940 turbo still exhibiting high crankcase pressure symptoms

My 1993 940 turbo is still showing signs of what I believe to be excessive crankcase pressure. I changed out the oil trap breather box, and the hoses and thought that is about all you can do with the 940 turbo to ensure that you won't have excessive crank pressure. It isn't blowing oil all over by any means, just a few nagging leaks. Could this all be normal?

Maybe I should replace the filler gasket(I can tell it is shot, as the cap spins on very easy compared to my 244 with a new oil filler gasket) maybe the small amount of oil on the oil trap is normal, and I know if they have many miles on them, all of the redblocks seem to have a drop of oil at the trans/motor junction.


But, I am still seeing hints that may not be the case. It is seeping a little out of the oil filler (I have a new gasket, but don't want to change it out until I get this sorted), the rear main has the usual very slight leak, a few drops at the auto trans screens, and I am seeing a little oil on the new oil trap box. I also have an oil leak under the exhaust manifold somewhere that I can't quite figure out yet. There is a sensor under there.

I have also had problems with this car using oil since I bought it at 28000 miles!! NEVER had a redblock use oil, even the 242 that I drove for 23 years didn't use any oil. It will smoke on start up once every two months or so. I think it is the turbo seals causing these symptoms? Any suggestions are appreciated.
