Who *hasn't* had Injector Problems

[mcmonroe]

Just so that we can have a perspective as to how wide spread this injection situation is:

1) Who hasn't had injector problems?
2) What year is your truck?
3) LB7 or LLY?
4) How many miles on your truck?

I really worry about an injector failing and spewing fuel into the crankcase. What are the various symptoms that a truck will have when it has injector probolems? Any things that can be done to reduce the odds of having these problems?

No problems on my 2003 LB7. Why worry about it? If you look at the numbers, most do not have injector problems. Do what you can (e.g. additive and extra filter system) and enjoy the truck. :D

[CopperStar]

No problems, so far. '03 LB7 70k miles, all balance rates <3.

[Idle_Chatter]

2001, 86,000 miles, no problems, balance rates all <2. smile.gif

[Rockin]

No problems yet. '04 LB7. 21000 miles. Haven't checked balance rates.

[glclary]

56,000 and no problems. Right now its still my all time favorite "ride".

I was kind of paranoid about it for a while being this is my first diesel and not knowing what to expect. Then I decided that if it ever leaves me on the side of the road, I'll just pour gas on it and set it on fire. :D

[Heartbeat Hauler]

2001 LB7 30,000 miles so far so good.... :D

I have a 2001 LB7 with the Allison. About 30k miles now. No engine problems at all.

The truck is all stock, and I replace the fuel filter every 10k or so, and don't use any fuel additives.

The only problem the truck has been in the shop for was a minor leak from the transmission gear select shaft area (near the NSBU switch). This was fixed under warranty.

[mark45678]

79000 mile on the 2001...no problems! 2004 lly 17K on it had a injector shorted! not a problem with the fuel end .. :eek:

[BassinRVer]

66000 miles and all is well on injectors.

[More Power]

Early 2001 LB7 w/38,000 miles. This truck has never visited the dealership for a problem.

Have not used a fuel treatment, and it is currently on its second fuel filter.

[Blacktruck-1]

2001 LB7. 58,000 miles. Juiced. No injector problems. Just an occasional lope at idle.

[upfront]

I have not had any problem, but only 8000 miles on my 2002 one ton.

[Buck]

No problems with my '01 LB7 with 62000 miles ;)

[DMAXED]

early 2001 24k no problems so far

[max out]

20589 miles on my juiced 03 , no problems so far.

[jbplock]

03 LB7 with 29kmiles - no injector problems to date.

I have two added filters (at 6kmi) and have used Stanadyne Blue with a dash of TCW3 2-cycle oil since new. Also no power mods.

2001 LB7 with Allison 18,000 miles K&N air intake and using Standyne Perf fuel additive. No problems.

[rickdlance]

2001 Chevrolet 135,000 miles then it needed injectors.
2001 GMC 105,000 miles then it needed injectors.
2004.5 35,000 miles and it needs 3. Waiting for them to come in.

[jim659]

Late model LB7, 5000miles I have **10/230 drag file with air and exhaust mods, also propane. I run the truck very hard and use a custom blend of additives no problem. I think adding a high quaility additive helps to lube the moter giving better lubricity to the injection pump.

[OC_DMAX]

I have a 2002 LB7 Duramax with about 20k miles. The truck is used only on weekends for family outings (pulling travel trailer and several boats). It sits in the garage during the weekday. The truck has never needed service for the injectors. All the balance rates are less than 1, with the exception of cylinder #1 which is -1.70. The truck have been running a Pre_OEM Racor 2 micron filter since around 12k miles.

I had the ECM/TCM updated with the latest software (Feb 2004) and the intermediate shaft lubricated for the steering rattle (and it is starting to rattle again). Thats about it.

I plan on trading the vehicle for a new one in the 2008 timeframe (usually trade every 5 years, but I will stretch it this time to 7 years). I really like the truck and would stretch it farther, but I do not want to be exposed to the possible $4K liability if the injectors do go bad (which looks like a fairly high probability after 100K miles).

[saywhat]

40,000 miles on my 2002 LB7 and no injector problems.Stock filter changed at 10,000 mile intervals.OC-DMAX injectors should be warranted up to 200,000 miles.

[FlyRod]

2004 LLY 2,600 miles, no problems at all! Completely stock

[Runaway]

43,000 miles + and no injector problems here. Use an additive when no in my home area.

[BMDMAX]

2002 LB7 with 50K + miles. 20K of them at 500+ HP levels.

Zero injector problems. FPPF fuel treatment every tank. (Fuel testing did show that my local diesel provider had very good/clean fuel right out of the pump)

Last 8K with Kennedy Mega filtration, fuel quality is now excellent. :D

[OC_DMAX]

Saywhat wrote:OC-DMAX injectors should be warranted up to 200,000 miles.

The only problem is the new warranty is limited to 7 years (7 years / 200K miles). So for those of us that put on low miles every year (7K miles in my case), the this new injector warranty really buys us an extra 2 years. Personally, I feel as if the warranty should be 200k miles period.

[Turbo Al]

I agree with OC-Demax, but am still not too worried about it. Mid 2001 no real problems of any kind, no fuel additives and on 3rd fuel filter -- Hey Jim get with the program and change that filter a little more often tongue.gif

[cowboywildbill]

2002 with 46,000 miles, no problems except: warranty replacement of a bad relay for the air conditioner when the truck was new( took 3 minutes for them to fix) and a blown fuse for the door locks. No repeat problems so far no injector issues. I change fuel filter every 6,500 miles. I did have a new filter that was dirty and had rust in the bottom of it right out of the box from the dealer. They said it wouldn't have hurt to put it on, I said no please give me my money back. I buy my fuel and oil filters from NAPA, and my trans filterss from allison. "Much cheaper"

[TraceF]

2003

64,000 miles

NO problems (I am knocking on wood)

I think the 2-mic pre filtering helps but I can't be sure. It don't hurt ;)

[Kirkes]

No problem here

70000 miles

[richp]

2001 K-2500 with 78k, about half of which is towing a 12k fiver. No problems yet, knock on wood.

2001 GMC LB7 100,000km no problems, on second fuel filter and soon to be changed

[lor]

No problems at 35,000 miles on a stock 2003 2500HD towing a 10,000lb fifth wheel full time.

[Rick T]

2001 LB7 with 47,000 miles. No problems whatsoever (waiting for my tailgate cables to fail). If all else is in good shape I'll keep the truck through a post-seven year injector replacement. Love the air ride suspension and I don't want to pay to put it on a new truck.

[crafty]

One of the first LB7 2001 6 speeds sold in Ontario (Dec. 2000), 45,800 miles (73,700 kms.) and no injector problems. Stock fuel filter, changed every year (21,000 kms.) and no additives. ALWAYS buy fuel from one of two places unless I'm away from home and then I only go to the major fuel truckstops.
Only one problem with the flywheel that was replaced in the summer of 2002 and a few other minor things. I had my last truck 15 years and I hope to keep this one that long as well. :D :D :D

[typecast]

'03 with 38000 miles, no injector issues. This truck runs great!

[D-MAX]

At 10,110mi GM found #1,5,7 fuel Injectors bad and replaced them, At 10,338mi GM found #3,2,4,6,8 Injectors bad and replaced them also I now have 39,450mi and AOK, I never had Injector trouble with my 2001 Duramax. smile.gif Traded in 01 for 02 with 28,000mi on it. smile.gif

[reel time fishing team]

2001 78,000 miles no injector problems but I have had to have the tranny replaced (66k) and it is back in the shop for something yet to be determined (see thread I posted today).

Kirk

[NETMINDER]

'03 LB7 70k never been back to the dealer 30,000 miles

[dmax515]

2001, 51,000 miles (no mods or additional filtering). No problems, getting around 17-18 unloaded, no smoke or fuel in the oil etc. I think it's a little louder now but no other symptoms yet.

[NFLDMAX]

2002, 60,000 miles, no problems yet

[Yamahauler]

My '03 Duramax "only" has 36,000 miles on it, but it is not my daily driver either. It sits in the garage all week long, and only comes out on weekends to tow a 12,000 lb toy hauler. So even though my truck only has 36,000 miles on the odometer, about 34,000 of those miles have been spent towing its maximum rated capacity.

NO problems what-so-ever with this truck.

[Dawg]

2002, 37,000 miles. No problems here.

[dakotakid]

2002 LB7 with 40,000 miles and no problems yet.

2004 LLY with 2,000 miles - still new!

Pat

[reel time fishing team]

Well an update to my previous answer. After replacing my tranny at 65k we are now replacing my injectors at 77k. Ridiculous. I wish you guys better luck than I have had. I had planned on keeping this truck for 200k miles but no way now. Time to start looking for a new brand.

Kirk

[d-maximus]

2002 LB7 36500 mi No problems at all,has not been back to dealer since I bought it new.

[Bigwheel]

Well, I have a 2002 LB7, with 20,000 miles, had one injector act up when truck had 1,500 miles, started using total power FPPF, and Cetane Boost, has deffinetly made a difference, other than that, it's been a awesome truck!! :cool:

[crashdnt]

2001 Chevy 2500 HD/Allison/LB7 28,000 miles.
Starting at 15000 I had an injector fail about every 2000 miles. Finally on the 5th injector and many long conversations with Chevy Customer Service, Reigonal managers,Dealer managers,Dealer service pesonal,and service techs., Chevy released the letter about the faulty injectors and have now changed all 8 at once. They claim it is the cure-all. I only have drive it 1200 miles since, and no problems as of yet. Good Luck! crashdnt@aol.com

[Riverholic]

[Travis Baker]

I have had injectors replaced three times. I don't know if it is a real problem with the injectors or a problem with the computer. I think GM should be ashamed though.

[J Dawson]

I have a 2001 with 99000 miles with no injector problems so far. The injector pump went out at 85000. I've had a 2 micron racor post oem since 73000 miles. Knock on wood

[Alan Lutz]

Early 2001 with 155K miles. Use Lucas fuel additive regularly. Have had Mega filter installed post OEM for 90K miles.

[KGS]

2002, LB7, 40k miles, not yet :rolleyes: Actually, haven't had a single engine related problem at all, couldn't say the same for the '95, 6.5TD I used to own :eek:

[Commuter Cop]

2003 LB7 25,000-no injector problems thus far but did have A/C, Serv 4WD problems and 3 instrument clusters

[MaxRock]
