Piston Movement (bushings?)
Currently doing a rebuild on a 951 engine, I've noticed that the piston tops will jiggle around a bit on the rod. Not a whole lot, just enough to be noticeable. Think some new pin bushings would fix this or am I over/underestimating this?

There should be .001-.002" of clearance in the pin/piston (perfectly clean...no oil on either)... less than a human hair. With oil, there should be ~no movement.
The very slight space is so oil can get in there.
