The waterpump body is pristine,but the impeller is siezed. VW heads, obvious sealant squeeze out on gasket. It is the pushrod tube condition that is a bit unusual, nice and shiny.

I'll set up spare bellhousing and do comp test, and hook up some air to do leak down test.

A couple of poor quality pics (GoPro vid cam, not the best for thing) to give an idea of how it looks
