I'm doing a LS1 swap into my 3rd gen and I must have lost the PCV system or not had it on the donor car. Can I just fab one up with a universal PCV and some 3/8" tubing or just run breathers on each valve cover or just one valve cover or what? If so, any recommendation for a breather that works on our valve covers???



Thanks!

Combination of restricted PCV and breathers should be good, let's see... breathers to allow pressure to escape should that build up ..and slow restricted pull through PCV to keep the oil clean... a catch can in series to keep oil out of the intake. I went to fabbed breathers for a while but added a modified PCV in order to keep the oil in better shape

Anyone else have any ideas? Should I just put a stock PCV setup back on it?

I just ran generic emissions hose, teed it, bought a Ls1 pvc valve and inverted it. No need to go OEM.
