- Remove the old oil filter using the oil filter wrench.
- Apply a thin layer of new oil to the rubber gasket of the new filter.
- Install the new filter and tighten it to the specified torque of 25 Nm (18 lb-ft).
Gasket Replacement:
- For any damaged gaskets (e.g., valve cover, oil pan), remove the affected component.
- Clean the mating surfaces thoroughly.
- Install the new gasket and secure the component with bolts, tightening them to the manufacturer’s torque specifications.

4. Refill Oil

After repairs, refill the engine with the appropriate type and amount of oil (check owner’s manual for specifications).
Start the engine and let it idle for a few minutes to circulate the oil.
