Is an LB7 Worth it!?

[@nathansharp3999]

READ THIS IT WILL SAVE YOU $$$$$$. I bought an lb7 in 2003, I’ve still got it, I’ve learned a lot about it having owned one for over 20 years. The lb7 was designed by Isuzu, they designed the fuel system to use a 2ppm filter. Chevy decided to put a 6ppm filter on the truck, so basically the trash getting through to the injectors is 3x the size the injectors where designed to handle. If you use the stock filter set up your injectors will fail. There is an adapter available for $99 that allows you to use a 2 ppm cat filter. The filters are only $20 which is about 1/3 the cost of the standard filter. I’ve had 3 sets of injectors on a 320k engine. I installed the 2ppm filter with the latest set, done 200 k with no problems. I got a good deal on the improved injectors online at injectors direct.

[@eurowerx4267]

Hey there, who sells the adaptor?

[@ogr7771]

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.

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.

I returned the first one because the oil was full of diesel. W my experience now, I could have fixed that easily and that was a good deal. Instead I traded an 06 WRX with a friend for his 03 Silverado 2500hd. He told me head gaskets were bad I think and that it had injector issues. I later learned everything about it was trash. Interior was moldy. A shop installed injectors poorly which broke the heads and most everything where oil flows. Regardless, w no diesel experience, in 3 weeks I rebuilt the engine block up. Cleaned and painted parts as I went. Cast iron ppe heads which I ported. Ppe exhaust heads to down pipe which I also ported. ARP head studs. Sac 45 injectors, switchable tune. So $11g in parts above block including tune. So it drives pretty great. Since then I’ve bought a 52k lb excavator, a tracked bobcat skid steer and a motor home. Now managing and servicing 4 diesels and hauling huge loads w the truck as well as daily driving it. I average 16 mpg. Replacing entire fuel system on my bobcat now.

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.

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

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 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 .

[@CustomOffsetsTV]

Hell yeah

[@codyhall5370]

02 lb7 460k, race tune for the past 30k still runs like a top. Take care of them and they take care of you.

[@cmcd082]

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.

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.

[@joshuaflowers736]

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.

[@tracyshrable4224]

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.

[@bigblocklawyer]

What's going on with it that's a maintenance nightmare? You're doing something wrong.

[@thespeedymex]

My lb7 just hit 900k still getting 28 mpg in my multiple cross country trips. Seattle to Charleston South Carolina every summer. one cp3 since I got it past that it's a monster

[@bcdieselsofficial]

How do you get that mpg?

[@thespeedymex]

@@bcdieselsofficial well it has a tune and apparently I'm not special Im told it's an lb7 thing. Oh also not driving like the typical diesel truck owner and you should be good to go.

[@joeystubblefield3721]

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.

[@donaldthomas5852]

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 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.

[@mattcash7215]

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

[@TopNotchPropertyServiceLLC]

I love the sound of an lb7 so much so that it’s my dream truck regardless of any injector issues. The general verdict i’m hearing is that if you pickup an lb7, do the injectors right away and toss a lift pump on there to filter the fuel and they should last a long time.

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

My Lb7 has 378K miles on it. sitting on 22x14 chromes. Super sick trucks.

[@Loudyotaa]

The family truck was a 2003 LB7, my parents drove it to 260k on the original injectors, now my brother is driving it daily with 360k. The only major thing it has ever needed was the injectors. The engine and transmission have never once been torn into. All this while he still gets 23 mpg on the freeway with 22x14s and 35" tires. What more could you ask for??

[@eurowerx4267]

2002 Duramax, Just installed the 3rd set of injectors. I’m at 168k miles. Dealer warranted them in 2006 at 60k miles. Replacing them sucks!! And it’s expensive if you buy AC Delco. $6k in parts with fuel supply and return lines, gaskets etc 😅😅

376k, 2 sets of injectors. Only problem I've had is with power steering issues. I do my own maintenance. Replaced front wheel bearings, changed oil, fuel filter ect...no matter what, this truck will crank up and run no matter what injector issues I had. TOUGH AS NAILS. no transmission issues at all. It's worth attacking the injector problem head on and it'll be ready for use and abuse. Plus....the LB7 has a raw sound...there's a difference than the others
