Thread: Td5 vacuum pump leaking oil

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

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?
