Im having a brain fart right now, but i was wondering if the black box on the back of the block has a pcv valve on it. Mine does, and it runs a line to the intake manifold where there is ANOTHER pcv valve on it.

so are there suppose to be two pcv valves? one mounted on the black box and one mounted on the intake manifold?

no help? i know the thing in the black box is the pcv, is the one mounted on the intake just liek another check valve?

the block box is the crankcase breather box... on the box is the fitting but on the intank manifold is the pcv valve

Ldo

The L shaped thing is the PCV valve, all other straight connectors are just fittings for the hoses.

On GSR, the PCV valve is on the black breather box, on the LS/GS, the PCV is moved away from the box, but it's still an L shaped valve.

so there should just be a regular fitting on the black box correct? i have an itr head on a b18c gsr block.

yes, you should be able to just put the PCV directly on the breather box

there should only be 1 pcv right? if you guys have the pcv on the intake, what fitting do you guys use on the black box to connect the hose?
