Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Allow the engine to cool before starting work.

2. Inspect for External Leaks

Sub-steps:
- Visually inspect the oil pan, valve covers, and seals for any signs of oil leakage.
- Clean any accumulated oil with a degreaser to identify the source of leaks.
Tools Required:
- Mechanic's mirror
- Degreaser
Safety Warnings:
- Ensure the engine is cool before touching components.

3. Perform Compression Test

Sub-steps:
- Remove spark plugs and connect a compression gauge to each cylinder.
- Crank the engine and record compression readings for each cylinder.
- Compare readings against manufacturer specifications.
Tools Required:
- Compression gauge
Safety Warnings:
- Disconnect the ignition coil to prevent the engine from starting during the test.

4. Check PCV System

Sub-steps:
- Locate the PCV valve and remove it for inspection.
- Clean or replace the PCV valve if clogged or damaged.
