The point was just to relieve the pressure.
I wouldn't think circulation would matter.

I've heard that some sort of constant circulation is needed to keep some moisture out and to get rid of the blow-by gases... prolonging the life of the oil.

Yes, what you are proposing does make a lot of sense.
It looks like you've got all the bases covered - condensation of vapor / moisture, drainage, and purge to combustion.
The clear lines are a plus - this is why some (Japan) racers like to use those clear lines: to inspect the crankcase puke.

Cool, thanks... I'll add this on the list of shit to do before the road trip. Give it a real test in short time.

I had my hose pop off my pipe prior to the turbo inlet, and there was a LOT of disgusting coffee / mud colored liquid that came out of there.
I'm too lazy to redo right now, and the stock turbo puked it's seal a while ago.
When I change the turbo out, I think I'll redo the system too.

I couldn't believe it either. At one point I was draining about a pt every other run out of the thing. Drove me insane. Then after not checking it for a few days I pop my hood to see oil all over the back of the divider right behind the drivers side headlight and on the front of the drivers shock tower.... I'm thinking oil lines popped somewhere but instead it was the puke tank overflowing (mounted on the drivers shock tower) and the BO valve spraying it all over the engine bay. :faceplam:

We also know how tight space becomes in the FC engine bay with big turbo systems and FMIC's!

I'm thinking about a pt off the center iron and ~2/3's of a pint off the oil filler. I took a SS turkey baster and cut it down, used the gasket between the oil filler and the center iron as a template, cut that out of SS and welded it together, a funnel to keep the oil from moving up the filler. This is why the capacity in for the filler will be less. There should be little to no oil traveling up that. I'm also hoping that what does creep up the center iron will be pulled back slightly as I want to have the vac being pulled from there, through the filler neck, through the SS wool packed ~2/3's pt tank, through some hose, through a clear filter, to the primary turbo. We'll see what happens. I guess I should try to log the vac seen by the TID. I've got that secondary boost MAP sensor that I only hook up on the dyno.... that could do it. If there's no vac present, or very little... I may have to think about a small vac tank somewhere....... Hoping it doesn't come to that though. That would REALLY overly complicate things....

Thanks Ted. i'll get some pics up in the fab section when I start creating.
