HI All,
One thing that is not fully understood is the Crush on shells is to make sure that the back of the shells is making Full contact with the rod I have all ways Blued the shells and check for crush, the blueing is to make sure there is 100% contact for heat transfer any thing less can be Disaster .
The only Hole I put in rods is 1.5 to 2. mm on the thrust side aimed at the underside of the Piston,
two reasons supply oil for the gudgeon and cooling for underside of piston.
Just my way of doing things
