blowit Posted August 28, 2017 Report Share Posted August 28, 2017 If you are talking about moving the top of the piston in the bore, disregard that! Very normal for the crown to be a LOT smaller than the skirts to account the heat expansion. Quote Link to comment Share on other sites More sharing options...
