Hi there I recently replaced the head gaskets on my 2006 ford mustang and did the timing on it. When I put it all back in and together the engine was clicking. So I pulled the valve cover on the side it sounded like it was coning from and it clicks/jumps when turning by hand I'm pretty lost on what to do. The clicking is the tensioner catching up with a sudden jerk in the driverside cam. Any ideas on how to diagnose this problem?
