Single cylinder glaze honing?

Thanks for all the comments guys; all good points. The hone for sure sounds like a bad idea, and even thougth 3M wet-or-dry retains the abrasive pretty well, there is always some residual. Considering that the engine burns about 1/2 qt of 10W30 Mobil 1 per 6-8k miles, it is not hurting for the oil rings sealing. So, I'll probably just leave it be for that reason. Pan is a bit hard to do.

Incidentally, the plug shows a bit of oil in that one cylinder, but we are finding that it seems to be coming via the intake; there is a lot oil residual goo in the intake and it is the most in that cylinder (#8) with the 2nd most in #7, also in the rear. I don't think the vehicle ever has had the PCV serviced. So, again, not likely it is this cylinder not sealing reasonably well.

Interesting thing....this one cylinder is the one where we suspect has had coolant seeping into it in small amounts for some time, and it is the one that is somewhat glazed. Perhaps tiny amounts of rust material have formed that allowed the rings/piston to finely hone the cylinder down to a semi-glazed condition.....t'would be interesting to know.....
