Pieces of steel in cylinder??

I get a chuckle out of people going down the Sabotage path.

Can look up melted bearings on google and see stuff like that. Surprising that the crankshaft did not get the bearing alloy transfered on to it, was expecting to see that. Guess he shut it down just in time before the crank went down.

You might be right, but I find it telling that no one so far has been able to say ...

"This is what happened and this is how, because I've seen this exact thing under these conditions...."

It could still be a product of some chemical reaction. either some additive poured in by mistake, on purpose or by someone who really knew what they were doing. At this point, no one knows for sure.

I'm the first to agree that I've only seen a few spun bearings but it seems to be there would be much more scoring if there was enough heat to melt (or soften) a bearing to that point. No? I dunno...

Could it be innocent? Sure, of course. The other options are still on the table until there is a definitive answer. The easy way to see what that metal is, is to melt it down and observe it closely. See how it behaves and when it melts. If it melts below 200C, it's likely an alloy that's meant to melt at low temps..

I do find this all extremely interesting...
