PCV system schematic for AQF 4.2
 

Hi all, as above. Has anyone got a schematic of the PCV system please.

Many thanks in advance.

I dont know how much this will help. Here are the ElsaWin procedures/diagrams of oil retention valves and crankcase breather hoses.
Annoyingly, there is no picture how these hoses connect to the PCV and the intake manifold removal procedure is missing.

Thank you very much for that. I dismantled my PCV valve yesterday and it seemed abnormally wet with oil (and the diaphragm worn) which leads me to believe it's allowing too much suction through the engine and causing oil consumption. I'd like to rule the PCV system out before I embark on the process of diagnosing valve stem seals.

When I took the PCV valve apart on my old D2, there was no oil inside it at all. it was heavily coked up with carbon deposits but no oil.

Interesting. What kind of driving did you do? Mostly long journeys, short with stop/start or a mix of both? Ours does a lot of short runs so maybe that has something to do with it. Possibly excess condensation in the oil. . .

Mixture of both, I live just over 1 mile from work so general pattern would be 3-4 weeks of maybe 20 miles a week but then once or twice a month I'd do a 400 mile round trip to visit family.

Thanks for the info. I'm going to replace the valve as the diaphragm was in pretty poor condition. Oil was actually dripping down the tube that enters the inlet manifold from the bottom of the valve. Can't be normal. I'll post my findings after a few hundred miles. Hopefully there'll be a noticeable difference.
