GMC PSmoking
I have a 2002, 2500HD with 185,000 miles. I have read several responses for the Duramax Smoke problem. I have the same problem. I have white smoke (only at Idle and low RPM), and it has a faint smell of diesel, I pulled my oil dipstick and found diesel in my oil. At first, I thought it was the injectors as well, I had the injectors tested and found the pressure was at 2 and it should be at 0 (at-lease I was told that), so the GMC dealer changed my fuel filter and flushed the line. While at the dealer, the smoke did stop, until I drove the truck 10 miles, then it started again. My truck runs good, and I have been pulling a lot of trailers over the years (big trailers). I have not lost any oil or coolant, and my truck has no signs of leaks anywhere under the hood, no cracks or signs of any head-leaks.
Can anyone help me out with this. I am tired of spending money and no-one fixing the problem. If the engine is shot, I will trade it in. I hear all kinds of opinions from valve job to blown head gasket. Any one with experience?
