    Default High Performance Sealed PCV system.

    I am slowly getting back to my 2.2 Turbo Fuego engine build, and am looking to design an effective low maintenance PCV system that effectively reduces oil vapour transfer through the turbo, inlet and intercooler.

    Some of the catch cans and separators are just empty cans and require manual draining.

    I was intending to use a helical refrigerant oil separator. They are designed to separate oil from refrigerant gas in a low velocity environment and return it to the compressor (the engine in my case).

    I will be running a crankcase vacuum pump and vacuum regulator to provide consistent vacuum (and flow) at the crankcase and will put the pump on the outlet side of the separator (as apparently the carbon pump seals don't like oil much) and vent it into the turbo intake pipe.


    The ball float on the separator activates a needle valve that allows scavenged oil to return to the sump when required.

    Anyone used a refrigerant oil separator (or seen one used) in a car?

    The separator I intend to use is similar to this one, but with 1/2 inch solder on fittings for inlet and outlet (should be able to just use a hose clamp for my purpose)

    Anyone got any tips for keeping crankcase blowback in check?

    I do have a venturi pipe mounted in the exhaust that I could dump the breather gases into but I need it legal for engineering/roadworthy and would rather it be the best system it can be....

    Have you looked at a Provent? (Mann+Hummel)

    Yeah. They look quite good, but they don't self drain (not the biggest issue in the world) and iirc require filter changes.

    It would be the easy option , but where's the fun in easy
