Well as much as I would love an easy fix I don't think thats going to be it. The truck sat for along time (about a year) so I drained the tank and put a fresh 5 gallon can in to fire her up. I don't think I over tightened the valve cover but I'll double check. I think my problem is way more involved than that. It probably has to do with boost and compression? I'll try the easy stuff first but I'm willing to put money on it that the easy solution won't work for me.
