Oil Leak from Crankcase Breather Hose

[Alexander van Gerbig]

    I have noticed ever since the boost has been on that there is a some oil
leaking around the crank breather hose port on the block.  I sniffed around
the web and noticed on SJM's site that the 20v has a special valve the
restricts how much vacuum goes through to the crankcase breather hose.  When
the boost is on it sucks the oily fumey mess up into the breather hose, my
engine never came with any restrictor valve of any kind.  Could the new
boost be sucking oil up and out?  Bad connection at the breather port, leaky
hose?  Something worse?

    I have yet to check the airflow plate to see if there is any oily mess
there.  When I did the conversion I had to do a tiny bit of cleaning, there
was a tiny bit of carbon crud and oily yuck on the plate and surrounding
area, not much at all though.

TIA!
