Diesel Tech, have you watched the you tube clips on that 210 and Father son, with their own machine shop in Colorado,the dad overhauled it, and it went down, with number 5 and 6, badley scored and No 2 is questionable, the other 3 look very good! These are good guys, in my opinion, and they think it's the injection pumps overfueld the scored cylinders, is that even possible, I need your opinion if you have watched, the analysis of the tear down !!
 
It was not over fueling, but a timing issue. The injector pump was screwed up by a rebuilder, and they had to improvise to get it timed. The spray pattern on the pistons indicated the timing was too far advanced. The pump was sent to a different rebuilder with instructions to carefully assess it before rebuild, but that didn't happen.
 
The AC 210 has the Stanadyne/Roosa DC four roller pump with ten degrees PUMP, twenty degrees CRANK advance. Rotary pumps won't overfuel some cylinders and not others like inline injection pumps can. Piston scoring is USUALLY due to cooling issues IF the pump max fuel setting is stock. I don't recall if that engine has oil cooling spray at the bottom of the pistons, if any of those are plugged that will cause piston excess heat/scoring too.
 
The 426 Allis had 3 versions of it, this one didnt have the jets of oil shooting at the bottom of pistons, Ok thanks Diesel Tech!
