Doesn't look good either

Looks worse with all the soot and crud removed
Out she comes



Just like Meccano

I’m not surprised, although one must ask themselves where the missing piece is ?

Do you have enough bore material to go oversize ?

Is that a chunk OT of the piston top edge?

Merely a flesh wound…

Found the problem, the top ring has decided to go on holidays

The hole in the piston may or may not explain why she was puking out oil at a prodigious rate for the last hour of her life …..



Some of it decided to hang around in the oil ring

Bore is not too horrible so just chuck a set of rings on this piston and send it


…… or maybe it’s time for a new one

This block is cactus anyway, has cracks between the head bolt holes and the water jacket - is +.040” so won’t clean up at 60 so in the bin it goes.
Will reuse head, oil pump and some bolt ons but that’s about it

Oh dearie me! You've managed to get by on 5 1/2 cylinders for a good many miles. Soldier on!

Big ends are .030” so crank may be a bin job as well …. Will have a look inside the oil pump tomorrow and see if it can go around again

Hmmmm …. That engine is not looking good
