I can provide a seal part number to anybody that would like, just send me a PM.

I was unaware of any debate. I don't know of anyone that thinks it's a bad idea. I could be wrong.
Me I don't have seals cause there's been no compelling reason to rip into the engine for just that. But........... now I may have another unrelated issue so maybe I'll get the seals in.
What's that part # and how do they hold down if there is no machined grove?
