4pursells Posted May 25, 2004 Report Share Posted May 25, 2004 As suggested the other day I removed serpentine belt to help determine if the main bearing is at fault. Upon removal, it seemed that the thumping, banging was more pronounced. This noise only happens for instance, when the car is in park and I give it a little gas or when accelerating from a stop. ( When standing over the engine, hand placed on top, you can really hear and feel the bang). Otherwise, the engine sounds great. Isn`t the main bearing thump supposed to disappear when the belt is loosened or removed. Could I have a serious problem? Link to comment Share on other sites More sharing options...
