Good Morning,
Quick back story. 15 years ago I had the rebuilt on my '47 A when I replaced the head gasket. The new head gasket didn't solve my problem so it got tucked away until now. I don't think the valve job has more then 10 hours on it, at the very most 15.
Fast forward to today. Complete engine overhaul. Last night I removed the valves as I was going to have the shop machine shop run the head through their parts washer (it's been sitting for a long time and was pretty grimy). This is what I found:
This is the worst of the bunch, it's kind of hard to see in the picture but the you can only see the ring on about 2/3s of the exhaust valve face, the rest is just soot. There at least one other like this as well but not quite as bad. The intake valves look OK.
What would cause that? Did I get a poorly done valve job?
