Could very well be a broken valve spring. I had 2 go like that in mine and the second was a new one after they were all replaced when the first broke. You won't necessarily get damage when a spring breaks as the broken springs in mine simply prevented the valves from closing all the way. Maybe I'm dumb but I haven't been able to replace a spring without removing the head and I've tried lotsa different methods, Good luck

PS it could also be a head gasket !

Yes, you may have a broken spring. I would have expected you to comment on extra noise while running. The valve drops and can impact the piston. You may have a lump of carbon stuck between the valve and seat. That would just drop compression with no parts banging together. Sounds like fuel tank removal and pull the valve cover, 30 to 45 minutes should do. good luck Mike
