Turbo Oil Catch Can

[Zmechanic]

Yeah I was going to just vent it to atmosphere but I figured since its a dd it would help by using the intake to create a vacuum to pull the air through. If the oil is actually being separated from the air then I don't see a problem by doing this since it will just be caught in the can. So far I haven't seen any blow by so I will assume its working. I will check next oil change.

Nice work on the catch can.

Just a curious question... But under higher boost conditions, wouldn't the manifold pressure be a decent amount above atmospheric pressure, while the crankcase should be near(ish) atmospheric pressure, causing air to flow out of the manifold and into the crankcase? Am I missing something, or is this kinda backwards from what you were hoping it would do?

the catch can is only hooked up to the crankcase breather and the valve cover breathers.
