Catch Can Install on a S14 SR20 Ques. - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I've seen instances where the catch can is connected to the valve cover and the other port on the can connected to intake piping.

I've also seen one port on the valve cover and other has a filter on it.

Can someone explain the differences and pros and cons to each if any, or what is recommended

In reality, your supposed to connect it on the back port. The idea of a catch can is to catch the bad oil out of the crankcase thats mixing with fuel. But the problem with our SRs is that, the front port has a tendency to push oil out into the intake neck. That oil then gets into your turbo and pushed into your intercooler.
