When driving my 55 F-100 with the 223 six cylinder engine, the engine develops a high pitch rattle or clatter just before I back off the throttle and shift gears. This noise does not occur under load, acceleration, or compression or when I let off in gear. I have checked and re-set the valves according to specifications. For fear of damaging the engine I have stopped driving the vehicle.
If any of you have a suggestion or have had experience with such a condition I would really appreciate any feed back from you.
Thanks in advance.
