Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the engine is cool and disconnect the battery to avoid electrical issues.

2. Identify Leak Source

If the leak is from a gasket or seal, proceed to replace the affected component.
For leaks from the oil pan, proceed to remove it for inspection.

3. Replace Gaskets/Seals

Sub-steps:
- Remove any components obstructing access to the gasket (intake manifold, exhaust components if necessary).
- Remove the old gasket or seal using a scraper and clean the surface with solvent.
- Apply a new gasket or sealant as per manufacturer specifications.
- Reassemble the components removed, ensuring proper torque specifications are followed.

4. Replace Oil Filter or Oil Pan (if applicable)

Sub-steps:
- For oil filter leaks, remove the old filter with an oil filter wrench, lubricate the O-ring of the new filter, and install it.
- If replacing the oil pan, drain the oil completely, unbolt the oil pan, clean the mating surfaces, and install the new oil pan with a new gasket.
- Torque the bolts to manufacturer specifications.

5. Refill Engine Oil

Use the recommended type and amount of engine oil.
Start the engine and allow it to run for a few minutes, checking for leaks.
