But it takes two people. Unless you have an inspection camera. Pull off your distributor cap. Get a 1-1/8 socket, and breaker bar. Put the socket on the bolt that's holding the crankshaft harmonic dampener on. Rotate the crankshaft clockwise a little. Then rotate the crank counterclockwise. As it just starts to rotate in the counterclockwise direction. Use a hammer to tape on something to indicate when the crank started to turn. The person that's watching the distributor rotor then can note if there is any delay between the tap, and the movement of the rotor. The amount of delay will give you an IDEA of the condition of the cam chain. There should be no delay. Using an inspection camera for the person doing the rotating while looking at the rotor with the camera is best. These cameras are to me a must have tool. Bob Dunahugh
