Hello, I got one of those catch can / overflow tanks and I routed the vent on the valve cover to the catch can and I left the pcv hose routed to the intake manifold. Should I route the pcv line to the catch can as well? Thank you!

 

Catch can. The pcv line will overflow the most oil out of those two lines. Remove the pcv valve first too.

 

The correct way to do it is too actually leave the PCV in place, and just add an AOS in between the PCV and the intake manifold. Radium makes a really nice kit.

 

The vent is not the ideal location for the catch can, the PCV is where you want it on a single can setup.
