Does any body know what would cause an engine to fail, with the top
half of the connnecting rod bursting out of the crank case, so leaving
a big hole in it.The two big end bolts shared off; leaving broken
halves in the rod and the bolt head half in the sump.The piston was
smashed to pieces;breaking the gudgeon pin boss into two half,and the
top half of the gudgeon pin to the crown, also broken into two halves
along the weaker part of the piston; that is at right angle to the
boss.
