piston pins...

Just make sure you don't get the pistons backwards on the rods, or the
rods backwards in the block and that the ring gaps are staggered.



Not sure if the six is  the same, but on the V8 you tighten the nut down and
then use a hammer  or hammer and punch to smack the back side of the clamp
screw.  This seats it better and the nut on the other side will move some
more when tightened to the same torque. Repeat till the nut will not move
when tightened to the same torque.
