It's possible. I haven't had this motor apart from day one when I got it from H-Motors. I redid my tube coming off the catch can on the block, and I can blow through it pretty easily and feel air coming out the valve cover breather, so I think it's ok now. I'll find out today on my way to work...colder spark plugs and new can line...look out interstate.

 

i have been having the same problems with my setup as well too high of oil pressure so i have to vacuum pumps to hook up they are small so i dont kno whow much they will help but.. your pcv setup needs a source of vacuum. sounds like your bottom end is building too much crank pressure. im thinkin abiout runnin a pcv valve as well as a catch can stetup even though i dont like the hot oily fumes in my intake but. came that way from factory and it works and im hoping the catch can will relieve some of it when im in boost.

 

i donk know bro cant say anything must see it in person.

 

lets see pics of your setup.

 

You probably wouldn't know what you were looking at anyway. I know I'm building some crankcase pressure, although it can't be alot. It tends to start creeping up on highway cruising, and when I see it bumping up I just hit into boost for a few seconds and it blows on out and pressure drops to normal. I thought about sticking a one way valve on it (I've got this awesome valve from my old mini truckin' days ), but I really don't like the idea of sucking the oil vapor into my motor. I think it really just needs more exit points to keep the pressure down, so I'll probably end up pulling the 2 plugs out on the back of the block in the oil return galleys and putting 2 more ports in there.
Not sure if you're talkin to me, but here it is...

 

if you got rid of your pcv valve you need to add more spots for ventilation in your valve cover.
