[QUOTE="ramonpowerstroker, post: 939726, member: 11342"] Well after around 2 months of sitting the trucks valve covers came off to see what was up. I did a compression test on all cylinders and I came with above 350 for all pistons. This made me believe I had a fuel leak from an injector line or somewhere on the rail, and after running the truck without valve covers no leaks were seen. This only leaves the "ford" reman hpfp I put on it.. And if that's so this pump only lasted 8000 miles which is not that impressive. Truck have a aftermarket lift pump so I know there's no contamination especially when I'm a high mainance guy. The truck originally had a problem in the morning when I went to the bank and the truck made a slight shutter and the rail pressure dropped to 3.something k psi. It went to normal and I posted about it on this forum... Later on I noticed I was using slightly more fuel than usual but I paid no attention, this leading to a red light where a pos t/a wanted to race. Light turned green and I left with about a 1/2 to 3/4 pedal to 75mph. Turned into Walmart and saw oil everywhere.. Looked all under the truck and it's dripping "thin" oil.. I don't know why but This made me believe I cracked a piston of course so I drove the truck home where it was parked and I used my little mustang for my daily needs. So all in all I believe maybe a seal gave out on the hpfp causing a fuel leak that filled the crank case causing oil to be pushed out of the ccv hose.. What do ya think?:confused: [/QUOTE]
