My car has been diognosed with being in the process of spinning a main bearing. I dont believe it myself. But I am getting good amounts of knock. I think it may be false because the car is a 2005 Vette with full bolt-ons and a cam. I am trying to see what I need to do to identify if the knock is in fact false or not. The car has no hesitation, stumbling, or audiable knock sounds. Can someone please look at the tune and log for me please and give their honest opinion on what could be causing the knock or how to see if it is false or not. Your help would be greatly appreciated.
