RE: Need a little p.a.w. advice
Just wondering if the rod could be in backwards?
Most rods have a radius at the front of the journal that matches the radius on the crank pin/web joint and when you put the rod in backwards a square edge then gets presented to it .
This results in the rod wanting to walk off the back of the crank pin as it tries to get away from the crank pins radius to only ride on the flat of the pin.
Having one head bolt tight and the other two loose is not good as you are using two wrongs to make a right and actually goes against what Lou advised.
