Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal for safety if performing electrical work.

2. Identify the Source of the Leak

Sub-steps:
1. Clean the engine area with engine degreaser to remove old oil residue.
2. Start the engine and let it run for a few minutes.
3. Observe the engine for new oil seeping out from potential leak points (oil filter, oil pan, valve cover).

3. Replace Gaskets and Seals

Sub-steps:
1. If the valve cover gasket is leaking, remove the valve cover by loosening the bolts (torque specification: 7.5 lb-ft).
2. Remove the old gasket and clean the mating surfaces.
3. Install a new valve cover gasket ensuring proper alignment.
4. Reinstall the valve cover and torque the bolts to specification.
If the oil pan gasket is leaking:
1. Drain the engine oil using an oil pan.
2. Remove the oil pan by loosening the bolts (torque specification: 12 lb-ft).
3. Replace the old gasket, clean the surfaces, and reinstall the oil pan.
4. Refill the engine with the correct type of oil (5W-20).

4. Replace Oil Filter

Sub-steps:
1. Locate the oil filter and use an oil filter wrench to remove it.
2. Apply a small amount of new oil to the rubber gasket of the new oil filter.
3. Install the new oil filter and tighten it according to the manufacturer’s specifications.

5. Final Check

Sub-steps:
1. Reconnect the negative battery terminal if it was disconnected.
2. Start the engine and let it run for a few minutes.
3. Check for any new oil leaks around the replaced components.
4. Monitor the oil level and top up if necessary.
