Ok I just swapped out my b18b1 out and it had a catch can with 2 hose on that connected to the back of the motor I believe for the coolant then the other hose goes to the front of the intake manifold.... So my b20z does not have the catch can hole so I just thought it doesn't need it so do I connect the nipple in the back of the motor to the top of the intake manifold with a direct hose or no what to do!? Need to finish this tomorrow thank you

 

Anyone?...

 

Not for coolant if it goes to the intake manifold.

There is a black box on the B20, right? The LS should have this, but it was deleted and replaced with the catch can I would guess. The parts on the LS should swap over to the B20 if you want to remove the black box.

Of course, I am assuming all of this. Next time, post pictures, too.

 

obd2 ls/b20 have the pcv valve in the valve cover. use an obd2 ls/b20 valve cover, pcv, and hose. route to IM.
