Pcv chamber full of oil

[The Lion]

I've taken off the plenium chamber to replace the fuel pressure can in the rail and I noticed the pcv chamber full of oil is this normal? Ecotec l36

Oh the pcv was replaced 8 months ago

No, that doesn't seem right although a little oil isn't out of the norm, only under high vacuum conditions does it suck air via the PCV valve. Is the vent hose fitted between the bottom of the the throttle body going back to the intake manifold?

Pull the PCV valve out and give it a clean with some carb cleaner or similar and pull the little plastic bung out underneath and give that a good clean too.

Ok if I blow into the pcv it doesn't seal , sometimes if i push the check in an out it seals sometimes but mostly not ,,it rattles inside , and it sucks though the top

It should rattle, IIRC you should be able to blow through it in one direction but not the other.

Ok I'll replace it ....also the plenum chamber gasket kit there's 2 gaskets similar bit one has holes for valleys an the other nothing do I fit just the one or both ? Mine has the valleys

You have a vx?
If yes. The 2 gaskets on the far right for the plenum is the left one.

The right one is for a vt s1.

I have all the symptoms of a bad pcv not sealing properly ...but come to think of it I think it might have started with a bit of brake fade could a failing pcv in a vx ecotec affect braking?

Vx eco fuel pressure hose to the return?

No I don't think brake fade will cause a PCV problem. Poor vacuum might cause braking issues though, but more a lack of brake power.

Vx eco fuel pressure hose to the return?

The hose coming off the fuel pressure regulator is the return.
