If you are running a lot of boost (15+#'s) a catch can system similar to SRZ's is really the best way to go.

I am running about 15#'s through my car and all I have is a decent set of breathers (one large one on each valve cover, and one smaller one on each valve cover), and it does the job just fine for me. Under extended periods of heavy boosting I may have to wipe a little oil from underneath my hood were the breather misted it, and then check my oil level, but for the most part this works very well for me.

SRZ, what unit do you have, and how much did it cost?

 

well, i am going to run a breather tank from summit.

It'll work same as a breather, except it catches oil too instead of misting it all over.
