Single cylinder glaze honing?

nm9stheham said

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.....

I would bet that the leaking coolant into that cylinder washed the oil off the walls and caused it to wear more. Ie. glazing.

I would make sure to fix the coolant leak to keep it from getting worse.



Why not get a 4" wire wheel on a drill and clean up the cylinder as good as you can with it? I've don this with many engines that have sat open with the head off and got some surface rust on the bores. . Then put the piston at TDC and clean it with rags, then compressed air until all is clean if you don't want to pull it.

Or use some of the "Scotch Brite pads" to clean up the surface as they don't have any abrasive grit to fall off and get into the cylinder.
