Interesting ? When breaking in a fresh/new motor what are we actually breaking in? Do crankshaft bearings need breaking in? Camshaft bearings? Valves & valve guides? Piston/rings & bores(cylinders) Do roller bearings need a break in period like big end & main bearings in 427 chev? If not are we actually doing any harm to the rest of the motor while breaking in a new set of pistons/rings and bores.I would be interested to know/debate anyones thoughts.
