Solution

1. Preparation

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

2. Visual Inspection

Use a flashlight to inspect the engine bay and undercarriage.
Look for oil residue on the engine components, undercarriage, and around the oil filter.

3. Tighten Loose Components

Use a socket set to check and tighten any loose oil filter or oil pan bolts.
Ensure that the valve cover bolts are also properly torqued.

4. Replace Gaskets and Seals

Oil Filter Gasket:
- Remove the oil filter using an oil filter wrench.
- Clean the mounting surface on the engine.
- Install a new oil filter, ensuring the rubber gasket is lubricated with fresh oil.
Valve Cover Gasket:
- Remove the valve cover bolts with a socket set.
- Carefully lift the valve cover off and remove the old gasket.
- Clean the mating surfaces and install a new gasket, ensuring proper alignment before reinstallation.
Oil Pan Gasket:
- Drain the engine oil using an oil drain pan.
- Remove the oil pan bolts and carefully detach the oil pan.
- Remove the old gasket, clean the surfaces, and install a new gasket before reattaching the oil pan.

5. Final Assembly

Refill the engine with the appropriate oil type and quantity.
Start the engine and let it run for a few minutes, then inspect for any leaks around the replaced components.
