Re: Engine/piston help
John at Just Suds May have come up trumps. Just waiting to hear if somebody a bit more local has one but I suspect I will go with Johns one.
What do you have, out of curiosity?

Re: Engine/piston help
Not sure what mileage your current short motor has?
But is it worth fitting a set of new rings?

67k on the clock on this one. Had thought aboutnew rings, however thatcould be a lot of work to no avail if there is bore damage.

Re: Engine/piston help
Take the pistons and rods out, and inspect before you write the block off?
Re: Engine/piston help
Is it breathing heavy and blowing oil out the breather pipe ?
I had a broken bottom ring (oil ring?), compression was ok, down a bit, but it blew oil into the catch tank and down on power. No bore damage just fitted a new ring on the piston. All ok after.

Re: Engine/piston help
I think Tims on the money with his suggestion. It sounds like you may have snapped a ring as you put the pistones back in. From the pictures you posted I’m doubtful the mark in the bore would cause a massive problem.
I’m assuming you positioned the gaps in each ring roughly 120deg apart ? if you were unlucky enough to install the piston with all the ring gaps lined up you could get a crankcase pressurisation problem .
