Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a flat surface, engage the parking brake, and allow the engine to cool.

Tools Required:

Socket set
Torque wrench
Oil filter wrench
Clean rags
Oil drain pan
OBD-II scanner (optional)

2. Drain Engine Oil

Position the oil drain pan under the oil pan.
Remove the oil drain plug using the appropriate socket.
Allow the oil to fully drain into the pan.
Replace the drain plug and torque to the manufacturer's specifications (typically around 25 Nm or 18 lb-ft).

3. Replace Oil Filter

Use the oil filter wrench to remove the old oil filter.
Clean the mounting surface on the engine.
Apply a thin layer of new oil to the rubber gasket on the new oil filter.
Install the new oil filter by hand until snug, then tighten it according to the manufacturer's specifications (usually 3/4 turn after the gasket makes contact).

4. Repair Leaking Seals and Gaskets

Identify the leaking seal or gasket (e.g., valve cover gasket).
Remove any components obstructing access to the gasket or seal.
Remove the old gasket or seal using a scraper if necessary.
Clean the mating surfaces thoroughly with a suitable solvent.
Install the new gasket or seal, ensuring proper alignment.
Reassemble any components that were removed, torquing bolts to the specified values.

5. Refill Engine Oil

Open the engine oil filler cap.
Using a funnel, pour in the new engine oil (refer to the owner's manual for the correct type and amount).
Replace the oil filler cap securely.
