w211 oil in the throttle body
I have w211 2005 e240 2.6 engine
The problem is that I found oil inside the throttle body while I was cleaning it
and I have some oil leak in the face of the engine ( front side ) but i already changed the cover seal recently
1 : any one know why there is oil inside the throttle body ?
2 : how can I found the leak place ?
another question :
this part in the middle , is it pcv valve or not ??
Thank you
