Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical issues.

2. Inspect and Replace Gaskets/Seals

Inspect the valve cover gasket:
- Remove any engine covers obstructing access.
- Unbolt the valve cover using a socket set.
- Carefully lift the valve cover and inspect the gasket for wear or damage.
Replace the gasket:
- Clean the mating surfaces with a gasket scraper and solvent.
- Apply a thin layer of gasket sealant, if required, and position the new gasket.
- Reinstall the valve cover and torque to manufacturer's specifications (typically around 10-12 Nm).

3. Address Oil Filter and Drain Plug

Inspect and replace the oil filter:
- Use an oil filter wrench to remove the old oil filter.
- Lubricate the O-ring of the new oil filter with fresh oil and install it, tightening according to specifications.
Check and tighten drain plug:
- Inspect the oil drain plug for wear; replace if damaged.
- Tighten the drain plug to the recommended torque (usually around 25 Nm).

4. Clean and Reassemble

Wipe down any spilled oil and surrounding components to prevent smoke and odors.
Reinstall any engine covers removed during the inspection.
Reconnect the battery.
