In today's video Dustin sits down to talk about the ever-popular (but injector issue having) LB7 Duramax. This Duramax literally set the stage for the whole round-eye/cat-eye lineage, and is truly an outstanding engine, considering how quickly it was developed. With that being said make sure you stay till the end because it's a good one!

I bought mine new in 2002, changed out the injectors my self in 2012 and added a lift pump and it has never ever let me down, stranded or been towed. I get over 20 MPG freeway and 17 around town. No plans of selling her, looks better than the trucks from the last 15 years too.
The 1st & best generation....
I got a 2001 lb7 only 93,000 miles. Runs great.
What size tires did you have while getting that mpg?

How many abour job. Picked up an 02 for a work truck and fell in love with with it. It has 400000km and will be laid up for a time and was thinking of doing the injectors. Thinking it might be worth it. It is a comfortable truck. I'm currently away in a beautiful Acura and it doesn't touch that old girl for just a just right comfy couch.
Ran an LB7 to 450k miles replaced 3 sets of injectors including original warrantied ones. Two transmissions, a complete front end job at 300k. Overall a decent truck, definitely not a truck for somebody who doesn’t change their own oil.
I have been working on a lb7 that was ran by an old man who took insanely good care of it. The truck has 430k miles on the clock and has is still original everything, only had 2 sets of injectors, and I am going to put its third set of injectors in this weekend and run it. Still original tranny too. On top of that it’s a California emmisions model, so it is really impressive
How’d you tear up an Allison 1000
Love my lb7, just hit 330 and still going strong. Don’t get me wrong, I’ve dropped plenty on it. But I love it. It’s got the Edlebrock heads and alleviates the need for injector cups.
@@A-Mistake-21 did the heads warp?
04 GMC LB7..208,000 original everything miles....injectors..trans...water pump...valves covers never been off
I love my LB7 it's never done my dirty or anything. They are the most unique sounding Duramax and just about everyone who has gotten rid of one regrets letting it go which is exactly why I'll die with mine in my possession.
Right there with ya bud love my old girl, got an 03
Same here brother
I got a 2001 lb7 93,000 miles it will never be sold. It gets 23 mpg highway 16 mpg local & city.
Got a 01 280k still running. I'll take it to my grave
Went through 2 trucks to get mine back bro Ik exactly what you mean but never getting rid of it again
I have owned 3 LB7 Trucks and they were incredible, other than injectors they were perfect with normal maintenance. I would add a lift pump if I had one today so the CP3 would last forever.
I bought one new in 2002 and love it has 270,000 on it. Replaced the water pump, fuel system, battery's, brakes and several sets of tires and that about it.
I LOVE my LB7. It’s got 374,000 kilometres on it. The Allison transmission is working perfectly. I’d rather buy it injectors than get a newer truck that is very pricy and has DPF, EGR, and DEF. And a LB7 sounds amazing with no muffler.
I love my lb7, the first set of injectors lasted 230,000 miles, I put new injectors and lift pump about 35,000 miles ago and has zero problem now.
I love my LB7, i've owned 2 LMM's and my LB7 drives like no other. Throttle response is great and its a nice smooth running powerful truck!
Just bought an LB7 with 40k miles. Throttle response is amazing. First diesel
@@shyguy2481 WHERE ON EARTH DID YOU FIND A 40k mile LB7???
@@ConnorRydland the Show Me State
Can confirm, 22+mpg fill ups are common in my lb7
@Austn sounds good. Got an 02 like new with 40k miles for 30k. Craigslist is advertising for 45 to 50k similar years and miles
I have a 2002 2500 hd lb7 duramax just rolled over 243000 miles. It's super clean for the age and has been a great truck for towing my travel trailer and horses. It's been reliable for me
After decades of running them I will always own a Lb7! Ya definitely get more efficient at working on them the longer ya have em. Have 3 running at moment. Still have the first one I ever bought. All stock 2001 service truck. 2nd I built a frame off 2002 date night/ road trip truck, and the 3rd is a 2001 "give it hell" 4x4 dually farm pig. As long as I can find parts I plan to keep building these things!! I love em!!
As a diesel mechanic i always get a good laugh at any ford guy who talks about how lb7 injectors are hard to change when every powerstroke up to the 6.4 had theirs under the valve cover while the 7.3s were easier to replace but 6.0s and 6.4s were equally time consuming if not more because ford loves to put the HVAC box directly over top of the passenger side valve cover and there happens to be an issue with that when it comes to getting the injectors out same deal with the 6.4
Love my 2001 LB7..never owned one before but getting to work on it like replacing the cp3 pump, water pump and fuel filter head to changing the oil..still learning more about it is awesome..wouldn't change it for nothing......loved you video..thanks
Love my lb7 165,000 miles and still on stock injectors. She's a towing monster!! I will keep this truck till they put me in a box.
Same.
You only got a little left
I have an LB7 with 190k miles and I haven’t had a problem with the injectors, but I’ve had to rebuild the front end, other than that it is an amazing truck
I have a 2004 LB7 and I have 102,000 miles and I had my injectors replaced under warranty. 5 speed Allison transmission is awesome. I plan to run a banks tuner and maybe a 64mm turbo. Honestly a great rig, don’t ever plan on getting rid of it
Love my LB7. 230,000 miles. stock turbo truck came in at 505 HP 1020 lb torque at 4500 ft elevation on the dyno.
What did you do to get 500 with a stock turbo
@@night_train_lb7 EFI Live, 3” intake horn, S&B CAI, PPE 3” downpipe, 5” diamond eye exhaust, Race common rail pressure plug (PPE), Fass lift pump, And a built trans.
@@stump3514 which trans did you go with
@@night_train_lb7 I bought a Duramaxtuner 750 built trans….it didn’t make it to 30,000 miles. NEVER buy a transmission from them, I would avoid that company entirely. Currently in the process of getting a 1000 HP trans from Inglewood transmissions built by Evan. They offer a lifetime warranty and have one of the best names in the business, that’s who I would recommend. Also, avoid dmitri at Nozonediesel, he has a terrible attitude lol.
Love my new to me LB7, yes I had to do injectors. But it made it to 350 000 miles on the OE set. Yes, the original injectors from when it came off the line.
Mine has 263,000 miles on the original injectors. I change the fuel filter every 10,000 miles and run Hotshot’s EDT and Diesel Extreme in it. I can’t help but feeling like I’m driving a ticking time bomb as far as the fuel injectors go though. I’ve got to get rid of this thing.
Bought my first diesel in feb 2020 and it was a 03 lb7 230k. Came with a bigger turbo. Was told injectors were done.. well couple months later. Started to haze. Ended up going with %45 injectors also did head gaskets and a few other things. Making 650hp. 1200lbft.. Absolutely love the truck.
Built trans?
How much did doing that much work all at once cost you, if you dont mind me asking?
@@lewisgeer1994 it was 3k for the injectors and Bosch lines. With hg and i did arp studs. In the end I was about 5k into it. Also had the heads machine's but that costed me $100.
Stock trans?
@@AndyGarcia-ch1ci it was when i bought it. limped trans a bunch. 5th gear was toast. i got a kit from no zone and did a billet build. built my self.
I have had my LB7 for over 5 years I am the second owner...I put a fass, 4" cold air intake 3" downpipe to a 4" exhaust 5" tip efi tunes...water pump failed i was pulling a 10K trailer to BC popped the hood to allow maximum air flow and kept her around 80-90 she drove another 170K pullin over in between and adding all the spare antifreeze i had plus all my water in the trailer but she got me settled until tow truck showed up the next day...she went down but not out...solid trucks!
Hey that’s my truck on the thumbnail!! Awesome
Picked one up a few months back with 90,000 miles. Its a single cab but i plan on keeping it as long as possible. Dont know what abuse its been through but im hoping no failures anytime soon
458k LB7 owner. driven daily and absolutely love it.
Iv had mine for 15 years and it's here to stay I believe ! Still pretty simple to work on for the most part compared to the engine space they give you on newer diesel engines
LB7 great truck. 480,000 on my fathers and only one set of injectors. Owned it new since 03 and has been a wonderful super reliable truck. No complaints
Bought my LB7 (GMC 2500HD short bed extra cab 4x4) new and have kept it in tip top shape. Replaced the injectors at 175,000 along with water pump. Transfer case replaced at 185,000. Truck has well north of 200K now and is bone stock with only a low level tune. Had is repainted last year and leather seats recovered. more than half of its miles have been heavy towing and I would not trade it for a brand new one. Day to day on the farm it pulls a DC 32' FMAX 210 or a 16' GN dump trailer. Playtime it drags a 42' Sundowner TH all over the country. I have only ran Rotella 15-40 dino oil and never added any additives to the fuel. All my fuel comes from truck stops and is pre-filtered through my transfer tank before going in the truck tank. I change fuel filter on truck every 25K or so.
I have an lb7 and I love it it was my late grandpas truck that I was able to by off my dad after he inherited it and I had to put injectors in it and have a PPE duramax tuner on it and it makes enough power now to be fun and reliable for as many trailers I haul in the lawn and landscape industry! 100% would recommend
21mpg with a bully dog tuner, and running 35×12.5×20 Patigoia mudgrips. Love my truck!
2022 and own a 2002 gmc duramax. I can’t complain, great truck!
Family had a Duramax for 14 years, Great truck! We did 2 sets of injectors on it and ran to 300,000miles, then we sold it to the next guy.
Though we have moved on, and I eventually bought my own cars as I became of age, I can’t mistake the distinguishable 6.6 sound for anything else. At the end of the day, in spite of our new fleet of Toyotas, I believe the Duramax to be one of the best and memorable vehicles of my time, I sure do miss it. Hopefully some day I can reconnect with the truck and it’s good nature that’s not though a TH-cam video.
Enjoy the things you have in life while you have them.
I owe one with 292k miles , the injectors were replaced at 100k miles on warranty and since then , I have never had any issues with it , great looking truck as well
Buying one tomorrow. Hope it doesn't have abnormal blow-by, or injector issues. Buying from a used car dealer friend. Excited to get my first diesel. 02 GMC 2500HD crew cab long bed duramax LB7, 260k miles.
GM and Isuzu first partnered in 1971on the LUV pickup truck and then the Spectrum car. Later, GM would own 49% of Isuzu stock virtually allowing then to run the company, ultimately resulting in the Dmax. Not sure any more, but at one time, Isuzu was the largest diesel engine manufacturer in the world . Whatever the case, they killed it with the Duramax series.
I love my 2001 Chevrolet 2500HD LB7. 605,000 miles and counting. Great truck. I've replaced some injectors and one injector pump, but transmission is original and with regular maintenance they are very reliable.
what is 'regular maintenance' on these trucks?
@@midnightclub7629 Oil/filter every 7,500 miles, fuel filter and front grease fittings every 15,000 miles, trans fluid/filter (drain & refill never flush) every 40-50,000 miles, serpentine belt, pulleys, thermostats and coolant every 100-120,000 miles. Things like air filter, brakes, shocks, ball joints, u-joints need to checked periodically and replaced proactively when they are close to worn out. I also put fuel additive in every tank because LB7s were not designed for ULSD. Hope this helps.
@@Nascarstud thank you
got my first diesel in 2011, 2001 chevy 3500 dually. i have never seen the 22mpg, but have gotten a good average of 18 going from utah to pennsylvania crusing along i 80. picked the truck up at 150K and have since gone through all the "reqd maintenance" 150K injectors, lift pump (3+ filter/primer failures), transfer case pump rub, cp3 failure, u joints, cv shafts and a weird turbo noise pulling empty and light throttle (sometimes, havent figured out) still i wouldnt give up this truck. this lb7 may struggle a little with what i'm pulling, but if i keep it at 60-65 it dosent really complain. sure i would like the power of a new duramax, paying almost 100K to replace what i got (for 13K) is just not a reasonable option. for me the lb7 just gets it done reasonably well, i'll keep fixin her up, we will see who goes first.
Drove by the Ford dealership in the fall of 2014 on a Sunday and saw a 2003, Silverado 3500 dually. Went home and got online and checked it out. Monday I was at the dealership for a test drive. While out on the drive it turned over 34,000 miles. Went back and said I'd buy it. Turns out, the original owner just used it to pull his 5th wheel camper and when not camping both were in a shed. Math shows he only drove it 3000 miles a year, give or take. Interior was immaculate and not a speck of dirt on the underside of the truck. At 42,000 miles it started making smoke. My diesel mechanic said injectors were going to be needing replaced soon. Got that done and I'm at 133,000 miles now and no problems. Probably going to put an Air Dog lift pump on it this fall to help things out. Love the truck.
How much did it cost to replace the Injectors?
Ames in the fuel every fill up & air dog.. i have a Fass & put Ames in the tank…prevented maintenance
Keep running hotshot in your fuel as well every now and again, keeps the injectors and fuel system lubricated and healthy
I’ve had my 2004 lb7 for 16 years… replaced injectors and pump at @ 320k miles…. Now I have 504k miles on my bone stock truck pulling a dump trailer for the last 10 years, I will keep this truck pass 1 million miles💪🏽💪🏽💪🏽
Excellent video man! I'll never get rid of "Pig the Alaskan Overland Rig" Pig's a 2001 LB7 Duramax | GMC Sierra 3500 Crew Cab Long Bed Dually with a freshly rebuild 1982 Perris Valley camper on the back.

Thanks again for the content 🍻
I have an LB7 currently as my DD. Such an awesome truck. If you let them breathe a little and throw a lift pump at it it’s a very reliable truck.
Absolutely, they all need to breathe a bit more!
100%
Owned my LB7 for a year now, favorite truck I’ve owned so far. Requires extra TLC but it’s an 18 year old diesel, what do you expect
Had an LB7 and absolutely loved it. Built top end and transmission… dyno tuned and it was the most reliable fun truck to drive. I crashed it sadly and it was wrecked.
atleast you are here to talk about gotta be careful man
I got an 04 with 320k. Second motor. Built trans lift pump 64 mil turbo bigger injectors and a tune. Absolutely love it. Smokes almost everything else on the road.
I have a 03 3500 with the LB7 and a ZF-650 6 speed manual transmission. It’s my favorite truck that I have ever owned. I got with 103k miles on it. It currently has a few electrical issues like passenger power lock window and mirror don’t work and the trailer wire harness isn’t working. It’s currently in the shop getting fuel pressure issues sorted. But I love it. Plan on keeping it until it gets wrecked or they stop making parts for it
Love my lb7 don’t plan on ever getting rid of it, lucky find w 74k miles
My lb7 was my first diesel, singlecab 03 cateye with a built trans. Miss that truck
I was looking at a 2015 duramax but then I saw a 03 and now I’m thinking of just saving my money and going for the 03 duramax .
Hell yeah
I had one for a while sold it and see it every day on the high way. Really regret getting rid of it.
I have 2002 gmc lb7 dually and 300000 miles and get 18 mpg love it
owned one at 16 years old with 480,000 bought for 4500 hundred bucks, got the guy down from 6,000 ran and drove great. only got rid off becasue i wanted a crew cab
I love my 2004 GMC LB7 mostly because it has no EGR or DPF/DEF. It sounds amazing with no muffler. Gonna keep her for as long as I can.
290k on my 01 currently in shop getting head gaskets and studs. Had injectors done at 265k. Truck is a beast I love it
Getting an lb7 today. This video as well as the comments have me a bit excited as been its my first deisel truck.
I love my LB7. Will never, ever, ever, own anything else. Just hit 300k. Was hit by a drunk driver, rebuilding the front end, then tho replace the injectors, factory, stock injectors mind you. Been Marvel mystery oiling her for the last 40k. Replaced the cp3 at around 240k, water pump around the same time. This is absolutely the best diesel I've ever used. My dad's lb7 had close to 1.3 million miles, 90% of that was towing horses back and forth across the country. I'm not sure all that was done with it, but it's still going strong. Best diesel ever. .
Love my lb7 362,000 miles and still going. best thing about the lb7 no emission.
got my engine out right now doing a full top end rebuild plan on giving it to my kid when she turns 16 it was my first truck and it'll be hers too
Hell yeah!
My buddy sold his for a 7.3 idk why I honestly like this truck better then a 7.3 and I’m a huge ford guy.
I have an 02 and it’s got 207k on it and that thing is a beast it has handled everything I’ve needed it for and I tow a cattle trailer with it.
02 lb7 460k, race tune for the past 30k still runs like a top. Take care of them and they take care of you.
As I literally just rebuilt my LB7 for my GMC 3500 Dually. 😂 dropped a valve and still ran long enough for me to scrounge its parts for a damn near complete rebuild and replacement of everything old and work. New Turbo, thankfully was able to save and rebuilt heads, new injector pump, new injectors, injector lines and every pump, seal, filter and bearing in its internals and a new cylinder 8 piston . All done in my literal home garage.
Take care of the Duramax and itll take care of you.
302,000 miles and now rolling again.
Mind you this is my first vehicle. I just graduated high school and this Dually kind of fell into my lap and i just fell in love with the machine. I just couldn’t let it rot
As of now just hit 302,545 she’s finally broke in. Turbo definitely made a difference, the heads must’ve been in really bad shape because now the truck idles smoother, faster and slightly louder. For a Dually is really hops off its ass and down the road much more peppy!
My 04 lb7 is at 423000 miles and still going strong!
I love my 01 pre emission it’s a beast 193k rolling good all stock for now
My Lb7 has 378K miles on it. sitting on 22x14 chromes. Super sick trucks.
I just picked up a 2002 GMC 3500 Dually. I grew up with my dad having diesel trucks. Started with his old 7.3 and then he got a 2002 Silverado with the LB7 and i WANTED THAT TRUCK. He bought it brand new, and he is just about to do his second set of injectors at 250,000 miles. the first set of injectors went out around 65,000 miles. The truck I bought needs injectors, thats the reason I bought the truck so cheap compared to what dealerships are selling them for. Its been hard to find one for less than $20,000 at a dealership, I got my dually for $7,000 because the previous owner didnt know how to do the work and couldnt afford a shop to do it. I bought the truck to run my Landscaping business, and I dont even notice the trailer behind me… I have a feeling this truck is going to be in my stable for YEARS to come, I love this damn thing.
Own one, absolutely love it. Now a little over 200k miles and still going strong. Had an injector fail last week so time for that pain that will keep it going another 100k+ miles... Will install an airdog at the same time to try make the injector last longer
One thing I love about the lb7 duramax is how affordable they are compared to the lbz, I do prefer the lbz but they usually have price tag of 25k. Are lb7 used to get 28mpg on highway after we changed the engine, witch had the recalled bosh injectors on it. Great video by the way I've just learned something new. 🙂
Is that hand calculated? If so, how do you get that?
Are you wondering about the mpg? if so then one big thing was doing wheel bearings. We gained 2mpg per wheel, we also had a aftermarket exhaust. Traveling at 120km (74mph) seemed to be the sweet spot, it was were the truck got peak mileage. Plus it had the recalled injectors on it. I remember before with the old injectors and the shitty wheel bearings we were getting 16mpg.
@@Andrew-ff4hh I see. No tune? What exhaust did you run?
@@bcdieselsofficial it was a mbrp 5" S60200AL oh and also we did calipers cause they were sticking
@@Andrew-ff4hh very nice!
I got an 2002 LB7 for $4k from a military guy needing to sell asap. It has 211k miles. I had to do the injectors right away. I had mine rebuilt for $650. Job is a pain in the ass. Ive put another $8k into with Hsp air kit and coolant kit. Also kryptonite front suspension. Overall I couldnt go buy a truck on the market like this for $12k. so i am happy.
I have both lb7 and lly and I’ll keep the lb7 forever probably
Had been wanting a Duramax since they first came out but had to wait a long while to be in my price range. Picked up my LB7 about 2.5 years ago with 221k on it. One owner/grandpa truck and I love it. Did the preventative maintenance on it (lift pump, rebuilt front end parts,etc) and it's been extremely reliable, had a water in fuel light come on and off a few weeks ago but traced the wire down and it was grounding out, of course that was after replacing all the fuel filters, WIF sensor/connector. Don't see myself getting rid of it anytime soon.
I have an 03 LB7 and I love it. 330k miles on its 3rd set of injectors. It’s bone stock and going to stay that way.
Im looking at an 01 gmc with the lb7 the injectors have been re done except for one an it has had a new cp3 pump put on
I got an 05 lly, I tuned it last year with efi live had some fun than blew a head gasket. I did the gaskets and studs so I’ve been there with lb7 guys. But shit you want to play your gonna pay. Dustin I’m jealous of your lbz🤙

I just bought a 2004 duramax LB7 silverado 3500 dually crew cab. Unfortunately, I just learned of some of the downfalls. Fortunately, the truck has been well taken care of and at this time rums, and looks fantastic. I am fixing to order a transfer fix kit to address the possible rub issue. And I'm looking to order a 165 Air Dog lift pump to hopefully give me some time before I have to replace costly injectors. But even when I do I will still will walk away with one badass truck that I'm proud of and will be for another 20 years.
I have the same truck 04 Chevy 3500 but with the 8.1 gas engine 5 speed Allison, it’s very thirsty for fuel 10 mpg highway 9 around town and home. Heavy loads 22,000 lbs 6 mpg. Got a 2001 Chevy 2500HD Excab 4x4 Duramax LB7 93,000 miles 23 mpg highway 15-16 city. I love my 8.1 but sometimes wished it had the Duramax for the fuel mileage.
I’m looking at that same truck right now was yours worth it so far?
Everyone only talks about the Chevy trucks and ignores for the most that the gmc trucks look pretty damn good themselves
Just got me a 2002 lb7 sierra just trying to figure out an exhaust debating on if I should tune it
Well hopefully I have good luck with my recent purchase. I just picked a 03 lb7 with 280k on it. Injectors were just done at 240k. So any tips for what might be coming up?
Got an 02 LB7, just had to do injectors! I can attest, worst job ever but, no repairs have been fun. But I love the truck
Ok so i have a 02 8.1 and i want to do a LB7 swap do i have to replace the Is wiring harnessed?
Love my LB7 Duramax! I use it as my tow pig for my fifth wheel. It’s always dependable even though it’s a maintenance nightmare. I don’t think I’ll ever part with it.
What's going on with it that's a maintenance nightmare? You're doing something wrong.

I found and bought the Holy Grail of LB7's. A bone stock, one owner 2004 GMC Sierra 2500HD 4x4 crew cab long bed with 186k miles. Did I mention the ZF6 that it has? Ive since installed an Airdog 150, up pipes, down pipe, 4in MSRP straight pipe, volant cold air intake, HSP traction bars, as well as fixed a few things that it needed. I recently ordered 45% over sac injectors that are on the way and a 64mm turbo. Eventually I'll replace the driver side exhaust manifold as well. This truck is awesome. LB7 for life.

Owned mine for 5 years and just over 175k miles. It's an 04 regular cab 4x4 built in the last month of production. Had it for sale but decided that would be a terrible decision
Would the LB7 be a good engine for my 55 chevy pick up ?
I bought my 2002 lb7 inb 2018 it had 198k. Miles on it. It has a air dog lift pump a edge tuner and air intake a big exhaust like most everyone has but i went one step further. I did a loud ass stereo in it that will make you wanna get out of it and i still have all my seats and nothing is seen. My next few plans for the truck are kinda extremely unique and experience so those might take a lil bit to get done. Love my lb7 oh yeah and before the unqiue stuff definitely a fresh set of 150 over injects and a bigger air dog pump

@@bcdieselsofficial efilive from Diesel power products. Whatever their fuel efficiency tune is
@@thespeedymex I will take that into consideration.
My first and only diesel truck I own is a 2004 lb7 duramax Silverado HD I traded my 2015 Durango straight across. Knowing that the truck had blown head gasket. There’s a few things u don’t mention like for one injectors are not like spark plugs u don’t change them once a year two the fact that the fuel runs in side the motor warming the fuel more so than it would be if it were out in the open easy to n cooled, actually allows for better burn the hotter the fuel is the better it will ignite less fuel waste potential for better fuel mileage as well
And yes injectors r a pain but it really boils down to quantity over quality
I’d rather go for quality
For the water pump i see merchant auto doesn’t sell a “welded” pump anymore. Is there an explanation for that? I thought the welded was better than not welded from what i heard. Should i just get a non welded merchant auto one?
Bro no way he did this video from my comment, I didn’t think he would have done this video that fast. That meant something to me 😂
Have a 02 lb7 has 320,000 replaced injectors once at 140,000 and that's it. Most of the miles are towing miles and still tows strong. Regular service along with air intake, turbo, and tune that's it!
I'm a ford guy, but I've never understood the complaints about injector placement on LB7's. All diesel engines at the time had injectors in the valve cover I.E. 5.9/7.3/6.0/6.4/LB7.
I'm picking up a 2001 GMC Sierra 3500 tomorrow, with only 86000 miles on it. It's 100% stock. What is the first upgrade I should do to it?
A lift pump works wonders for the injectors
Selling mine after 9 years😢. Been such a good truck. Damn northern salt
Love my 02 lb7 only ever replaced the injectors once at 260k now has 330k still rolls and tows like a champ
I am about to buy a 02 lb7 bro has 65k miles on it owned by a old fella and looks really clean . What do you think I should look for or should I not have to worry about nothing just yet since it only has 65k miles on it ?
@@dennismendez1626 wow what a find!! i’m about to buy one with 380k lol
The one way to fix the injector issue is a lift pump. Air in the fuel cavitates inside the injectors is what causes the cracking. A lift pump removes air from the fuel. Had a lift pump on the same injectors in my wife’s lb7 for 9 years now. Not a hiccup since
Ran my lb7 to 450k till I traded it. Would have saved myself the headaches I got on injectors if I just installed sac45s off the rip. Still loved that truck
I have a 02 gmc sierra 3500 slt dually love that thing
Question: Only pump #2 diesel on the LB7??
love my LB7 got 164k on the dash brand new injectors and head studs just put on
