- Keep these bolts organized for reinstallation.
Step 6: Remove the Old Valve Cover Gaskets:
- Gently pry off the old valve cover gaskets using a flat-blade screwdriver.
- Be careful not to drop any debris into the engine.
Step 7: Clean the Valve Cover Surfaces:
- Use a clean rag to thoroughly clean the mating surfaces of the valve cover and the cylinder head.
- Remove any old gasket material or residue.
Step 8: Install the New Valve Cover Gaskets:
- Position the new valve cover gaskets on the cylinder head, ensuring they are properly seated.
Step 9: Reinstall the Valve Cover:
- Carefully place the valve cover back onto the cylinder head, aligning the bolt holes.
- Reinstall the valve cover bolts and tighten them in a criss-cross pattern to evenly distribute the pressure.
- Do not overtighten the bolts.
Step 10: Reinstall the Spark Plug Wires:
- Reattach the spark plug wires to the valve cover, ensuring they are securely connected.
Step 11: Reinstall the Engine Cover:
- Place the engine cover back on the engine.

- Refer to the vehicle's owner's manual for the exact amount of oil required.
Step 14: Check for Leaks:
- Once the oil level is correct, start the engine and let it run for a few minutes.
- Check underneath the vehicle for any oil leaks. If you notice any leaks, inspect the valve cover area and tighten any loose bolts.
Step 15: Test Drive the Vehicle:
- Take the vehicle for a short test drive to ensure there are no abnormal noises or issues.
Important Note:
Working with the engine's oil and components requires proper safety precautions and cleanliness. If you are uncomfortable with any part of this process, it's best to seek professional assistance from a qualified mechanic.
