The 685 kit has a good reputation as a solid product.
Yet, I wonder . . . would a proper rebore, oversize factory piston and rings possibly alleviate the excessive oil consumption problem at lower cost? Maybe, re-ringing only?
The cost and effort may be close enough, the 685 kit emerges as the most sensible option.
I merely harken back to olden days, when new pistons and/or rings, and perhaps valve oil seals, were embraced as possible cures for "oil-pumpers." These considerations may be worthless, since, "That was then; this is now!"
