Have you tried, while runing the engine, removing one spark plug wire at a time to see if there is a noise difference...... if one piston pin or bottom bearing is loose the noise may lessen if the cylinder is not firing.

Good luck

Hi Bob

When I had this motor apart I had the valve seats done by a guy in town, he said to me , "the valve guides are rather worn, I can install new guides for $60" . I didn't get the guides done well the noisy valves are now evident , the valve stems wander around in the guides . Yes I was going to pour some oil on the whole rocker assembly while the engine was running and listen .

BTW its the original motor , still standard bore with the original pistons. The motor actually runs smoothly just a little noisy . I am tempted to remove the head and do the valve guides .
