Ok, I had a few questions on the evaporative emissions system.

First, the purge control valve (pcv) does not seem to have an electrical signal to it, it is "switched" via vacuum pressure from the manifold, correct?

Second, the check valve circled in green allows flows towards the TID, not away from it, right? (i cant see a situation that would allow otherwise, even without the check valve, but who knows.)

Third, will this modified setup work the same way, and more importantly, will it suck oil into the turbo from the crankcase as it seemed to be with no PCV? In theory not, because the PCV will close under boost, keeping oil out of that intake line, but I want to be sure.

Id prefer not to run a catch-can, because i'd like to avoid mounting more stuff in the engine bay, and it'd be one more thing i'd have to buy for this already expensive project.

 

I don't see why not.

I eliminated the charcoal canistor on my engine. I ran the PCV like stock and blocked off the bottom port. The whole setup is mainly to get rid of blow by contaminents that could otherwise contaminate the oil. Not all contaminents are removed though. Also its to keep the oil system from pressurizing if there was blow by.
