my two pence worth. how about the merlin engine as fitted in the spitfire, hurricane, mustang and lancaster? still used today in prop aircraft racing - awesome.
at the other end of the spectrum the honda horizontal engine as used in c90s etc is, i believe, the most produced engine of all time. they just keep going.
for car engines the mercedes 601 to 606 series diesel engines just keep going, i know one coming up for 500,000 miles!!!
