Td5 vacuum pump leaking oil

[petmic]

I finally found the source (hopefully the last one) of the engine oil leak.

I got an oil leak from the vacuum pump. After cleaning the alternator, the vacuum pump and the engine block i let the engine to idle for 10 mins with the viscous fan removed. I discovered a drop of oil on the front of the vacuum pump (next to the pulley). The attached picture shows where the oil drop formed.

Is the vacuum pump a dismantable part? Is there an o ring that could be replaced? Is the vacuum pump available as a spare part or does it come as an assembly with the alternator only?

thanks for any help

Oil is likely coming up from the other end of that bolt.

Yes, you can reseal some of it.

What kind of seal is in there? O-ring?

Hello
I had the same problem but oil at the back of the alternator, You can get this part to fix it.
Lip Seal (alternator to vacuum pump)
Measures 17 mm x 30(37) mm x 8 mm
Nippon Denso 081103-0080
Common to a few Toyota alternators, can use Toyota p/n 29341-64130

Sorry for the Toyota bit but this should be the part.

Ian, thanks. Will contact local Toyota garage to check if they can supply that seal.

Is there some kind of seal in the front of the vacuum pump - between the pulley and the vacuum pump?
