Vacuum pump leaks oil

My vac pump is leaking oil from the bottom bolts. The dealer says that I need to change the whole pump? Is this true? It looks like I can take it apart and change the gasket. Anyone have any experience with this thing?

Hi ! I think there is a diy thread for this, maybe on the 5 series forum, I had a leak from the new pipe running down the back so looked like it could have been from the bolt, so replaced the clip and tightened, cured the issue. hope this helps a little !

There is an o-ring that can be replaced fairly easy. Other things to do in that area, would be to change the oil pressure switch. Both of these job should take no longer than an hour, & around 20 bucks at the most.

Here is the link for the repair.

I know about the o ring but mine is leaking mainly when the car is not running. I witnessed with a mirror that it seems to be coming from the bottom 2 bolts in between them? Could the o ring do this?

I recently followed the instructions from this thread. Same as above follow the directions and you will have no problem. Also the two hoses on front of the vacuum pump have one nut each holding them in place. remove the two nuts, be careful and move both hoses so you have access to the pump. On the pump you have three torx screws holding in place, two on top and one on the right hand bottom side. Please make sure you get a replacement vacuum pump gasket and a oil pressure switch both totaling $20 together. Change them all to prevent from doing it twice.

Make sure that you buy the gaskets from this site

http://www.bmpdesign.com/product-exe...arch_model/154

It will save you time. I replaced the o-ring on the timing cover (which is the only one that you can get from the dealership) only to find out that it was the outside cover leaking . I ended up having to buy these o-rings and do the job again. Do it right the first time especially while its all out.
