Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is on a level surface and securely supported.
Disconnect the negative battery terminal for safety.

2. Inspect and Repair Leaks

Sub-steps:
1. Clean the engine surface with a degreaser.
2. Inspect the oil pan, valve cover, and front and rear main seals for leaks.
3. Replace any faulty gaskets or seals with new ones.
Tools Required: Socket set, torque wrench, gasket scraper.
Safety Warnings: Allow engine to cool before working on it.

3. Replace Worn Components

Sub-steps:
1. If compression or leak-down tests indicate wear, consider replacing piston rings or valve seals.
2. Remove the cylinder head if necessary to access and replace valve seals.
3. Reassemble all components and ensure proper torque specifications are followed.
Tools Required: Torque wrench, socket set, ring compressor.
Safety Warnings: Follow safety procedures when handling engine components.
