2. Inspect and Tighten Components

Tools Required: Socket set
Check the oil drain plug:
- Loosen and remove the drain plug with a socket wrench.
- Inspect the gasket for damage; replace if necessary.
- Reinstall and torque the drain plug to the manufacturer’s specification (typically around 20-25 lb-ft).

3. Replace the Oil Filter

Tools Required: Oil filter wrench
Remove the oil filter:
- Use an oil filter wrench to carefully unscrew the old filter.
- Ensure the rubber O-ring from the old filter is removed from the mounting surface.
Install a new oil filter:
- Apply a thin layer of clean oil to the new filter's O-ring.
- Screw on the new filter until snug, then tighten an additional ¾ turn.

4. Replace Gaskets if Necessary

Tools Required: Torque wrench, gasket scraper
For the valve cover gasket:
- Remove the valve cover by loosening the bolts using a socket set.
- Lift the cover and remove the old gasket, cleaning any residue from the surfaces.
- Place a new gasket on the valve cover and reinstall, torquing the bolts to manufacturer specifications (typically around 7-9 lb-ft).
For the oil pan gasket:
- Drain the oil completely and remove the oil pan by loosening its bolts.
- Clean the mating surfaces thoroughly and replace the gasket.
- Reinstall the oil pan, torquing the bolts to the manufacturer’s specifications (usually around 10-15 lb-ft).
