    I'm in the process of replacing all the studs on a new build....so I have the head and jug off. ( I want to clean out the stud holes in the case) I see that the piston's bearing on the wrist pin just 'floats' back and forth out of the con rod. Not all the way off but 1/2 way. Is this normal? Doesn't seem right to me.
