- Lubricate the rubber gasket on the new filter with a bit of engine oil.
- Install the new oil filter and tighten it according to specifications (typically hand-tight plus a quarter turn).
Drain Plug Replacement
- If the drain plug is leaking, remove it using a socket wrench.
- Inspect the O-ring for damage; replace if necessary.
- Reinstall the drain plug and torque it to the manufacturer’s specifications.
Valve Cover Gasket Replacement
- Remove any components obstructing access (e.g., ignition coils).
- Unscrew the valve cover bolts and carefully lift the cover off.
- Remove the old gasket and clean the mating surfaces.
- Install a new gasket and reassemble the valve cover, tightening bolts to the specified torque.
