Solution

1. Preparation

Gather necessary tools and parts.
Ensure the engine is cool and disconnect the battery.
Raise the vehicle using a jack and secure it with jack stands.

2. Identify the Leak Source

If the leak is from the oil filter:
1. Use an oil filter wrench to remove the old oil filter.
2. Inspect the sealing surface on the engine for debris or old gasket material.
3. Lubricate the rubber O-ring of the new oil filter with clean oil and install it, tightening it to manufacturer specifications.
If the leak is from the oil pan:
1. Drain the engine oil by removing the oil drain plug with a socket wrench.
2. Remove the oil pan bolts and gently pry the oil pan off.
3. Clean the mating surfaces thoroughly and replace the oil pan gasket.
4. Reinstall the oil pan, ensuring to torque the bolts to the specified value.
If the leak is from the valve cover:
1. Remove any components obstructing access to the valve cover (e.g., air intake).
2. Unscrew the valve cover bolts and gently lift the valve cover off.
3. Clean the surfaces and replace the valve cover gasket.
4. Reinstall the valve cover and torque the bolts to specifications.

3. Refill Engine Oil

Replace the oil drain plug and refill the engine with the correct type and amount of oil as specified in the owner's manual.
