Solution

1. Preparation

Gather necessary tools and parts.
Ensure the engine is cool and the vehicle is parked on a level surface.
Disconnect the negative battery terminal to ensure safety.

2. Addressing Oil Leaks

A. Inspect and Replace Valve Cover Gasket

Remove any covers or components obstructing access to the valve cover.
Unbolt the valve cover using a socket set.
Gently lift the valve cover off and inspect the gasket for wear or damage.
Clean the mating surfaces with a gasket scraper and solvent.
Install a new valve cover gasket, ensuring proper alignment.
Reinstall the valve cover and torque bolts to the manufacturer's specifications (typically around 7-9 ft-lbs).

B. Check and Tighten Oil Drain Plug

Place an oil catch pan under the oil pan.
Use a socket wrench to check the tightness of the oil drain plug.
If loose, tighten it to the manufacturer's torque specifications (usually around 20-25 ft-lbs).

C. Replace Oil Filter

Locate the oil filter and place an oil catch pan underneath.
Use an oil filter wrench to remove the old filter.
Apply a small amount of new oil to the rubber gasket of the new filter.
Install the new oil filter and tighten according to the manufacturer's recommendations (generally hand-tight).

3. Refill Engine Oil

If oil was lost, refill with the appropriate type and amount of oil (consult the owner's manual for specifications).
Check the oil level with the dipstick and ensure it is within the recommended range.
