Wondering if a Oil Catch Can is worth it?
How does it effect the cooling properties? Good possibility I will track the car in the future. |

The air filter provides no significant vacuum to the PCV system. It's there simply as a receptable for oil fumes, so that the fumes can get consumed by the engine.
The PCV valve is a check valve, to allow pressure out as needed but not allow anything back into the engine. It's not a bad thing to have, given that the other end of the hose goes to the non-filtered side of the air filter housing. The purpose of a catch can in racing is to keep oil and fumes from being dumped onto the track. The reason a (typically) 1 quart size is required is so that it's large enough to not overfill during a race. It is expected that the competitor will review it between sessions and empty as needed. You originally asked if a catch can is something useful, presumably for a street car. Generally, I suggest not. It's only real value is keeping the air filter from getting oily, which is not really a terrible thing given you'll be checking it occasionally anyway. And if you run an oiled filter like a K&N is really doesn't matter. |
