    Okay, I recently bought the 7.3 idi (because where I live, they don't have taxes because they are old.) Anyway, when I start the engine, it sounds fine. There is no "huge knock" when I rev, it's quite a small knock. However, when I engage the transmission, there is knocking coming from the driver side. If I press the pedal it knock even louder, but it stop when I remove my foot from the throttle. This is killing me, could it be a rod? Injector? Manifold leak? I can't seems to figure out myself. I need your help guys!

    Oh I almost forgot, the temp never seem to go higher than the minimum (it start below the minimum)...

    Also, a guy here posted a video of his truck and mine is doing the same sound (but it's more quiet than his without an engine load)

    Pull the driver's side valve cover & check the push rods and rocker arms.
