OK, go ahead and blast me for his one; I fully expect it. Having wet sanded with water many times and getting a great finish, I wonder why we couldn't hone cylinders using water instead of oil or dry?

Water + cast iron = RUST

honing produces alot of heat. oil is used to carry away the heat and the particles of metal so your cylinders dont glaze. and rust sucks

Thanks, I needed that

To be the contrarian here, when we finish honing we wash the bore with soap and

water. Of course we don't leave it like that for it to rust away, we coat it with oil. Why couldn't the same thing be done after honing with water?

the honing process is not meant to leave a perfectly smooth finish. it is meant to have a rougher crosshatch to enable proper ring seating. oil is friendly to the tooling and, yes, does not rust.

Clickhere33 is correct.

Another point is the oil helps flush the stones and keep them from clogging up. Sunnen even makes their own oil just for this. It's different than motor oil, it's more like a cutting oil.

Yup, it's called honing oil LOL. WD-40 or standard motor oil works fine though.

We use a mixture of water and oil when honing. We have found it to leave the best results in the cylinders when done.

How do you feel about dry honing? I dry-honed cylinders for years before I heard about honing oil. It's amusing that what worked fine years ago is now considered herecy

moparzrule · 05-05-2005, 07:12 AM

Did you use a bottle hone or the hone with 3 long stones on it?

John B · 05-05-2005, 08:25 AM

I use a Lisle 15000 micrometer head to rough size the bore and then a 320 flex hone to plateau hone. I know many feel that 320 is too fine, but that's a whole different issue.

Andre Parker · 05-06-2005, 02:12 AM

I've always used Sunnen machines. Never had a problem.

Excellent hone. I wanted a Sunnen but the cost was out of my reach. The Lisle does a good job too.
