Ensure the vehicle is parked on a level surface and the engine is cool.

2. Identify and Replace Faulty Components

Oil Filter Replacement
1. Use the oil filter wrench to remove the old oil filter.
2. Apply a small amount of new oil to the rubber gasket of the new filter.
3. Install the new oil filter, ensuring it is snug but not over-tightened (generally hand-tight is sufficient).
Valve Cover Gasket Replacement
1. Remove any accessories or components obstructing access to the valve cover (if necessary).
2. Unbolt the valve cover using the socket set, noting the order and location of bolts for reassembly.
3. Remove the old gasket and clean the mating surfaces thoroughly.
4. Place the new gasket onto the valve cover, ensuring it is seated properly.
5. Reinstall the valve cover and torque the bolts to the manufacturer’s specifications (typically around 8-10 Nm).
Oil Pan Gasket Replacement (if applicable)
1. Drain the engine oil completely using a drain pan.
2. Remove the oil pan by unbolting it carefully and prying it off if it is stuck.
3. Clean the mating surfaces of the oil pan and engine block.
4. Install the new gasket and reattach the oil pan, torquing the bolts as specified (usually around 10-12 Nm).
5. Refill the engine with the appropriate type and amount of oil.

3. Clean Up

Wipe any spilled oil from the engine and surrounding components.
Dispose of old oil and oil filters properly according to local regulations.
