IF my concern is valid, than the catch can must be mounted at the same elevation, or lower than, the lower port of whatever cooler you use.

And that's another part of the equation, there are only a few spots to mount the catch cans. I wouldn't want to remove the cans every time I need to drain. I don't want to block access to things like the oil filter. And the cans need to be mounted kinda high so that they drain into the separate collection tanks(the capacity of the cans is very small). It's all a compromise.

 

Mines mounted high to avoid that gravity draining problem, it let's the oil go back into the valve cover, the condensation does get sucked into the catch can!
Again to clarify, I'm speaking of my 2.2 litre. It's also because of space constrictions.

 

Yep, no chance for blockage on yours!

 

So take one and put it on a tilt. Inlet is high, outlet is low. Your piping looks like it could collect a lot. Many bends and long runners.

 

I see curves from the valve cover to the inlet on the canister , then a curve from the canister outlet to the fitting at the throttle body inlet. Not much of a place to collect oil but inside the canister, most slides back down into the valve cover.

 

I guess I missed other pictures of the design.

 

Did you mean to quote me, Cat Man? It's probably hard to tell from pics, but at it's worst, it's level. Oil residue may get left in the tubing, but it shouldn't be enough to clog.

Again, love the idea of a cooler, I'll have to look at more of them to possibly find one that wouldn't cause low spots. Or else I'd have to relocate my catch cans lower, and I don't think I can.

What I'm looking at is a lot of tubing to (collect or cool) the oil vapors. Remember a bend being 90 or 180 equals more in a straight line due to restriction of the bend/flow. A cooler could do that in a lot less space.
Where is your oil separator mounted now? I know you built the PCV cans up front awhile ago and mounted air sep canisters near the radiator.
Granted the engine compartment on these cars could be a little more user friendly.

 

Here is the turbo-side can



The one on the left is where the new, larger catch can for the intake side is mounted. It's mounted pretty high, which is limiting what I can do here.



I'm looking at this cooler, straight line and about 3/8" OD. A little pricey. Might work for the intake side, if it can pass around the hood latch.

It's a little tight but that might work
