I'm about to replace my rear shock absorbers and while I'm in there I want to address a long standing oil leak at the turbo scavenger pump. Does anyone have an exploded view showing what seals the bottom pipe joint? I think that's the source of my leak.

Wish I could help. I need to address my scavenger pump, too. I saw a couple decent threads about the scavenge pump - but can't recall if it was here or PP. I think it was here...

Please post up your DIY and offer tips for those of us doing this soon - thanks :-)

John it's two aluminum washers, 20 mm o.d. by 16 mm i.d.
Install new and torque down nice and it should solve your problem.

Paul, I have my parts. Is it that simple?

John, if your going that far you are missing the seal (part 33) for the camshaft. To install it you have to knock the drive pin out of the pump shaft, install the seal (carefully; I ripped one carelessly the first time I did it) and install a new pin which you cannot source from the factory.

Paul, I thought I would do the banjo joint first then go deeper if the leak is in the gasket etc.

You might want to spray the area with brake cleaner to more accurately trace the leak, but in looking more closely at the picture you posted, you may be indeed going deeper.
If the shaft seals are bad the oil will be coming from under the pump cover (part 39). If you need to go deeper, you will also need part 34, which is the camshaft seal. Be sure to apply some Curl-T to both sides of the paper gasket (part 42).
