my mechanic told me that my crankshaft pulley is damaged because a rubber piece in the middle if it has worn out. he says hes never heard of this thing happening and that i would have to repace the whole pulley. i looked aonline a bit, and all i could find was this ruuber seal part of the pulley. has anyone ever heard of this, or know whats going on. and if it is broken do i have to replace the whole thing? thanks in advance darren. btw, if it is broken ill be needing a new one. so if you got one laying around after an afertmarket upgrade, let me know that too.
