Oil inside throttle body?

Hi Guys,

I have a 320i M52 2.0. Today I noticed some small amount of oil inside the throttle body.
I have checked the CCV and there are no hoses going to the throttle body from the CCV, so how is oil suppose to get in there???

Also to the left of the throttle body there are 2 hoses and one under the body going from the purge valve, so I dont understand how oil can come inside the throttle body?

thanks,

rgds,

Mario

The hose from the cylinder head goes to an oil separator. From the separator there's a hose to your intake manifold and a drain hose back into the oil pan at the dip stick location. If your oil separator isn't functioning correctly you'll pull oil up into the intake.

I've had the ICV removed from the manifold, including the MAF and filter, and still I could't see that hose leading to the intake manifold, is it really neccesary to remove the throttle body to get the separator out including the hoses?
On realoem I can only see 2 hoses at the diagram for the CCV

I apologize for not being completely clear. There are 3 connections to the oil separator. The hose from the cylinder head, the hose to the dip stick and the grommet where the oil separator connects to the intake.

Here's a photo that shows where the separator connects to the intake. This is on a 5 series but it's still an M52 engine. Also here's a link to the DIY the photo came from.

Thanks for the reply. But can you tell me the 2 hoses right under the manifold where it states to replace them both with standard vaccum, where do they start from and what do they connect to?
