Changing out the harmonic balancer on my 1999 mustang gt. While trying to get the center bolt off I twisted the pulley counter clockwise maybe 2 rotations before my gut told me to stop, googled it and about had a heart attack but I was wondering if I should really be worried and how I should play it safe(IE. should I and how would I check my timing to make sure nothing is… “messed up”). Some sources made me believe my top end was already destroyed, some implied that only if it was...

Trying to change my harmonic balancer, possible issues?
