oil blowing out of OEM B.O.V
 
I have the factory blow off valve unhooked from the airbox, and first off it continuosly blows air when its jsut sitting there idleing, and i noticed some oil where the bov was pointing, so i wiped it off drove it for another day and looked agin and there was oil spay again.

what could be casueing this ?
why would it be blowing air constantly?

thanks in advance

You may have a bad B.O.V? Is it blowing air or sucking air from the B.O.V?
How many miles on the motor you may need to refresh it?!

Mine is / was doing it due to the Turbo blow bye. That usually means your turbo's are on their way out. I have a lot of shaft play and I can spray a mist in my engine bay. But I am going with a Precision PT76 Single Turbo in the spring after my car gets out of her winter hibernation.

turbos are on thier way out, the oil seals on the compressor side are kaput

Your BOV should be sucking in air at idle.

The BOV should be venting(aka blowing) air at idle if I'm not mistaken. If it is spraying oil, it is prob. due to your seals going bad on your turbo(like everyone said).
