    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!

    Why don't you take them back and make them fix their mistake?

    I am taking it back today. I'm just wondering if the oil hole is reason it needs to be on a certain way...

    I think it has to do with the way the rod bearings go on, and how the pressure on the rod bearings during the power stroke affect the thickness of the oil film on the bearing. not presonal knowledge, just relaying hearsay. :shrug:
