Hi Jack,
I had a feeling that was the issue. Jack, because of the miles on the present engine, I feel you would be further ahead in finding a good one with lower mileage. When you have a problem like this, almost always there are bent valves in the cylinder head which causes damage to the valve guides and the cylinder head itself.
You could remove the cylinder head for inspection. I would be happy to help you out if you want to do that.
I can't believe someone changed the timing chain without telling you there could be damage or recognizing the sound when cranking it. Ugh! I hope it wasn't too much money.
Listen, I'm here. You tell me which direction you want to go, and I'll be happy to do what I can to help.
Take care of yourself.
Joe
