Has anyone replaced the valve seals while the head is still on the engine???
I have only one cylinder seal is leaking.
Compression is still good and even.
Lucky it's the #4 cly that is leaking oil.
Other 5 are fine.
I do plan on changing all seals on that head.

valve guide seals or valve stem seals? IIRC the stem seals can be done with the head on as long as you prevent the valve from dropping in the engine but guide seals you're gonna be pulling the heads and going headgaskets/timing belt etc same time
