Hey Guys, i completely rebuilt my 88 LT500 engine. I did a leak down test. I started at 6psi and it dropped to 3psi after 6 minutes. Ive read that a 2 stroke engine will NOT hold air for ever, but its supposed to hold 6psi for 6 minutes. Well if it can do that with out dropping at all, then it should hold forever (technically). I guess im asking "what is a legitimate reading in this case". How much can it drop after 6 minutes and still be OK? 1 psi? 3 psi? I realize the less the better, but trying to be realistic. Also, i have checked everywhere (case halves, base of cylinder, PV, gaskets, spark plug, test equipment) and cannot find any leaks. I know its somewhere, but want to know if i need to keep looking or if its OK the way it is. I really dont want to pull the engine back apart. Thank you for the help guys!
