1G Minimum Cylinder Hone - Grit

[pieceofcloth]

I picked up a vehicle that was flooded. The motor was bored .20 & the cylinder walls are in great condition still. There is a very very minor build up which I was able to clean off with a soft scrub pad. I need to hone the walls with the smallest grit. Which grit do you guys recommend? Thank you all in advance

I use a 320 grit flex hone. They also offer 400 and 600 grit if you need something even finer. 320 is what I use for glaze breaking and a freshen up. Motor seals up almost instantly. My machinist thought it was a bit coarse but my engines have never puffed any smoke after startup if even then.

I spin one in a 1/2 drill and lube it with transmission fluid as I RAPIDLY go up and down in the cylinder. If you can lay the block on its side, the fluid stays on the hone better and its my preferred method. Put a piece of masking tape on the hone shaft to show you how deep to go and just hone for about 15 seconds and check your crosshatching. It should be pretty close to 90* and the faster you move in and out the better it will look like 90*. Work a little at a time and always with fluid.

It all depends on what ring pack you’re running. Different rings require a different ra and crosshatch angle.

I would have a shop with a pressure hone see if they can clean it up. A bottle brush or 3 arm hone follows irregularities and makes them worse.
