Solution

1. Preparation

Ensure the vehicle is parked on a level surface.
Gather necessary tools and parts.
Disconnect the negative terminal of the battery to prevent electrical issues.

2. Inspect and Repair Oil Leaks

Tools Required: Socket set, torque wrench, gasket scraper
Inspect the oil pan, valve covers, and gaskets for leaks.
If leaks are found:
1. Remove the affected component (e.g., oil pan or valve cover).
2. Clean the gasket surfaces using a gasket scraper.
3. Replace gaskets or seals as necessary.
4. Reinstall the component and torque to manufacturer specifications.

3. Investigate Engine Components (If applicable)

Tools Required: Compression tester, leak-down tester
Perform a compression test to check for internal engine issues.
If low compression is detected, conduct a leak-down test to identify the source of the problem.
Based on findings, consider further disassembly of the engine components or replacing faulty parts (e.g., piston rings).

4. Replace Oil and Filter

Tools Required: Oil filter wrench, oil catch pan, funnel
Drain the old oil using an oil catch pan.
Replace the oil filter with a new one.
Refill the engine with the manufacturer-recommended oil type and quantity.
