The vehicle was a Chevy Equinox, and it had an oil leak at the rear main seal of the engine. To be clear, replacing the rear main seal is a major repair in and of itself at a cost of about $1,700. The client knew the engine was leaking and kept putting more oil into the engine. That seems logical, right? Unfortunately, what she didn ’ t know is how important oil and oil pressure are to modern day engines. Despite her efforts, the oil leak was severe enough that the SUV was always running on lower-than-desired oil pressure. What do distributor caps and rotors do in ignition systems? Distributor caps and rotors are responsible for passing the voltage from the ignition coils to the engine's cylinders in order to ignite the fuel-air mixture inside and power the engine. The coil connects directly to the rotor, and the rotor spins inside the distributor cap. When the rotor's tip passes a contact on the cylinder, a high-voltage pulse travels from the coil to the cylinder via the rotor. That pulse jumps the little gap between contact and rotor and moves on to the spark plug wire, eventually igniting the spark plug on the cylinder. Because of all the high-voltage activity, the rotor and cap have to be replaced relatively frequently. They wear out easily. The distributor cap and rotor are part of the ignition system, which has to work in concert with the rest of the engine in order to ignite the fuel at the proper time. The idea is to maximize the output of the expanding gases in the engine by lighting them so that they produce heat and the fuel turns to exhaust. The exhaust increases the pressure in the cylinder and pushes the piston down. The idea is to create as much pressure as possible inside the cylinder, thereby maximizing torque and power. Plus, the more efficient the cylinders are, the better the car's mileage will be. Therefore, the real catch to the coil-distributor-cylinder system is timing. Since there's a short delay between when the spark is created and when it ignites the mixture in the cylinder, the spark has to happen before the piston reaches the top of its stroke. That way, by the time the spark arcs its way across the gap between the rotor and the cylinder, the piston will just reach the top of the stroke and the pressure will be able to build up as it descends into its power stroke.
