idle rocking/tapping
 

97 eclipse gst m/t. There is a tapping/rocking noise coming from the back of the engine near the bottom closest to the balance shaft belt. Ive noticed the noise after timing belt change checked timing and its set right on. I don't hear it when reving the engine but at idle, sometime here and there once in a while. Ill take videos and upload them sometime later. Thanks to all.
