Timing problem we think?


Mark the timing belt as well with the marks on the crank and cam.
to make sure it is not slipping and staying in place during the install.
I hope your valves are not bent. If they are not and you checked the above and still the same, then and only then I would put the belt back the way it was with that tooth off.

I have a 1999 Mitsubishi Galant and need to know how to put on a valve cover gasket. Oil is leaking out and dripping and it's causing it to burn and smoke comes out of the car.


Instructions
    • 1 Allow the car to cool. Disconnect the battery terminal. Remove the right side vent screen top extension. Disconnect the ignition coil with power transistor and its wiring and brackets.
    • 2 Disconnect the left hand side coil wires and spark plug wires. Remove the spark plug wires, valve cover bolts and the valve cover. Unplug the electrical connections from the intake manifold runner control actuator. Unfasten the actuator retaining the screws, right bank heated oxygen sensor front and rear.
    • 3 Remove the heated positive crankcase ventilation (PCV) valve. Remove the heated oxygen sensor plug and the Differential Pressure Feedback EGR (DPFE) sensor. Disconnect the ignition coil with power transistor and its wiring and bracket. Remove the valve cover bolts, the valve cover and the old valve cover gasket. Clean the valve cover seating area with automotive engine cleaner and place the new gasket in the gasket seating area.
    • 4 Replace the parts that were removed and disconnected by reversing the steps. Replace the valve cover gasket and tighten the bolts, in sequence, ensuring not to over tighten. Put back the ignition coil with power transistor and its wiring and bracket, the heated positive crankcase ventilation (PCV) valve, the heated oxygen sensor plug and the Differential Pressure Feedback EGR (DPFE) sensor.
    • 5 Add oil to the car. Start the car and let it run at idle for a while to check for leaks..

I want to change the valve gasket. I see 2 bolt on the top of it can i do it for myself. im wondering maybe there is some parts attach to it. mitsubishi galant 79 model.


Hi,
That two bolts is the one holding the valve cover and the air filter housing.
No worries, just remove the bolts, and remove the old gasket around the cover.
Upon installing new rubber gasket, make sure it is clean. Put a silicone sealant around the canal, where the new rubber gasket would be placed, not too much sealant.
Put the new gasket, and now you can put back everything as you have removed it.
Hope that seals everything!
Thanks for using Fixya!

We have oil in the spark plug wells


Most likely you have a leaking valve cover gasket. There is a gasket the goes around the valve cover, and also a gasket where the cover mates to the head for the spark plug holes.

you need to replace your valve cover gaskets. There's oil seals under the valve cover gaskets that leak causing oil to get around your plug wires.
