hey guyss

So My PCV Breather on my rocker cover to the inlet manifold all those hoses are cracked.

1 -=----- So, can i loop the manifold, block the pcv outlet and just run the OEM catch can at the other end??

2 ---------- Do i run a aftermarket catch can from the breather out to can and then from can return to the inlet manifold?

3 -------- What other options do i have?

SR20-forum have a thread for turbocharged and NA engines (theory is the same though). The diagrams are not the only options but the most common and functional.


I have my own sort of setup and hope to put it through its paces this year so will post up when it's all sorted

Do what I have done.


1. ERG stuff all removed. Made a plate to cover the intake manifold slot.
2. K&N filter on right of cam cover.
3. Line from PCV valve going to a oil catch can, then back though a basic filter.

Never had an issue.
