Catchcan plumbing question...

if i put a aftermarket pcv valve in the middle of this hose so pressure only travels to the rocker cover and not backwards to the plenum is this allright to do?

No, the boost pressure will escape into the cam cover. :headspin:

Hi Sk how are you going,thats what i thought was happening anyway.I thought the pressure when on boost let air travel into the top of the cam cover and let the blowby trickle into the cam cover at times of no boost judging from the previous threads.how does it work and so what you are basically saying is that it is best to block the pcv valve line in between the plenum and rocker cover at both ends

[Trust33]

Wait,so if i turn it arround and put it facing the plenum so the flow will be from the rocker cover to the plenum will it be ok.Or should i just go ahead and bung plug.?

the valve lets gasses move only from the rocker to the plenum. Just leave it there or block it off but dont try and turn the valve around. When in doubt, leave things as nissan intended

As Timd said, block it or leave it.
