I recommend going to
www.autopartsgiant.com to buy your timing components. I did for my rebuild.
If your damper is loose, this will allow the crank sensor gear to float between the case cover and timing chain. This will cause a scraping grinding noise as you rotate the engine. If in doubt, spend a few dollars for a new damper bolt and washer and replace it.
For new bolt torque to 89 ft pounds. loosen the bolt at least one full turn. Then torque to 39 foot pounds and then rotate another 90 degrees.
