DIY: Dual Oil Catch Cans 370Z
 

Also check out Radium AOS. Pretty small size too and great quality product.

What are the two lines that go into the intake arms? I always thought those where what we would hook to the catch cans?

why does every car manufacturer do this when it is not good for your engine?

Easier and safer, you would be amazed by people ignoring regular oil changes let alone having to drain can of oil that can fill up and cause problems.

There could be other factors like complying with laws. For example, the EGR system used in some cars is not the greatest thing for engines but they had to do it for emissions.

what size piping diameter do we need for the crankcase?

Do you have a link or picture of the bracket you purchased at Home Depot where you connected to the catch can to the car next to the filters?

The bracket you want is dependent on the setup you're running. I just used some thin L-brackets I had lying around, cut to size, and drilled mounting holes on both ends.
