- Remove any components obstructing access to the valve cover.
- Unscrew the valve cover bolts and carefully lift the cover.
- Remove the old gasket and clean the surfaces.
- Apply a new valve cover gasket and reassemble the cover, tightening bolts to the manufacturer’s torque specifications.
Oil Pan Gasket:
- Drain the engine oil and remove the oil pan bolts.
- Gently tap the oil pan to break the seal and remove it.
- Clean the oil pan and engine block mating surfaces.
- Install a new oil pan gasket and reattach the oil pan with the specified torque.

4. Replace Oil Filter and Add New Oil

Remove the old oil filter using an oil filter wrench.
Apply a light coat of new oil to the rubber gasket of the new filter.
Install the new oil filter and tighten it securely.
Refill the engine with the recommended grade and type of oil.

5. Test for Leaks

Start the engine and let it idle for a few minutes.
Check for any signs of oil leaks around the replaced gaskets and oil filter.
Monitor the oil level and ensure it remains stable.
