HEADLAMP ACTUATOR VACUUM LEAKS
All Corvettes from 1968-1981 can have a large vacuum leak from the headlight actuator vacuum system that will affect the engine idle. When experiencing rough idle, remove the vacuum hose and plug the fitting temporarily, then check engine performance. See Transmission Modulator Vacuum Leaks above for additional information.
The rubber hoses and other components of the headlight vacuum system are known to wear out. In many instances, only one of the headlight assemblies will operate. Always check all rubber vacuum lines when even a single headlight assembly is not operating properly as many times, it the result of a failed or collapsed line.
Over time, the door hinges on all C3 Corvettes fatigue and begin to fail, causing the doors to sag and other alignment issues including broken door seals, water leaks, and road noise. To prolong the hinge life, lubricate the hinges regularly. In the event that the hinges do sag, replacing the hinge bushings and pin is also an option, although replacing the upper hinge pin will require the removal of the dashboard speedometer cluster.
