I said “junk ****” and somehow that get to that’s what Tom Lieb said.
This is how threads go sideways.
Again, as a percentage, how many of those junk cranks broke with an elastomer damper, and how many failed running a different type of damper?
I honestly have no idea, except to see the percentage of engines built with them I and certainly the lesser brands and even OE used up stuff and probably some “rebuilt” dampers certainly would be in the 90 percentile.
When I see damage like that, the LAST thing I look at is the blatantly obvious. Having autopsied many engines like that over the years, the blatantly obvious is almost never the cause.
