LS6 PCV with catch can setup
Hey guys, i'm looking for input on how to properly setup the catch can with the LS6 PCV valley cover.
I added the route, LS1 valve covers, LS6 valley cover, LS3 intake, and Holley EFI TB.
Thanks guys!
No tee where you have drawn one. That is just allowing dirty air from the valve cover and the valley cover to be pushed by blowby into the catch can with no manifold vacuum source and no fresh air back in. So you will end up getting dirty oily air into the airstream in front of the TB
The left hand side after the TB where you have typed "capped" is where the clean side of the catch can should connect to.
Also, if it's a manual car and you downshift to overrun the engine down hills n such you may consider putting a 3/8" check valve on the clean side to prevent any oil from making its way into the throttle body.
