Harmonic Balancer Help!!!
Please help me. My truck had a weird thumping sound only through the exhaust. It sounds as if it thumps once per revolution. I've asked around and have recieved many things. I've been told the harmonic balancer could be bad and throwing off the balance. Other said it could be a bad injector but I do not have smoking or lack of power or even a miss. Last I've been told it could be a valve train issue such as lifter, pushrods or valve/valve guide. The motor runs mint and doesn't shake or miss. Just has the thump through the exhaust. No lack of power what so ever. One thing that makes me believe is when I rev it in neutral it will shake on and off. The balancer is pretty wavy past the rubber. Please answer if you've had this issue. I'm replacing the balancer and pulls tomorrow. Thanks.
