as some of you guys know i've been dealing with a blow by. it had to take a back seat to my back surgery which i'm about to get ready to get the staples pulled. so soon i'll be back under the hood and trying to figure out why it's giving me this problem. I was asked what type of heads are on this car are they hydrolic or ?, reason i'm asking is because i was going to pull the valve cover off and see if i can see if that problem cylinder has a bent push rod and i was told this would be one way to eliminate what may not be the problem. So before i pull the head off and make sure i didn't crack the head or blow a head gasket i wanted to know if anyone can give me the info on what type of head is on this car? i'm pulling 120+ PSI on all cylinders with the exception of the front drivers side.
