Hard to say, at crusing a piston moved up and down 41 times a second.... do you feel lucky? lol just messing with you. A while i suppose, my 420a has a broken ring land in cyl 3 and has had it ever since i got it, I still beat the crap out of it with out any problems.

 

btw right out of haynes

for the 4g63
standard per cyl, 178psi
service limit, 139psi
difference between cyls, no more then 14psi

 

thats good I guess, I just want it to last the summer, I wouldn't mind doing a rebuild, but I just bought the car 2 months ago, paid $9000 and put another $1000 into it, and haven't gotten the chance to enjoy it yet

 

enjoy it now, have fun this summer because your wallet is going to hate you in 4 months.

 

wow so my numbers wernt off to bad, haha. Id say your fine. Dont worry im sure something else will go wrong before you need to worry about that. DSM's are good for that
