a little light oil on the shaft and some contact cement or gaska-cinch on the outer diameter and it seals best. install while the cement is still wet.

another bottoming tool for the autistic mechanic installs the belt cog prefectly

the water pump was leaking too

and behind the pump manifold three o-rings died of old age

this all cleaned up fine, after i knocked the old seals out

now I am waiting on the cam seal tools and viton o-rings - the dealer ones dont fit well.
