Thanks for the reply. I got my truck back last night after being at the dealer service center for 3 days. I was really happy driving it home on the freeway. It seems to have all it's power back that was definitely lacking and is running really smooth. It was running really rough. I started it up this afternoon on my lunch hour and the damn check engine light came back on. I am taking it back after work today so they can check it out....again. It is so frustrating! Anyways, I did check with Triple A and they assured me that they did make a special stop to purchase the diesel that they poured in the tank. I do need to find a new diesel mechanic. My truck only has 50K miles and it feels like it's got about 250K. I live in Lomita, CA and take it to the Long Beach/Signal Hill area. Does anyone happen to know of a good mechanic in the area that honors the GMPP extended warranty? Thanks for letting me vent.

White smoke after idleing for a couple minutes.

I have an '04 Sierra 3500 Crew Cab with the 6.6 Duramax and Alison trans. I have experienced a new problem with white smoke coming frmo the exhaust after the truck idles for a few minutes. When it is running sitting still and then drive off, the smoke pours out of the exhaust leaving a smoke trail behind me. The other morning when I hooked up our fifth-wheel RV, the truck was making clouds of white smoke out of the exhaust. I have checked both the oil level and antifreeze levels and both are okay. Ant help/advice would be appreciated.

Did they tell you what the trouble code was for the check engine light? Did your truck on rev to 2000 RPM? had very little power? Jeff

Kinda sounds like a head gasket... You may want to keep an eye on the coolant level.. My 2005 just cracked a piston and blew allot of white smoke. It happened all at once though..
Good luck,

Duramax Turbo Leaking Oil
by glenn14

05 Sierra Duramax with 56k miles has started leaking oil from the turbo intake.
It drips down on the inside fender well just below the air filter case. The dealer
is ordering new turbo rubber adapter hose and clamps indicating that there is a crack in the hose. They did check for gasket leakage and blow-by at the manifold. I don't understand how oil is getting into this turbo intake hose that should only be getting air for the turbo from up by the radiator/front grill. What am I missing and any suggestions?

My 04 GMC Sierra Duramax Diesel has also had several sets of injectors replaced. I also have a recurring problem with the alternator system. The most recent event started with the voltage guage jumping around while running at high speeds and the lights were flickering. I had the alternator replaced 6-months prior to this. When I brought it in, they said weren't sure, but replaced the alternator under a part warranty claim. They also replaced a battery at this time. Coincidentally, two weeks later, the injectors failed. Is there any chance these are related in any way? It's been two months since then and now the voltage guage is starting to drop down to 10V when the lights are turned on. This is the fourth set of injectors, and at least the 3rd alternator.

Check your ground strap. Have you had a lift kit installed?
