Hi,

My car has had high oil consumption for sometime. Never really looked in to it too much was consuming 1litre 1800miles now 1 litre every 700-1000 miles. I was looking for another problem on my car and i came across this which i am thinking is a pcv/ccv valve. 

Seems like theres oil all over the top of the engine where the fuel injectors are think this could be the cause of my high oil consumption.

 

Anyone experienced similar also could somebody confirm this is a pcv/ccv valve if so whats the part number.

My car is a octavia vrs 2014 2.0tdi engine code: cupa.

Any help will be much appreciated thanks.

That does look like a pcv valve, but I don’t know for sure on your engine.
 

What I do know is I’ve just repaired a Vauxhall Astra that had high oil consumption and the fault turned out to be the pcv valve. It was drinking oil, and took only 200 miles to chug 1 litre of oil. On that car the pcv valve is built into the cam cover and I had to buy a complete new cam cover.

Try removing the dipstick whilst your engine is running and listen for a hissing sound, then replace the dipstick and try removing the oil filler cap, on the Astra it was not possible to remove the oil filler cap with the engine running as it was being sucked on by the vacuum through the failed pcv valve. The engine was basically sucking oil straight out of the top of the engine into the inlet manifold, and the owner had been told the engine needed replacing !

On your tdi with a vacuum pump, it may be a case of disconnecting the pipe on the engine side of that pcv valve and see how much it’s sucking, it should be less than on the vacuum pump side at idle.
 

Hiya. I have the same car with the same oil consumption issue. Are you any closer to solving the issue?
