OK, Thom, I'll jump over here! Have you run a compression test on #4 after adding a tbl or so of oil in the sparkplug hole? That SHOULD tell you if the compression problem is valves or rings, etc. If compression improves with the oil, it generally indicates a top end problem. Valve adjustment might help.
