My 410 was originally built using a cracked cylinder head (around #6 valveseat), which pressurized my cooling system. So, I yanked the engine and my builders tore it down, changed the bearings (I think), rehoned the cylinders, put on the new heads, etc. Then, apparently, the rings never seated. Runs good, made the dyno numbers in my sig and gallery, but it burns a quart of oil about every 250 miles and oils the plugs. My builders are gonna swap everything over to another block (for free).
Do you think this additional honing had anything to do with the failure of the rings to seat?
And, Joshua, I'm curious as to why you're curious about this.
