I am about to do the water pump, while I am also doing the plenum seals. I pulled off the top housing off the water pump, the one that has the hose from the top of the radiator and also the hose going into the intake manifold.

Since I have the parts pulled, I decided to clean up that housing. As I soaked it and then rinsed it, a piece of rubber type gasket compound came off.

What?

This part has never been renewed, it is original. It seems that they felt the paper gasket was not enough of a seal, and added some gasket-maker to this mix. Not a thing mentioned in the manual of using a suitable gasket making compound, yet at the factory they obviously did.

What do you make of that???
