Default Question about honing a cylinder

I have a 1991 Honda Civic Sedan DX 1.L. I need to do a tear down cause i am burning oil. No leaks. I have replaced the PCV valve. I am assuming the piston or piston rings. Anyway i know honing is delicate work so i was thinking using a flex hone 400 grit or 600 grit. Any thoughts? Should i go lower or higher grit?

this probably belongs in "Engine Machining & Assembly"

I've used flex hones on D-series and F-series with good results. they're easy to use and it's really all about visual inspection. if it looks good it should work fine. I'll take a look and see what grit i used and update later today.

for oil consumption from worn or stuck rings (clogged with carbon/sludge) just as important as the hone job is getting the pistons thoroughly cleaned. I have first hand experience with B-12 Chem dip and would recommend. soak them over night and they came out like new the next morning. i'm sure there are other similar products available too.

also confirm your cylinder bore taper and roundness with a dial bore gauge so you know you're working with an in-spec block.
