@Doktor: can you explain a bit more?
#1: i only have one, shared, gasket ... are you saying turbo-air is leaking due to the extra turbo-pressure? and ...if the dynamic seals are shot in the turbo, then oily-air will be getting pushed through as 'bubbles'?
#2 I just can't visualize how/where the vapors are coming from to get in my turbo. My valve-cover vent current goes to my air filter and has it's own "catch can" there ... which drains back into the oil pan. I do not have the VCV vented to the turbo elbow.
on a semi-related note, i'm 1/10th of the way to cleaning up the engine. what a mess.
thanks all

My Looked like they were the type that are self locking and had one end pinched in slightly.
Since the Nut holds down both intake and Exhaust I think it would get too hot for Loctite to be useful.
When I took my Maniflods off I put a precision straight edge acrossed them and fournd that the Exhaust Maniflold was a little warped.
I can't remember if the same was true for the Intake.
I reused the old Manifold Gasket by putting on several coats of Copper Coat Gasket Cement/Sealer.
The Glue parg of the Copper Coat will burn off but the Copper Particles mixed in the Glue will squash and help seal things.
I have had no obvious leaks; however, I have not gone looking for any leaks.
