I had an issue with my 04 lly, poped the hood and there was a good amount of oil around the turbo area. Still creating the same amount of boost and still the same loud whistle it has always when I bough the tuck last August’s. The turbo is just about 2 years old. Some other issues were a...
So this started back about 6 months ago but my truck has been doing the rough idle thing when it reaches ~160 degrees. I had a mechanic shop tell me it's my lift pump but I don't think that's true because it was also doing this before I installed the lift pump. I had a buddy tell me it sounds...
