So yesterday about 10:30 in the morning i go start up my truck. I let it idle for like 15 mins. Me and a friend jump in and i get about a hundred feet out and then i noticed it had NO oil pressure. At all! I pulled the dipstick and there was plenty of oil, AND water on it! WTF? So i pulled the oil cap just to make sure and yup! Water again. Dam, it still runs fine... Like noise wise and its definitely runnin on all 8. No smoke either. What do you guys think? I hope its in the heads. I want new ones anyway.

That'd be my guess. Compression test.

It ain't goin to run good for long with no oil pressure and your oil and water living in the same house. Compression then leak down.

+1 compression test. i'd drain that oil out and park it under something with fresh oil.
