I just replaced the valve cover gaskets on a 93 Corsica with the 3.1 V6 engine. The front valve cover was not to bad since it is easily accessible. The rear valve cover took quite a bit more work. Here are the steps that I followed.
Bear in mind that this was the first time I had attempted this and I did not have a service manual. This may not be the technically correct way to replace the rear valve cover.
1. Unbolt the alternator and move it aside. ( I was able to lay it on the front of the engine to keep it out of the way.
2. Unbolt and remove the upper engine mount from the engine and the body. (the upper mount is the alumium piece that connects the upper front of the engine to the passenger side inner fender wall.)
3. "Roll" the engine forward. I connected a come-a-long to the back engine lifting eye and pulled the engine forward. (I pulled against the sturdy bench in my garage).
4. Mark and disconnect the throttle, cruise, and transmission kick-down linkages from the upper rear of the intake manifold.
5. Disconnect the power brake booster vacuum line.
6. Mark anc disconnect the vacuum lines to the bracket at the back of the intake. I am not sure what it is called. It is a plastic module mounted to metal bracket that retains the throttle, cruise, and transmission kick down linkage cables. BE CAREFULL with the vacuum lines. The hard plastic lines on this 93 were brittle and I broke two of them. I had to unbolt the intake manifold and splice the plastic hard lines back together using 5/32" vacuum line.
7. Remove the bracket that holds the throttle, cruise, and transmission kick down linkages.
8. Mark and remove the rear spark plug wires. While the spark plugs are accessible, I would change the plugs and wires.
9. Remove the alternator braket and the front engine lift eye (Both are attached with the same bolts)
10. Disconnect the Power Steering return line.
11. Now it should be possible to loosen the four bolts that hold the valve cover on.
Reverse procedure to reassemble.
yes you have to change the pan gasket when doing the timing chain
how to change timing cover gasket on a 1996 chevy lumina
When you change the timing belt inspect the tenstioner. If it is not in perfect condition replace it.
there are two tensioners, the serpentine tensioner and the timing belt tensioner. the timing belt tensioner is behind the timing belt cover ;)
Not unless they are damaged or faulty.
60 ,000 MILES , YOU MUST ALSO CHANGE THE TIMING BELT TENSIONER EVERY TIME
No absolutely not...
you must remove the timing chain and head. This will then give you access to the head gasket
In order to change the timing belt in your PT Cruiser you will need the new tensioner and timing belt covers. Your dealership should have the parts you need
It will take an experience mechanic approximately 8 hours to replace the timing belt in your 1992 Chevy Corsica. The 1992 Chevy Corsica does not have each timing chain, it has a timing belt.
1.4 Eight valve engine. The water pump is the timing belt tensioner on this model. you need to slacken the pump and rotate it to tension the belt.
Removal of the timing chain cover, timing chain, and head are needed
