leaky water pump equal bad?

Check out 928 Specialists' new WP/TB kits. They're idiot proof parts selection for a good price.

I also used to keep a 2 gal jug of distilled in the trunk, and fill at each opportunity. It will overheat if stuck in traffic, but avoid stop and go, keep the heater on, and you might make it. If not, the consequences are dire. I guess you know that already.

Nothing nutty about that suggestion - it is good advice, if you choose to 'limp' on with the leak for a while. If it is a 16v euro '85, I would also pull the two top cam covers off - so you can monitor the TB, etc. If a 32v, forget it ...
BTW, on the '83 you mentioned filling the tensioner (with a syringe?) prior to the TB installation: wrong way 'round! - but OK if the bleed screw is OPENED as the belt is installed and tensioned: that will allow excess oil to escape without pushing a gasket or boot out of place . then, close the bleeder.

Sort of hate the idea of having plastic in there. How many metal impellers have eaten into the block?
I know 944 engine failure is quite common. But 928 have a lower rate of destruction on the engine per year.

Well yes to an extent.
Plastic:
Cannot hurt engine block
When it breaks, car overheats
When it breaks, bearing is theoretically still fine (is this true?)
One of the Big Three did not even return my call when mine failed (Porsche rebuilt) after about 100 miles
Metal:
Stronger, impeller does not break
Bearing does break/seize as with plastic
When it breaks, it may grind the engine block
International's pumps are all metal, and I have had great success with those.
