We just had 8 injectors replaced on the 01. Dealer found a lot of fuel in the oil. I was concerned about bearing or cylinder wash down and they said no worries. Now less than 1000 miles after repair and the first time towing since the repair it broke. Not sure what exactly yet, but it is siezed. Went from running great up a big hill, water temp 200 F, oil press 40-45 psig, egt 1200-1250 F, boost 18-23 psig. Then lost power, lots of noise, almost like exhaust sounding, and we barley made it off of the road. It died and would not restart. Opinions are appreciated. Do you think this could be caused by diesel contamination of the oil? Any chance of warranty or am I on my own? If I am on my own, where can I get a good deal on an engine for a 01? Thanks!!

Did the SES light come on?

Just seconds prior to the loss of power and failure.

If you have access to a code reader hook it up and scan for the codes.

Sounds like the hose popped off. Check your big blue turbo hoses both going in and out of the turbo and intercooler.

Did the injectors get installed under warranty? If so than this could be related and covered also.

then if you have a way of reading it, find out the code, predator, powerpup techll will do the job, it does sound funny that the motor siezed up from pulling just after an injector replacment, any idea how long the crankcase was full of diesel, maybe it has nothing to do with fuel, find the code

Mice in the pistons?? (Meltdown?)

I have no way of checking codes on the truck. All of the turbo hoses are still on. I did find my egt T-couple wire laying on the turbo housing and not routed where it was when I pt it there. I will have to test and see if it is damaged. I can understand how the mechanic could have moved it out of his way while doing the injectors and forgot to tyrap it back . The injector job was done under warranty. I tried the key this morning and the engine is still locked up, not that I really expected different. The oil is black. and rancid smelling, and has 1000 miles since change. The dealer changed it during the injector job because of contamination.

rancid, does that mean diesel smell, go figure it should not be black yet, any mods done, if you want pm me, i had a buddy that blew a piston from overheating, but truck still ran, and pulled to the next dealer on seven pistons, smoking like hell, but still ran and started, or it could be an injector failed and loaded a cylinder with diesel, which now it is hydrolocked, and cannot be turned, or i would say some big bottom end problem, to bad you could not find a scanner for the code, keep us informed, want to find the answer myself, diesel in oil is never great on bearings

Autozone and Advance auto parts both have scanners that you can use free of charge. I am not sure if they will let you take one home with you to use, but I do no why they wouldn't if you left a deposit on it and returned when you were done.

THe engine is warrantied for 5 years/100K miles. The years have not expired yet, but how are you on the miles?

This is just a stab in the dark, but are you positive they even changed the oil at all? Does the oil filter look new? Check your service invoice and make sure they put the right oil in if they did.. Kind of a basic thing, but people make some bonehead mistakes sometimes....

Speaking of bonehead things ~ just today a neighbor was telling of his 01 leaking fuel. Took to a Sacramento dealer to have it repaired. Fuel sensor gone bad ~ $800. Was told not covered on warranty. Paid the bill and by the time he got to the fwy, it overheated. Back to the dealer, forgot coolant. Oh well, replaced coolant and off to the fwy again ~ now its setting codes, lights coming on ~ whole bushel load of issues. He is an elderly rancher and his point was that dealers no longer have integrety. Customer service is an oxymoron here. He had a problem, took it to a serving dealer and rec'vd 15 problem back ~

My experience at the dealer was so so on the injector replace. The truck has 120 k miles so over on miles for engine. The mods done are down pipe back exhaust, AFE intake pipe and filter, edge with attitude monitor. The dealer I went to had no issues with the mods and actually liked the Edge for it protection ability. When they replaced the injectors, the first thing that happened was it over heated, it appeared to have an air bubble in the system and overheated then suddenly the temp came down and the low coolant light came on. I stopped and refilled the coolant tank and noticed fuel leaking on the rail feeding the injector under the fuel filter. I took it back and they fixed the leak. I also had them replace the fuel tank sending unit at a cost of almost $600. Truck seemed to be running fine around town and on 1 short hwy trip. This is the first time I have towed with it since the injector replace though. The warranty service record shows replace oil, but who knows if it really was done. I will call the Service Manager first thing Monday and hopefully he will be helpful. I will also try to seek out someone with a code reader to see what th ECM says. If only it was an LS1 I could do it myself!

Have it towed back to the dealer who installed the injectors. anything related to the repair is covered for 1 year. sounds like they did not replace all 8 injectors like they were supposed to - shame on them. It's an 01 so injectors and pump are good for 200,000 miles. If you can prove a lack of lubrication caused problem you should get a new motor. Good luck!!!!

Kinda late now but I don't think it was a good idea to leave your Juice hooked up. If the regional rep has to get involved and sees it......not good. Good luck and keep us informed.

i would remve the edge as well, with towing, it could be a concern sounds weird, need to find the code

The dealer finally got the engine out. It is siezed. They can't get the pan off because they can't get the torque convertor off to remove the flexplate and get to the back pan bolts. In draining the oil, they found a piece of brass screw and lots of metal. The rep had them remove the heads and found the tops of the pistons and heads look ok. This leads me to believe we are back to a lack of lubrication problem caused by the injector failure and 4 quzarts of diesel in the oil. My gut is badly spun main bearings and or broken crank shaft. Honestly I am wishing I would have just stuck with gas engines now, but a little late for that. The offer from GM is to pay 1/2 of the bill. New engine $7100, labor $1300, flexplate ? ($150), Torque convertor ? ($700), misc $500. That will leave my half at aroung $5000 for the generals poorly designed fuel injection system causing engine failure. Another note they found on the warranty history is that GM warranty was charged for 8 new injectors in Nov. 2004 before I bought the truck. I had them replaced in Jan 2005 again and the old injectors did not appear new. Just another great example of Stealership service departments ripping us and the General off. At least the service department I am dealing with changes the parts they charge for. Do you guys think I am getting the shaft? I kind of feel that way. Or should I be happy they are paying for part of the engine that I believe was caused by the injectors.:rant: :help:

Stick to your guns. I'll bet you can get GM to pay for the whole deal if you fight for it. GM admits they have injector problems by extending the warranty. You have your injectors changed after dumping fuel in the crank then within 1000 miles you seize it up? I would be putting up a good fight.

Someone here brought up a good argument a few days ago. If GM tells you that the diesel in the crank didn't do any harm tell them you are going to start filling the engine with diesel instead of oil. Diesel is cheaper then oil and if its OK to run it you might as well profit from it. Watch them try to weasel out of that one.

This sounds more and more like the repairing dealer didn't actualy change the oil when they did the warranty work.


As was said stick to your guns, if the injectors went bad and washed the lub out it's GM's fault, they pay. If the dealer didn't change the oil as stated, it's there fault they pay.

Fightem and fightem hard.

You damned right they're giving you the shaft!! You should not have to pay a single penny. Don't let them walk on you. Stick to your guns like eveyone here says. Reading these kinds of stories gets me really pissed.

Mine ran till 215k then 1 injector, 225k 2 injectors, around 230k all injectors,at 282 motor went kaboom!! 02, bone stock. I believe due to the fact that every time an injector went bad, it dumped fuel in the oil, the bearings finally gave up. Put a new engine in in Jan. & now have 137k on it . Total on the Ally is 418k. Already changed an injector at 127k on this engine. If it dumps fuel in oil, do not believe them when they say "it wont hurt anything". Ever use diesel to wash grease off your hands or take rust off of tools??!!! Dont believe it lubricates very well.

I pull a 5th wheel also, this is the reason I bought this truck. So far its been great, but these damn injectors have got me wondering. Its one thing to break down on the road in town, but out in the sticks with the family and kids with a big 5th wheel, would be the pits. Sounds like GM, should pick up the tab on this one, its kind of curious that this happened after you had your injectors replaced. Good Luck!

If you can show they billed GM for work that wasn't done, that's mail fraud plain and simple. Take the tech out for a good lunch and pick his head. Lots of times the techs are told not to do work that the company gets billed for.

I actually had a tech approach me with that situation and Frod Mo Co., it was the deciding factor in my buy back case.

Fight em all the way!
