You could have something internal causing your problem, bad seats or something else, I am using a aftermarket fuel filter that filters @ the 2 micron level, when my injectors were replaced at 157k, they were full of crud, dirty fuel = crud.My 2004 Chevy Silverado 2500 Duramax Diesel currently has 87,000 miles, I have had to replace the injectors 3 times, the last set lasted only 5600 miles. No one can explain or give me a rational answer as to why, have had it suggested fuel in CA is bad for this engine? Filter has been changed regularly & the truck is extremely well maintained! Any input on why this keeps happening??? PLEASE PLEASE, ANY INPUT WOULD BE GREATLY APPRECIATED!!!
you do have injector issues if you find fuel in the crankcase, poor idle, smoking at idle, and for everyones info injectors are covered up to7 yeras & 200k miles for 01-03 LB7's. Another policy supports the same thing but if they even think or see evidence of a tuner no warranty and they will black flag the VINhas anyone else had a problem where you have a really rough idle. i know diesels can be rough, but this is like massage chair vibrating. it goes away once i have it in gear. could this be an injector problem? i havent noticed extra diesel in my crank case. any suggestions wlecome
Don't blame the truck for this. Blame the mechanic that did something wrong.Two days after getting it back went to start it and it would start and run about ten seconds and then shutdown, like someone had turned the fuel off. Raised the hood and pumped the filter till it wouldn't pump anymore and it started. If the trucks sits for three hours it has to be pumped before it will continue to run. Back to GM, they don't have a clue what is wrong this time, some kind of leak in the fuel system. Still didn't have 100,000 miles on engine.
Very Very unhappy with My Chevrolet Duramax that was supposed to be built "Like A Rock"
