Thread: Crankcase Breather Options

So for those that have turboed n/a engines, what have you done between the rocker cover breather and the breather pipe just before the inlet manifold? Have you left the pipe running between them, or plugged both ends off?

I have connected a boost gauge to the inlet manifold outlet and for the rocker cover breather (1/2 in) I have connected it to the inlet between the turbo inlet and air filter outlet I.e preturbo

OK. My boost gauge comes straight of the Turbo actuator line. Think I may just plug them up?!?

Definitely don't just leave them connected or you will be pressurizing the crankcase. From memory I tee'd the rocker cover one into the large one from the side cover breather that goes to the provent. Inlet manifold one blanked.

Both open at the moment. Any issues just blanking them off?

Not sure what you want to blank off?

The T engine has a 19 mm breather on the tappet cover but no breather on the side of the crankcase. The na engine only has an 8 mm breather on the tappet cover. So if you have an na setup you need to vent both breathers to air or to a provent. I swapped to a turbo breather setup but to do that you need a turbo tappet cover which is completely different.

My provent vents from the side plate cover below the Turbo (n/a engine) then back to the intake after the air cleaner. The 8mm outlet on the rocker cover goes nowhere at the moment, can I just plug it up? Am sure I have seen others do this
