deglazing

[PatG]

I am going to re-ring a 350 that was rebuilt about 7 years ago. I am not sure of the reason but the rings seem to have never seated on this motor and oil consumption is high with smoke on accelleration. So, I am looking for advice on the correct tools and procedure for deglazing the bores. I have found places to purchase a "flex" hone or "dingleberry" hone. For instance here

So here are the questions I have concerning this matter:

1. What is the correct grit of hone to use?
2. What speed should the hone be run at?
3. Is 30 deg. the correct cross hatch for this procedure?
4. How long do I run the hone or is it done by look?
5. What is the correct lubricant to use for this type of honing?
6. Is there a best manufacturer for this type of hone?

Any other comments on ring seating would be welcome. The motor was bored .030 over and the rebuild used Childs & Albert Cr-Moly rings.

Here would be some interesting reading for you. You'll need Adobe Acrobat to read the pdf.

And then this for the break in (might give you some clues as to why the walls glazed over last time).

Thanks for the replies Bob, especially the break in procedure. Perhaps I was too easy on the motor on the first go round.

I should have also mentioned in my first post that this motor has less than 10K miles on it.
