Thnx for the reply. Currently I haven’t got cover off photo. Would this do for the time being?

For the purpose of the above mentioned oil issue, does the ccv or decanter system have a valve like the one in pcv system which could be taken out and cleaned/replaced?

Can't tell you anything else with the cover on.

The CCV is under this, circled in red, it is a spring with soft membrane. The electrical connector is a heater which stops condensation forming from oil / water vapours that come through from the CCV. The flow is in the direction arrow given.

I don't see an oil decanter system at this stage, but I do see some suggestive signs the CCV is most likely worn, you would need to check in the intake nearest the turbo for excessive oil, the oil if present will pool in the intercooler or lowest intake pipe. The wearing of the CCV is the spring may sag, and/or the membrane becomes hard and/or breaks/cracks.

Hope you find this useful.

Thank you, your reply covers a lot which i wanted to know.

I did check the intake between turbo and airbox. It contain signs of oil but not excessive. I haven’t check other the intercooler and lowest intake pipes.

If I open the cover of the ccv, as u said if the spring is saggy or the membrane is too hard then it needs replacement; right?

Btw, the excessive oil consumption could be due to the age of the DPF in my age. Milage is 260k km and recently I had it professionally cleaned but still it seems it needs to be replaced. Frequent regeneration of the dpf can dilute engine oil and it also cause too much consumption.
