Oil catch can for n52

kobeballer96 · 09-22-2014, 07:25 AM

Yes I know a lot of you will say the stock system will act like a oil catch can but i personally think it sucks. When taking the intake manifold off you can see oil inside there, I know others have experienced this too. Where can I T off or what hose can I tap into for a oil catch can to work properly on our n52?

Oil vapor in the intake tract is a direct result of PCV (Positive Crankcase Ventilation); it's worse in forced-induction engines, but is a required anti-pollution measure (as opposed to dumping it into the atmosphere). BMW engines have what is called an "oil separator" that should be adequate to separate the oil out of the vapor that is piped back into the intake stream, although it's more effective on engines like the N52 than the turbo engines. Unless you're seeing clouds of oil smoke in your exhaust or your plugs are fouling, I wouldn't worry about it.
