E90 Vacum Pump leaking oil help please

mat · 03-28-2012, 02:45 PM

Hello all,

I have identified that my E90 2006 318i SE saloons Vacuum Pump is leaking oil at the back of the engine.

I was going to leave it a while but the occassional burning drop of oil putting smoke into the cabin through the vents has now progressed to an occassional judder when setting off which leads me to think some of this oil is seeping into the clutch assembly (its contained right underneath) and contaminating the plate.

So, Im going to have a go at replacing the O ring on the Vacum Pump to see if this helps before replacing the part.

Has anyone ever removed the pump on an E90? Its just visible from underneath right up close against the bulk head of the car but not accessible from there. I assume you access it from the top after removing all the cabin filter assembly but talking to a BMW indy yesterday he said you have to remove the VCG to get at it!?

Surely not... any help would be greatly appreciated.

Hi all,

I actualy did the repair, replaced both oil seals and its now sorted.

There is no guide for the E90 and I did it without removing the rocker cover despite what BMW and two indys told me so it here if anyone is looking to do somthing similar.... hope it helps

Cheers

Mat

Job well done. I just received a quote from the BMW dealer here in Holland. New valve cover seal and vacuum pump seal for a 2007 328i (US specs): EUR870!
Prices determined by Head Quarters in Munich....
