Is there an O ring seal between the valve guide and head?
No o-ring.Is there an O ring seal between the valve guide and head?
I have not.Like this one. Ever see one leak?
Well sumbich. Never knew that. I've replaced guides on literally dozens of different types of motors. Never seen even one with an o-ring in there. They're an interference/press fit. What's the point?
Agree.I am not convinced that the O ring is needed considering that you have to heat the head pretty hot to loosen the guides and they still need to be driven out. Also the contact area of the guide and head is quite long. Just my thoughts other posters will have different ideas.
