so i went to the drag strip a few days ago truck sounded good. when i left the track i notice the truck had a louder knocking sound. its all the time, in park or driving. my buddys said i was hearing things but once we got home and they heard it standing outside they all agreed it def has a knock. sounds like a rod bearing type of knock. for some reason my tech 2 wont give me balance rates so i dont have that info yet. does not smoke at all, runs like it did when i left home. turning off injector 1 seems to make the most effect on the sound. seems to deaden the knock. i have stock push rods, is it possible that one could be bent just a little causing the sound or does anyone have any better ideas?
