I've seen ring lands broke loose from pistons caused by ether in Japanese engines. The explosion is too much for them if the rings are spaced close together.
I've replaced many overheated/'burnt-out' starters... and they were almost always the starters that are really hard to replace... and solenoid contact points and conductor disks that were eroded or fused together...
farm i took care of once upon a time had a ford 1000 2 cylinder jap diesel if i was in a hurry which was rare . and didnt want to gag on the exhuast while it was triing to get running on both cylinders i would glow plug it start it then get off and literly put a couple dropps of either on a corner of paper towel and just wave it near the air filter inlet that was enough to make it hit on both cylinders and clear the exhuast to get it backed out of the building , or while it was triing to run i would turn key backwards again for a few seconds at a time to rewarm the glow pluggs not sure that was good for it so didnt do that much .had a half can of ether with almost no propellant in it last me over 6 years doing that , he used to buy a 3 cans a winter , now i know what happened to the piston ringsI have always been more afraid to use it on little Japanese or Ford-IH 20:1 or greater compression engines than on lower compression turbo engines for fear of what it will do to the wimpy pistons. Although sometimes you do what you have to.
Another rule to live by, if you have an engine under warranty if it took ether to get it going don't tell anybody, we all know how they love to use any excuse to deny warranty.
Over revved engines drop valves and break rod bolts. Busted rings are usually from worn out cylinders, dripping injectors and ether.
