trusty rusty ED6
title says it all. crank pulley started wobbling the other day. not sure why. car still runs well enough. i can hear it rubbing when i'm sitting in the driver's seat but only at idle. full disclosure: i'm still learning the finesse of shifting a manual trans so i've had a couple unintentionally aggressive launches but nothing that would spin the tires or anything. and i'm almost 100% sure i haven't over-revved it (no tach so can't be sure) it's a d15b1 block with a d15b head. i really don't know why it would start wobbling like that. any ideas?? and besides getting a new pulley, anything i should be worried about? would driving it cause more problems or should i keep it parked till it's fixed?? i know some of these questions are noobish, but this has got me pretty confused.
