How to "de-glaze" the H22 cylinder walls

If your cylinder walls are in generally good condition ie no large vertical score marks etc then you don't really need to "hone" the block as such. This is for deglazing rather than specific honing (to go oversize, after rebore or to eliminate scoring marks. All you are looking to do is "de-glaze" the cylinder walls gently to allow the new rings something to bed in against.
The FRM cylinder walls are VERY easy to screw up so hard or heavy grit stones are a big no no.
The actual proper honing process (which would really only need to be done to remove markings or after a rebore) is very tricky and very few places are capable of doing this work to the exacting standards required. PerformanceAutoworks are one of those places that can do this if required
Hand de-glaze using 600 grit wet and dry and lots of WD40 as lubricant and to stop clogging and possible scratching of the bores. this should be done with light hand pressure working around the bore in large sweeps and gradually dropping down the bore while still working in a circular motion. I obviously can't explain the exact amount of pressure to use as this comes from experience but you don't need much !
If you have a block to practice on, use it as it takes some of the worry out of doing it to your good block without practice!
As you will see when you have a practice it doesn't take too much pressure but just try to get an even finish around the bore over it's full depth as well.
