Thanks, I'll need the help! :-)

There's also a Bosch shop in Salmon Arm, where I'm going this week, so I might 
drop in there while I'm killing time at the inlaws... they had a VW symbol on their sign, 
which is good...

Is this air driven, or mechanical? I'm not sure I've seen one of these. I assume this is 
for breaking loose small threadlocked screws?

Even if the cold start shaft isn't leaking? Is this just preventative maintenance for the 
eventual leak, or is there some other reason? I've never had a leaky pump yet, so I 
don't really know.

Why do you say this? Is it too hard on the metal? I've heard of coolant passages 
getting thin on older blocks.

Yes, it's from an '86 TD, so should be same as your Bunny Bondo.

I'll be up to my eyeballs in parts soon, so I'll just be in learning mode for the pump 
stuff until the engine rebuild is done. But my goal is to have it all ready for the May 
long weekend. (rebuild, plus swap of 2.1 wbx & 4 speed with 1.6TD & 5 speed into 
'88 Westy). I suppose I could run the engine with an NA pump for a while if I decide I 
need to rebuild the TD pump though...
