I replaced the tensioner rail, gaskets and seal. I did have a problem replacing the harmonic balancer. When I pushed the balancer over the crankshaft, the woodruff key got pushed out and against the new seal causing a small hole and oil leak. Had to redo it. Was able to remove the timing cover by the lifting the engine with a floor jack and block of wood. Put a small piece of 2x4 under the engine mounts. This project took about 16 hours. Also, a new valve cover appears to have cured the oil leak. Car back on road and running ok.
