The unlucky 1%

Jake, thanks for your input.

Do you have any thoughts on where this metal disk might have come from in the engine, if it did actually come off of part of the engine? I know engines in general but I am not overly familiar with the M96 engine.

It seems that a piece of this shape could not have come from rod or crank bearings, nor does it really look like something that could have come off the timing chains.

I am really wondering if this metal disk was left over from some manufacturing process, although it does appear that it was sheared in half.

Any ideas?

Thanks

Could it be the end of the oil pressure relief piston? Might pull it to check.
