I am thinking of buying this h22a short block that i pulled from car at work to make a h23vtec and the only thing wrong with the motor is it needs new rings. Now the guy i work for said that you can't hone it because they have some sort of coating on the sleves. I was just wondering if any one has heard of this and if it was true.

 

ive heard simaler things about all honda engines but have never had a problem honing one

 

I think the H series got aramid imbedded aluminum cyliders, so no. most other hondas all got iron sleeves, so can be honed.

reallly? i never knew that..

 

I don't think honing would be a problem. I just had a nikasil plated cylinder honed with no problem. They don't remove much material when they hone. They just create a new surface for the new rings to seal to. If they had to remove any extra material to remove any deep scratches they would have had to re-nikasil plate the cylinder.

Thanks for the help guys. Oh and i know you need the h23 block for the h23vtec, i pulled the h22 out because it had blown rings and i put the head off it on an h23 short block.
