Default Pcv & fi?

Ok, so I did a leak down test on my piping the other day by disconnecting everything from the turbo outlet forward and pressurizing it to 20psi.

Immediately obvious were the leaks into the PCV system from the throttle body elbow that connects to the passenger head, and then the passenger intake port that connects to the valley cover (LS6 PCV update is done on this motor).

To fix this, should I simply connect the PCV port in the intake to the passenger head and block off the throttle body elbow and the intake port?

Other than that, there were only a few minor injector oring leaks which were resolved by simply rotating the injectors back and forth a few times to seat them better. No leaks @ 20psi!

Searching is good.

So what's the best check valve to use?

mine is very simple.

ls6 pcv -- check valve -- intake manifold

blocked off ports on valve covers

tapped -8 lines to each valve cover to a breather catch can

passenger tapped


big catch can with breather


no smoke from engine bay on dyno
