol my 04.5 lly has 195k miles on original everything. Injectors to. Try doing that with a lb7
I bought my 05 gmc for 7500.. no rust no dents new transmission, 228k miles on the truck. Got offended 20k for it a week after getting it... buts it's my dream truck
Also the lml cp4s like to go out an destroy everything else in the fuel system. They make cp3 conversion kits because of this
I just bought my L5P 2019 love the power and the smoothness. And didn’t break the bank ether.
$ 48,8995.00 dealer was amazing Bowmin Chevy MIAMI.
How did you get it for that price ? They start at $60k for a crew cab .
Quality Landscape and Hauling Co sedeno it’s South fla. I did the research. But if you like they still have I few of them. The only thing with the ones they have left there the LTZ models and I have the LT 5,000 difference.

This is the dealership
@@javiervaldes6953 Oh ok. Thanks for that. I'm looking to buy the cheapest diesel truck I can. The state of California is forcing me to sell my 2005 gmc duramax. Since it doesn't have all that d.p.f, d.e.f b.s. So I have 1 year left to replace it for a 2010 or newer diesel truck. Hate California government.
Quality Landscape and Hauling Co sedeno wow that’s bs 2005 is grandfathered in if it didn’t come with it, but if it did they can f with you. You could get good money outside of CA.
Great info and thanks for video. 06 LBZ left coast. Still rust free in 2020 😀
I have a bone stock 2006 Sierra 2500HD LBZ just under 300K. Doing manufacturer recommended or slightly better maintenance, running Rotella 15-40 the whole time, and replacing whatever minor things I have managed to only replace (outside of regular maintenance items): a water pump, two front wheel bearings, rear transfer case output seal, a couple of fuel line couplers, and a rear pinion seal. I would say these are dependable reliable trucks that will tow your RV all over the country if you take care of them.
You did a fantastic job! Great job “downgrading” to an older gen engine and I only say that because yeah technology gets better everyday but that also means the government can use that same tech to have more over reach into how we live our lives. You’re a believer so I know you know right where I’m going with that. On a lighter note, did you know that I was subbed to back road and watched your videos so much as well that I thought I was subbed to you but was not?!? I mean you’ve responded to me directly before lol. Anyways, fixed that real quick! Keep up the great work, God bless! 🙂
I have the 2006 LLY with "2" in the eighth digit place and a "6" in the 10th place. its a dually mint truck i picked up for 4 grand. love it
Here’s the ad from the guy I bought it from 2006 lbz duramax 2wd Have owned for 4 years and 66 thousand miles, been a great truck until the tourque converter went. No other major issues. Body is in beautiful condition for the year, truck has efi live kory Willis tunes on 5 position switch, 3in dp to 4 inch dual exhaust, turbo brake. 10k on new brakes all the way around, 2 year old batteries, leaf springs have just been gone through and repaired all. Has 5th wheel/ gooseneck rails with wiring plug in the bed and one down below, only rust on the truck is inside the bed up on the sides. Read Less
I went through the truck pretty well and it is almost pristene. It has very little surface rust on the bed wall. that'll get taken care of. touch the key and it fires right up. LOVE this truck!
In the garage with the truck running. Classic
Charles Campbell
And the garage closed😳
Wtf
Truck isn’t running dummies, the camera wouldn’t be that still and you’d hear the truck
I have a lifted 06 dually and I love it. Your videos have helped a lot with the mods I have.
Bought an 06 lly a month ago love it great reliable truck
Back to the LLY I check the Vin just to make sure and it was a match. So it's a 06 LLY 6 speed about 150000
