when breakin new engine, seem the conrod, crank shaft, piston pin and bearing got very hard stress from the very tight piston and for sure that part in the new engine will wore out a little.. is it..
so is it good idea breakin new engine
like this.. take out the new engine piston/sleeve only
and breakin it in old engine..when have finish breakin period, put back the piston/sleeve to the new engine. so ur new engine got totally no wore out part inside the engine..
