Solution

1. Preparation

Gather tools and materials needed for the repair.
Ensure the vehicle is parked on a level surface and the engine is cooled down.
Disconnect the negative battery terminal.

2. Inspect and Replace Gaskets

Valve Cover Gasket:
- Remove any components obstructing access to the valve cover.
- Unscrew the valve cover bolts using a socket wrench.
- Carefully lift the valve cover, inspecting the old gasket for wear.
- Clean the mating surfaces with a gasket scraper and solvent.
- Install the new valve cover gasket, ensuring proper alignment.
- Reattach the valve cover and torque the bolts to the manufacturer's specification (typically 8-10 ft-lbs).
Oil Filter:
- Locate the oil filter and inspect it for leaks.
- If damaged, remove the old oil filter using an oil filter wrench.
- Apply a thin layer of fresh oil to the rubber gasket of the new filter.
- Install the new oil filter, hand-tightening it securely.

3. Check and Refill Engine Oil

Remove the dipstick and wipe it clean.
Insert the dipstick back and pull it out to check the oil level.
If low, add the appropriate type of engine oil (5W-20 or as specified in the owner’s manual) until the correct level is reached.
Start the engine and let it idle for a few minutes; check for leaks around the valve cover and oil filter.
