I just got my P30 pistons pressed onto a set of LS rods, and the idiot at the machine shop put one of them on backwards. In other words, the PR4 on the side of the rod is not on the same side as the arrow on the top of the piston. I think this will cause a problem because the oil hole in the rod is now on the wrong side. Can someone please confirm this? That guy's a fucking idiot!
