My 1976 Dodge pickup (95K miles, 318 engine) has severe valve rattle under load or going up hills and interstate on-ramps. This only occurs after it reaches full normal operating temperature. When it is cold and warming up this does not occur and runs fine. I have tried higher octane fuel and different plugs with no change. Anything but light acceleration causes the valves to sound is if they are coming through the hood. Any help is appreciated.
have the same problem?
