RidinBullets

My baby needs help! 85 turbo has always been a bullet until recent timing belt change and full tune up. Problem is she ran better than ever for 2 months and one day while driving about 35 mph heard a ticking which inside 1 minute turned to clatter on pass side head. I stopped put on trailer , in garage. I pulled front off and checked belt, all is well and still perfect in time. I need help please it hurts to see her sit.
