Ok so whats the procedure for flexhoning an engine block? My guess is lube the flexhone and cylinder walls with engine oil and make 15-20 quicks passes up and down with the hone. Am i right?

Not worried about cross hatch angle?

Yep, that's about it. You can get a recommended honing fluid from BRM, which is the company that make the Flex Hone brushes.

yea flex hone 400 grit hones are the way to go!!! you can just use ATF trans fluid because its the same viscosity as the stuff they try to sell you with the hone...im waiting for mine in the mail now

Just make sure you bolt down a torque plate first if your honing an LS Alloy block or expect it to warp when honing.

flex hone doesnt even take off a significant enough of material to require a torque plate...its just to get a good cross hatch for rings to seal...no even close to taking off one thousandth of an inch, and if it is you are either using wrong grit, or making over 50 passes with the thing

Really? The torque plate is installed to prevent warpage during honing?

i thought 240 grit was the recommended grit to use?

i bought a 4" 240 flex hone, is 4" the right size....seems kinda big

Mano suggested 400 grit, I would think you'd be fine as long as you don't go over board...just do enough to get good cross hatch
