Was going to check the timing. Turned the engine manually to mark timing marks. Lost focus after & tried starting the engine, forgetting that the wrench was still on the crank. It hit the lower rad hose & spun the damper bolt completly loose. It's a Fordomatic.. so I can only get about 45 lb torque before the engine turns. The manual says it needs to be 85 lb minimum. Is there a safe way to stop the engine turning? Sorry to bother people over a dumb error, but need a safe solution. Thanks..
