Oil Catch Can? Options

[RolinkHaus]

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.

Quick correction: I got to re-thinking and just looked at my 2L D-Jet. The hose from the PCV actually goes to the filtered side of the air filtered housing. So it'll get a tad bit of vacuum since it exists between engine demand and the minimal restriction of the air filter element.

However, the logic does not change: it's not a significant amount of vacuum and it's not intended to be*. IMO, the only reason to use a catch can in a street car is to avoid getting oil/fumes in the air filter and intake manifold, and I don't see how the juice is worth the squeeze.

I personally don't think it's a problem or concern for a street car.

*This is a different concept than using a dry sump oiling system on a race car. In that case, the dry sump suction stages will actually create a strong vacuum within the crankcase itself, with the purpose of keeping down the windage/droplets friction and seating piston rings much better. But this is a level of vacuum and oil control that we'll never see on our street cars.
