You all must be aware by now that I have this crazy car which has been a source of both pleasure and pain. I have some more pain but maybe not. So lets see what all of your opinions are on this. Here it is:
My Garrett T3/T4 seems to be smoking alot more now than when it first started (900 miles on the entire car now). I assume that the rear carbon seal in the turbine housing may be leaking and my PCV system may be contributing to that. Yes I have the proper Motorcraft PCV for my application and it is good. Compression test shows around 175 PSI all cylinders with about 5 PSI. Leakdown is about 20% (sure hope my rings seat soon !) Runs like a sonofabitch too! I fear that maybe I have equalized the atmospheric pressure and no longer have a positive ventilation through the cam cover. I drew up a small diagram so you may see what I mean.
I am just wandering if I add the check valve in the area indicated would this help? Also I have the system plumbed the way I do, so that under boost I can still pull any blowby through the intake instead of blowing oil out of evey orifice in this engine.
Thoughts, comments, all is welcomed. Dont knock my artwork either :)
This is how I have mine. My rings are shot. Without running the PCV and catch can and all, I was blowing oil everywhere, blowing blue smoke out the tailpipe, and everything.
Yeah, I had it the way you show but it didnt help. Its pretty much the factory setup you show you have.
Did you run the check valve too?
I have no PCV valve in mine.
Here is a pic from before I swapped the engine.

The block breather runs directly to the catch can as does the v/c breather. The port in the intake is plugged.
I run a small vac line to the turbo inlet to put a little vac on the can at all times.
No oil blowing or smoke (after I burned off the in the exhaust from the cracked head). Also no chance of oil in the intake.
Thanks Chuck, I think that is what I am going to try. I like your setup.
As it turns out though my problem with the smoke out of the exhaust was a bad carbon seal in the turbine housing. I have that getting fixed, so hopefully I will have no more problem with that.
