I hope the good folks at Briskoda can help me get this straight, once and for all. Cos getting my head around the PCV valve/breather hose/inlet manifold set-up is driving me nuts. So much conflicting info and diagrams (not on this forum so much) has made me realise the OCC route makes sense.

I've got an oil leak and have been trying to sort it out. Rocker cover gasket change= still got a leak. The two mechanics I know are being really evasive (i.e; too ****in complicated for them). So I'm currently replacing a the breather hoses. I was intending to just replace the sections one by one, to avoid mistakes, but a lot of my system has been bodged badly, and some pipes just go to fresh air!Anyways I've got as far as the 'T' and, as we all know,this area tends to disintegrate and is difficult to access. I don't really know what the clump of pipes under the dipstick plate are; I'm currently trying to get the plate out! I have found the end of the breather pipe that goes in above the dipstick / oil filter area (into the manifold) is just falling out. But I've also found there's another valve in the pipe at that point.

That makes three valves! One on the 'T', one near the air filter (hockey puck) and now this one. Something strange here. No wonder my oil filler cap blows rather than sucks.

Does anyone know how to fit the rigid plastic bend piece that should be in this oil filter hole?

Are three valves found normally? Most info I've read suggests two. And I haven't even got to the 'other' branch of the 'T' section.

There's two great threads on briskoda covering this- but they're old and if I were to ask there, I'll probably get no answer since they're 2013 or something. And they don't cover the issues I'm bumbling my way through, like removing the dipstick plate, orientation of the two 'green' valves, and why my oil filler blows (Negative crankcase ventilation, if you like).

I intend to keep my VRS for at least another year and a daft oil leak is not gonna beat me.This is probably the reason the boost is poor, economy of fuel is down and the leak itself.

Thanks people

sorry mine is an AUQ 1.8T engine
