The distributor is the device in your Oldsmobile ignition system that takes the high voltage from the ignition coil to the spark plugs in the precise firing order. One of its important components is your Oldsmobile distributor cap. Basically, it is utilized by your car engine in order to cover the distributor as well as its internal rotor. The distributor cap is one of the car components that eventually succumb to heat and vibration. The good news is that, it is also one of the easiest and inexpensive parts to replace. Generally, distributor caps should be changed during a tune up or every two years. Now, inside the distributor cap, a particular terminal that corresponds to each post as well as the plug terminals is intentionally arranged around the cap's circumference according to the firing order to send the secondary voltage to the correct spark plug at the right time. As expected, distributor caps will also fail just like the other car components. This is because of their function and location. When the bakelite housing breaks or cracks or when there is an accumulation of deposit or erosion on the metal terminal, the distributor cap will likely fail. A bad distributor cap allows the vehicle to stumble or hesitate during acceleration. For old vehicles, the recommended replacement interval of the distributor cap is at least every two years or every 15,000 miles, if not, it will create carbon tracking in the cap which will result to an engine misfire, this is also due to the high electrical currents.
