Well here is where I am at with my own deal. Never got good answers on why these things are pitching rods at high rpm. I would rather deal with the valvetrain maintenance than take a chance on banging lower end parts. Looks like it would be a no brainer to go the new gen route if it were not for these things eating lower end parts with no good answer for why. Seems like some guys might have it figured out but they wont say what the problem is because they want to sell engines. Well I wont buy an engine that I know has issues and you wont tell me what the issue is and how to you fixed it.
