Nothing big, s480 over marks 72. I will let the builder post the pics since he fabbed it all by himself.
That is what my truck did, minces the losing the oil filler cap, because the hole in the piston was huge and it wasn't building any compression.Sounds like a piston
Did you have the infamous oil painting under the hood like I did? My truck did the same as you say when I put a hole in #2 piston
Well didn't go so well last night.... First run I went easy on the 150 tune then 2nd pass I turned it up and 3/4 track I here a loud pop from either the oil cap blowing off or the motor. Pulled over, oil everywhere from the cap beeping blown off, excessive blow by now, sounds like its missing on #6 cylinder (checked it with the scan tool will do compression test Monday) shaking bad, didn't see any smoke coming from exhaust though. Any guesses? Piston, rod, hopefully stuck injector? Lol.
