The BOV takes its boost/vacuum sources from the intake manifold and turbo after the compressor. Even if the BOV is blown or leaking, it wouldn't get into the crankcase, it would leak into the intake manifold and go out the throttle body or straight to atmosphere.

I didn't think about it until it was said, but this is a very good point. Maybe even go as far as blocking off the turbo outlet and do another test to verify it even more.
You mentioned that your timing tensioner went bad, was it the hydrolic part or the pulley. Does your timing belt get lose after sitting awhile? This Would mean the tensioner pulley isn't adjusted properly.
