i love this **** though. its funny, all of my neighbors think im some kind of professional drunk mechanic.

the look on their face when i tell them that i'm into government auditing and the corporate side of an auto manufacturer is hilarious. all they see is my greasy drunk *** messing with a loud *** truck

oh, and that spark plug has been that way for atleas the last 1,000 miles lol. i figure since the first time i hit the nitrous with luke03's dad riding with me and the truck **** all over itself on the initial nitrous hit.

the plug was still firing somehow though because after about 3 or 4 backfires it came alive lol

99 stock bottom end. 140,000 HARD miles. just goes to show what a good tune and proper maintenance will do.

i still think the motor is hurt even though the leakdown cam out so awesome. it's just consuming so much oil and blowing the tube. the oil is 100% not a leak. my only guess is its being pulled through the intake and burnt off but im going through a full quart every 1k miles.

still running stock pcv system. at the same time, i have a buddy with a ls1 with a bigger cam, spinning more rpm on the same shot of nitrous and he has never pushed a dipstick out of place. but with my leak down results it makes me wander wth is going on. the motor passed with flying colors i was honestly hoping for a reason to rebuild with forged pistons i've got a sickness
