I have a power brake vacume pump leaking engine oil on front of engine, it looks to be the body of the pump leaking. ive looked for reseal kit and all i can find is block to pump oring. does anyone know of a reseal kit available for these. I know when i worked on vw they made a kit for there vacume pumps because the cover seals would leak, love to know if anyone has ever found a kit, thanks Eric. its a 2011 xf sc 5.0l

 

It's just a single O-ring and is very simple to replace. But you might check the bolts first. Several guys have found them lose.
There is a small chance it's the O-ring on the vacuum port to but that has only been reported once that I know of.

ok thanks for your response, i have that oring, do you know if i need to drain oil before removing pump? ps bolts were tight.

 

I have not changed that O-Ring only tightened the bolts. Others have said it will leak oil so they drained the crankcase before swapping the O-ring.

Would you happen to know the size or part number of that O Ring?
