Does anyone know what grit I should use. My cylinder walls are in great shape I just want to re establish the cross hatch to where it looks new. Also my cylinders are 4 inch so should I use a 4 inch or one just a tad bigger. All I could find was a 120 grit 4 inch and a 120 grit 4.125 inch. They have bigger but I would think one of those would be what I need.

I bought one from this site (Welcome To EngineHones.com) i went with the 240 grit,& the hone should be the same size as the cylinder bore.

Those are really called glaze breakers at least that is what we called them years ago. FWIW do not use motor oil with them. Motor oil will clog the surface of the stones. We used to use Varsol or some other thin solvent and got great results. Place a tub under the block and flood the cylinder with Varsol as your working the tool up and down.
