Earlier I had a post about a timing question, and eventually I found out that my crank pulley was messed up and causing my timing to be incorrect. Originally, I thought that the woodruff key was gone, but now I found it is something else. The outer ring of the pulley is loose from the inner ring. Is that the harmonic damper? Do I need to get a new pulley, and how much will it cost? Is it safe to drive for a while longer? Thanks for the help.
