I then rebuilt what I thought would be the rings and valve seals and no luck, same problem, then today as mentioned by alot of you, was to pull a spring off , I took the spring off the offending plug, the one that was covered in oil as all other 5 were brown and clean. and even with the valve all the way up and seat, you can visably see it go back and forth, it obviously gets worse when you let it down a bit and un seat it, you can here the valve aswell when you shake it back and forth. So either way these Valves guides are shot or at least that one is, and it may only be that one, I'll find out tomorrow when I try more. But gasket wise, very unlikely when it ran for so long with no issues.

Jeff , good work, you more than likely found the problem , you should just about have no movement in the valve stem as installed in the guide, you did the test is with valve partially open that is when it really shows.. Didn't review the history carefully enough to see the intake was on for that period of time. You will be able to see into the intake ports once the head is off and make sure no other cylinders show signs of oil.

I am glad to see we have all come to a general concensus on this problem.

Good luck!
