Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and allow the engine to cool.
Disconnect the battery for safety.

2. Inspect and Replace Gaskets and Seals

Tools Required: Socket set, torque wrench, gasket scraper, engine oil
Sub-steps:
1. Remove components obstructing access to the valve cover or oil pan.
2. Remove the valve cover or oil pan bolts using the socket set.
3. Carefully lift the cover/pan off and inspect for worn gaskets.
4. Clean the mating surfaces with a gasket scraper and solvent.
5. Install new gaskets and reassemble components, ensuring proper torque specifications are followed (consult the service manual for torque values).

3. Replace Oil Filter (if necessary)

Tools Required: Oil filter wrench, oil catch pan
Sub-steps:
1. Position the oil catch pan underneath the oil filter.
2. Use the oil filter wrench to remove the old oil filter.
3. Apply a thin layer of new oil to the rubber gasket of the new oil filter.
4. Install the new filter by hand until snug, then tighten slightly with the wrench.

4. Refill Engine Oil

Tools Required: Funnel
