I suppose on the old engines it used to smash the cast steel cam shafts into 3 or 4 pieces and smash the caps.I didn't really consider the impact on the later type camshaft.I can't see any sever damage to the top of the Pistons so don't think there is damage to the piston ring grooves.What sort of psi/bar should I be seeing?.Also if injection system see's a low cylinder pressure would it shut down the injectors?
