I mean with all the testing that must or does go on I would think the manufacturers would have told us if this above stated method would be the proper way to break -in ! In fact does anyone know what the race car drivers/teams do for Nascar or Indy types or are those race engines "pre-Broken in" before dropping in ???
An automobile engine is a 4-stroke engine. It has an intake (induction), compression, power (combustion) and exhaust stroke.
The
two-stroke cycle is usually used by lawnwowers and motorcycles. It completes the same four operations (intake, compression, power, exhaust) in only two strokes (linear movements of the piston) rather than four. Thus, there is a power stroke per piston for every engine revolution, instead of every second revolution.
I agree that it would be interesting to know how NASCAR engines are broken-in.
