This is what I am looking at. Valve lash is okay on all valves afaik. Spark plugs look okay.
One bucket removed in photo, that is the right intake valve...
once you lift the buckets and the shims, how do you get at the actual valve? right now everything looks okay, not sure of whats next...
edit: reading service manual. need to pull the cylinder head to inspect valve seat. man this is a big job, lol
