could be . pull it and give it a shake. if it rattles it's good if not replace it. or there cheap enough replace it anyway. if that's not it it might be rings.

Excessive crankcase pressure causes your dipstick to "blow out"...If it's not the pcv valve then you might have excessive blowby, caused by bad rings...If you can do a compression test, test every cylinder 3 times each so we can get an average for each cylinder...post the numbers up here if you can, good luck.

It's either that or your pcv system reaches it's limits when you are hitting those high rpms, or if you downshift and/or get off the throttle at high rpm's without pushing the clutch in....I have the same problem, and I have been doing some extensive research on this...In my findings, I learned that there is a way to test the pressure of the pcv system. With this, you can figure out the volume of air that needs to escape, which you can then figure out the size of all the hoses needed for proper ventilation of the crankcase....

with boost breather caps should be fine...
sounds like your set up should be pretty effcient.... you still blowing out your dip stick?
no i dont i have tapped both valve covers and have a i think its 1/2'' that goes from passenger valve cover behind motor to other valve cover where i put a t then to a home made catch can until i get one from summit.i have a evaquation kit but im scared on a street car that it would cause a smoke film out exaust.i have checked compression all good motor only has around 300 miles on a rebuild only shows up under boost i was told the block distorts under boost causing blow by under boost.but mad this thing runs strong and idles like a champ all day long if i want it 2 and very responsive all this on fact tune comp but easy on timing 9% with btm on 1 and fuel pressure at 55 what else would i get from tune other than increase in hp ,is it to help strettability.i want a tuner waiting to get a tweecer rt after i re-group from santa
ya im going to use it myself to tune thats the whole about it that i like i have also heard how complex it is to learn i have talked to some people on this site who will share there information on sc tune files but im really surprised how good it runs and idles with stock comp.
