When I cranked the engine, I see unusual rings near the top of #1 and #6 cyl. Cannot feel them. Any ideas on the cause of this anomaly????? Attach file:   (38.24 KB) Posted on: 2014/6/25 22:34

Hone or bore out cylinders? Sand the head to remove rust? Pull and replace the studs?` Always puzzled when I see an engine that has been sitting around opened up.... Posted on: 2014/6/25 23:55

This project will slowly bubble up on the priority list. Thanks for looking... Bob and Gail Posted on: 2014/6/28 10:43

If it is 1xxx6xxx then most likely nothing to worry about. The engine just sat for a long time. I would definately mic the cylinders tho. Posted on: 2014/6/28 14:20

Bore looks smooth so would advise a hone if it is not worn beyond spec. If you can't feel the marks then it's likely they won't cause any damage to the rings. Posted on: 2014/6/28 18:20
