Install New Filter: Screw in the new filter by hand until snug, then tighten according to specifications.

4. Replace Gaskets or Seals

Drain Oil: Drain the engine oil using a wrench on the oil pan drain plug.
Remove Component: Take off the valve cover or oil pan as needed.
Clean Surface: Clean the mating surfaces of the engine and the components thoroughly to ensure a good seal.
Install New Gasket/Seal: Place a new gasket or seal in position; reassemble the component and torque it to specifications.

5. Refill Oil

Add Oil: Refill the engine with fresh oil through the oil filler cap according to the manufacturer's specifications.
Check Level: Use the dipstick to ensure the oil level is correct after filling.
