I have posted a similar message on sol so you might have read
more or less the same thing already. For those you you, my apologies.
I understand that there is a honing process called extrude hone,
wherein you get a hydraulic press to push a viscous goo saturated with
abrasives through an orifice. I have read glowing comments of improved
fuel efficiency and lower CO emmissions as a result of getting this
process to work on the intake and exhaust manifolds.
Have anyone on this list done any work using this process? If so, what
have been your experience with the process and its results?
