i have a d15b non v-tec and ive been hearing this ticking noise for some bit. i thought it just needed a valve adjustment so i did that then i realize it was my crank pulley making all that sound. it moves side to side when it rotates. what can cause that? Thanx in advance.

 

Is it loose? The crank pulley bolt should be torqued down pretty damn tight.

 

130 pounds?
