Topic: pistons, rings, and bore sizes...
Sorry for what is surely a stupid question for those of you who know better, but here goes:
I've trashed a couple of blocks/pistons/rods lately (3 engines in 2 events). One of the blocks looks like it'll clean up ok with an aggressive hone which may make it a couple thou larger than it should be. Could I pick through my remaining std pistons, knurl a set to expand the skirt some, and put some ebay +.-10 or +.020 rings on it (filed down to get a slight gap when shoved in the new bore?
Some made up numbers to help make things more clear:
Bore hones out to be +.005 larger than it should be when used with std pistons.
knurl std piston skirts to make them +.005 (or +.001") smaller than the new bore size
use +.010 oversized rings filed down to give minimum gap in the new bore size.
What could go wrong?
(why go through these gymnastics? It's Lemons and I can use the knurler and hone at the local junior college for free).
