Weirdest thing ever when I crank the engine it spins real fast like no compression sometimes crank it 5-6 times then it all of a sudden gets compression an cranks as if the timing was advanced to far an starts up an runs great . I have verified 0 compression on all cylinders an ive also verified 160psi compression on all cylinders give or take 10 psi. WTF is up with it bad oil pressure relief , lifters bad ? I'm stumped !!!
Trying not to replace engine but if I can't fix thats my only option
