I got my catch can....so when I install it do I keep my PCV valve? Do I need breathers?

 

Which one did you get? I just installed the Z06 valley cover but I'm going with a catch can as well.

 

I got the one from Thunder Racing.

 

My catch can splices right into the system, before the valve, it bolts the passangerside head

 

Yes, you still keep the pcv valve, it's a one-way check valve, which you don't want to eliminate. The basic diagram of the catch can is:

Hose from valve cover/valley -> catch can -> intake

pcv valve can go before or after the catch can.

 

hope this helps
