Finally got to replacing the tensionsers today. The LH tensioner, front of the engine, is bear to get to!

After removing the tensioner I can not find any gasket ring. I scraped the area on the block carefully with a small screwdriver and am not seeing or feeling a gasket ring. Is it in a counterbore?

I purchase (2) new gasket rings with the Ford tensioners and am puzzled.

Also, I am seeing that if you pre-prime them they can be difficult to install. Some saying that they messed-up the port threads. Should I pre-prime? I really don't want to have to do this two times.

Thanks.
