The timing mark will only move if the pulley (a metal-rubber-metal sandwich
that acts as a harmonic balancer) has delaminated and as such it is a Bad
Thing.
If the TDC marks align on No. 3 (as it sounds like they might) then
something is 180 degrees out, it would be a bit of a coincidence if the
pulley had slipped exactly that.
