I am a newbie as I stumbled across this forum, searching for answers to my twin Chrysler 440s.

I think I am experiencing blow by on one of my engines. Heads were done and compression is good on all but 1 cylinder which is 20lbs off. Anyway, I can't keep a dry valve cover gasket, PCV was new, but when pulled from valve cover, oil is around it. Breather cap on opposing side has oil around it and my flame arrestor gets oily.

Is there snake oil or a fix to keep oil from escaping through gaskets or to lessen the crankcase pressure?

Thanks!

I suspect a deeper issue is going on with your engines block. Sometimes the higher compression after a valve job does cause oil burn problems.
do these engines have alot of hours of use?, or years of not being used then put back into service? Sometimes it take years for an engine to die off
maybe venting the crackcase will buy you some time. It sounds like you are approaching a major on that engine. There is no magic available for this.

Can you pull the PCV out of the equation and substitute some other form of free flowing elbow so there are no restrictions, thus relieving the pressure?
