If you own a Ford Focus and have driven 100,000 miles, it may be time to replace the valve cover gasket. Carry out this preventative maintenance so that you don't have to worry about an oil leak or your engine smoking because the valve cover gasket is worn out. This maintenance can save you some money and headaches in the long run.
Disconnect the negative battery terminal and put this aside. Locate the valve cover gasket. Disconnect the spark plug wires from their harness by gently pulling and twisting.
Disconnect the coil plugs, wiring and remove the wiring harness. Disconnect the PCV valve and its hose. Put the PCV valve hose to one side.
Disconnect the fuel rail pressure temperature sensor from the temperature sensor array. Move the fuel throttle bracket. Remove the valve cover gasket bolts, valve cover and the old gasket.
Use car engine cleaner to remove any particles that are left from the old gasket in the gasket seating area. Put in the new gasket.
Place the parts back on the motor that were removed initially, starting with the valve cover. Once the cover has been replaced, tighten the valve cover bolts in sequence. Put the fuel throttle bracket back. Reconnect the fuel rail pressure temperature sensor back on to the sensor. Reconnect the PCV valve and its hose, coil plugs, wiring and the wiring harness. Reconnect the spark plug wires to the harness and reconnect the battery terminal.
