ok im pressure testing my entire system but while doing this i was noticing a hissing sound.... of course it was a leak... i tracked it down and it turned out it was coming from my crankcase vent! what does this mean???? is it normal when pressure testing????

 

How much pressure are you pushing into the system and is your motor on TDC or overlap stroke?

 

overlap stroke?
uhhh and so far only about 7psi
