Doing the water pump job? new pump and reusing the back cover. I have the gasket from Dgo and it actually came with two - one is black the other cardboard? both feel like the same material otherwise. Which one do I use (assuming I only use one)? And, would I smear hylomar on both sides of the gasket when installing?
Unrelated to the above, for the intake manifold gaskets (the 2 at the top facing the rear of the car) I assume those just go on dry?
