Thanks everyone...........pulley, bolt and front seal ordered. The bolt is tight so my gut tells me there is an issue w/ the rubber/harmonic balancer. Going to replace all of it, $260 will give me some pretty cheap peace of mind. Of course my mind starts wandering towards.........."Hey this is a good time to install a Eurocharged 185mm pulley........LOL". But right now the extra power is not important. Merry Christmas!
