N/A 3sge & Oil Catch Can

Whilst I understand that catch cans are more beneficial for a forced induction motor, I've got a belief that a car with a high enough compression such as 11:1 would benefit from an oil catch can to ensure oil isn't getting into that compact air/fuel mixture.

In saying that, considering the 3rd Gen 3sge runs at 10.3:1, would it be beneficial to be running an oil catch can or does this engine have a reliable way of ridding itself of the oil from factory?

    The gen 2 3sge does have an extensive internal baffle inside the cam cover for venting to the intake. 
    Not sure about the gen 3.

    I suppose the best way to tell if I need one would be to inspect the intake manifold and see if there's any oil buildup. Now I just need to actually bother doing it haha

    Two reasons I could see a street car benefit from it.
    Firstly Is the oil vapor causing issues with detonation?
    secondly, is it causing a build up in the intake manifold/ports/backs of valves.

    If it is, fit a large catch can, low down with long hoses.  You need to allow the oil vapor to cool and condense in the can.
    Small cans are waste of time.

    after you've done that, you need to clean the intake. 3bond engine conditioner does an ok job but it can't fix years of build up.
    most workshops these days have intake cleaners that do a good job as it's very common problem with anything that has EGR.

    I bought some CRC throttle body/intake manifold cleaner, it probably won't do an insanely good job but budget lyfe. I'll inspect the intake manifold and if there's a lot of build up, I think that'll be a sign for introducing a catch can to the system
