It's difficult to cut a ring off of a liner, just because the ring is so thin. Any blade will deform and crack it, I think. Plus grinding it wouldn't be easy, because the process would also deform...

Yes, it is a bit confusing to look at this image, because of the gasket remnants and because you usually don't see open deck short blocks. But it's just a single alu-sil liner inside an alu-sil...

Because of the reduced surface area of the ring seal on the head gasket, and because it's an open deck, the leak is from the combustion chamber sideways into the coolant. And, coolant is obviously...

If there is a stop on the block, it's probably not full circle. Maybe a partial flange or a square knob. But no one so far can tell me for certain.

Yes, if you have slipped liners, but the piston rings have not come up over the liner, then you shouldn't need new pistons.

For whatever reason, diesel liners seem to be a plenty. So that good.

I have to say that this is probably not a good idea. The ID of a liner is a bit smaller than the diameter of the gasket opening. So, you'll always have a face of this ring "shim" that's exposed to...
