Crossflow problems
Stripped the head off the crossflow after it developed and metallic banging everything looked OK except number 4 piston had been banging against the
head? both head and piston having matching 'polished' areas where there is no carbon. every other cylinder has a good coating of carbon.
It didn't sound like bigends. what do you reckon? broken end cap bolt allowing the end to open up enough to hit the head.
Will find out this weekend in the meantime anyone got a crossflow lump they don't need? 
Cheers Alan

Polished as in steam cleaned polished or contact polished?
If contact polished then suspect little end bearing.

Beware of the Goldfish in the tulip mines. The ONLY defence against them is smoking peanut butter sandwiches.

 We had that happen once - found little dents all over the top of the piston. After pulling the piston, found a 1/8" long piece had broken
off the end of one of the compression rings. No other damage - just rotated the ring a little by hand, screwed it all back together, used it for
several years (including racing) after with no ill effects!

Big end bearing is run -- probably be gone for while and hammered the bearing shell.

If so, your big end bearing has broken up.
