Phat VR6 3 Posted February 16, 2009 Report Share Posted February 16, 2009 A quick trick is to pull the spark plug leads off one buy one, and replace... while running.If the noise gets quieter when you pull a certain lead then its that big end that's knocking.You gotta drop the sump and inspect bearings if it sounds like its coming from the bottom end, Can you tell from listening if its coming from the top or bottom?
