ok cheers

keep them blocked, will do no harm

iv cut that s shaped pipe in half now and blocked both bits.. should i unblock them or is it ok to leave them blocked?

Dont worry about the smaller pipe, it passes through a hole no bigger than a pin on the rocker cover so you wont get any oil mist through that one, the engine breather is the one you have got going to the catch tank in your other post

dont think so as the reason the other one does is because the way it routes. It comes out of the rocker cover and goes down to behind the throttle body. Pretty sure you just leave the s shaped one where it is.

but the reson for having an oil catch tank is to stop the oil going into the inlet? so if you leave the small S shape pipe going from the rocker to the inlet, then oil is still going to pass from the rocker into the inlet aswel as going into the catch tank?

the small one as in about 5mm? that just stays on the rocker cover and the inlet. its the other thicker one that needs to go to the catch tank iirc

any one?

Yesterday i made a quick oil catch tank which a few of you said i done it correctly but the really small bendy pipe that goes from the rocker cover to the inlet manifold should be blocked up aswel am i right?

Because if thats not blocked up, then the oil that passes through the rocker cover and into the oil catch tank is also going to pass through that pipe and into the inlet?

x16xe engine btw
