Should there be a negative pressure at the hose to the turbo when disconnected from the oil separator or is it neutral and allowing of any excess pressure from the crankcase. Would we need a few revs to show this condition up? Would gummed up exhaust baffles cause a back pressure thereby preventing scavenging of the crankcase? I'm planning to test the pressure with and without the muffler connected. Any comments welcomed.

Yes
