Hello, my mini 2008 non turbo base model h, has 165,000 miles and has never given much problems.
I have an oil leak which seems to be coming from the bottom of the vacuum pump, i removed it and replaced the oring but it still leaks.Runs/drips down on the drived side of the engine dripping onto the exhaust pipe making an awful smell and mess.
Is there any way to rebuild these vacuum pumps?
Someone mentioned theres an oil pressure switch there that can leak too...not sure the location though.

Thanks for any ideas.

 

I know this is an old post but in case any one comes across this thread I have found this on Amazon, RKX Mini Cooper 1.6L N12, N14 vacuum pump reseal kit, it's an aftermarket kit that has the o rings needed to rebuild an vacuum pump. A bit pricey at $29.00 for 3 O-rings so I would recommend taking your old pump apart and checking for wear and with a new OEM supplier Pierburg pump at around $120 any sign of excess wear I would get a new one. the pump is easy to take apart. Mine had 170,000 miles and showed little to no wear although I was concerned with stories of pumps freezing up and snapping the cam off the timing gear. I can't see that happening unless their is low oil or pressure trouble.
