…the rings come out like this:
Cue CCR’s Bad Moon Rising. In this thread: Harbingers of doom.
I’m not much of an engineer but looking at the picture, is it possible that the wrong tools were used?
just a thought.
Don’t force it; use a bigger hammer.
The liner probably doesn’t look that good either but if you get the tip of that electrical insulated screwdriver straighten out it’s a keeper. The tips of mine usually snap off after a couple of whacks.
your workbench is dirty
The story goes that someone put this engine together with a head gasket leak big enough to hydrolock it. It then sat for a couple of years full of sea water before I came around. To be honest, I didn’t need the broken rings to tell me that I was getting into trouble.
Actually, the bores aren’t as horrible as I feared, and may be saved with stress honing. Broken screwdrivers are one of the most precious commodities around the workshop, and I guard mine jealously. There is no end to the useful tools you can craft from a high quality screwdriver.
Once the rings have rusted well into the grooves, I’m not sure that there is a right tool for the job. My only concern at that stage is to save the pistons, and using a round drift that fits into the groove is at least somewhat effective at chipping out the rings. In the undying words of John Drury Clark:
For dealing with this situation, I have always recommended a good pair of running shoes
However, there is no running away from a trade-in :-/
