Re: Rings busted, need short motor, engine overheated? WTF?
Hi
I think I finally worked out what it is that seems strange.
As the pistons go up and down the area above the top piston ring does not wear as nothing is touching it. It also gets carboned up and gets blackened.
This is where it seems strange. I am sure that there are cross hatch marks on TOP of the unworn but carbon heat marked top of the bore. It looks like cross hatching extends from the wear area into the non wear area.
From the photo I would suggest it has been honed after running (after the factory).
cheers
