That is the PCV valve / oil separator as used on a giulietta diesel as well.

I've not looked at one close up and I've not seen membranes for sale so I've always assumed you need to buy the complete unit. Maybe someone else has been able to open one up. You should be able to clean it out but if the membrane is torn then it won't be working properly possibly causing excess pressure and oil content into the inlet pipe just before the turbo.

 

Yes, turbo intake has oil, for this reason I want to change it.
Can PCV somehow afect the DPF filter?

 

I had same on my 2.4, after buying brand new one that hasn’t lasted long went for oil catch can which solved problem ( so so)

 

There will always be a small amount of oil in the turbo pipes... even when new....its just how they work. It will be the same with a new separator. Don't worry unless it's excessive.

 

Some oil vapour will condense in the intake, also the turbo will drip a bit.
So, the intake will be oily, always, worry when you see a puddle or blue smoke.

 

Hi Moises. Were you able to solve the problem?
Thanks

 

I don't know, I just changed but didn't check oil in the turbo intake.

 

Thanks for your reply, Moises. I'm thinking of changing it, but I'm afraid it won't work because the replacement is expensive. Could you please check it out? Thank you very much.

 

I'm sorry but i don't want to disamble anything. If someday I check It i'll post It here.

 

How did you change it as it looks like an awful job? The separator pipe to the sump looks to be trapped by starter motor. I've been meaning to change mine for about 2yrs now due to oil consumption, but more recently I've spotted quite a big oil leak from that area.

 

starter motor needs to be removed and there´s a hided terrible bolt but if I could you can do it too.

My car consumes 1 quart of oil every 700 km because of the oil separator.

 

The oil separator on the diesels return the oil to the crankcase and sits lower down, generally harder to spot leaks.

Or do you mean the oil was blowing through it into the intake.

 

How do you know it's the oil separator?

 

Every 700 to 1000 km I check the turbine hose and there is a puddle of oil in it.

 

.

 

I thought some oil in there was normal. I suppose at what point does normal become not normal?

 

If it weren't for the oil consumption, I would be fine.

 

Waiting to get my GTV MoT’d a diesel late model Range Rover destroyed itself. Noise, lots of noise, lots of smoke, no noise smoke dissipated. Consensus of opinion was oil seals in the turbo had allowed oil into the intake. It may be an idea to see why your engine has such a high oil consumption.
