Solution

1. Preparation

Gather necessary tools and parts.
Ensure the engine is cool and the vehicle is parked on a flat surface.
Disconnect the battery to prevent electrical issues.

2. Addressing Oil Leaks

Inspect and Replace Gaskets:
1. Remove engine covers if necessary to access valve cover and oil pan gaskets.
2. Use a socket set to remove bolts securing the valve cover or oil pan.
3. Carefully lift the cover/pan and inspect the old gasket.
4. Clean the surface of the engine and the cover/pan with a gasket scraper and solvent.
5. Apply a new gasket or gasket sealant as per manufacturer specifications.
6. Reinstall the cover/pan and torque bolts to manufacturer specifications.
Check Oil Filter:
1. Inspect the oil filter for proper tightness using an oil filter wrench.
2. If leaking, replace the oil filter with a new, compatible unit.
3. Lubricate the new filter's rubber O-ring with a small amount of oil before installation.

3. Refill Engine Oil

If the oil level was low, refill it with the appropriate type and grade of oil as specified in the owner’s manual.
Start the engine and allow it to run for a few minutes, checking for leaks.

4. Final Inspection

Inspect the engine bay for any signs of fresh oil leaks after the engine has run.
Ensure no smoke or burning smell is present.
