Vacuum in the crankcase? By large amounts, 12"? 18"? 40"? please specify.
Did you plug the hose that connects to the top of the TB?

I dont have a vacuum guage, but if i put my hand over the oil fill hole it sucks my palm enough so it makes a reasonably loud noise when i move it away, THANX

By plugged, I meant closed off. Did you re-connect it? or actually plug it?
Reason I ask is that hose is the other end of the PCV system. If no air is allowed to enter that side, then the valve side will continually suck down the crankcase...including the oil.
