Solution

1. Preparation

Gather tools and parts. Ensure the vehicle is parked on a level surface.
Disconnect the battery to prevent any electrical issues during inspection.

2. Inspect for Leaks

Tools Required: Socket set, flashlight, rags
Inspect the oil pan seal and all gaskets (valve cover, oil filter) for signs of wear or leaks.
Clean any oil residue and monitor for fresh leaks after running the engine for a short period.

3. Replace Faulty Components

Tools Required: Torque wrench, replacement gaskets/seals
If any leaks are found, replace the damaged gaskets or seals as needed.
Torque all bolts to the manufacturer specifications to ensure a proper seal.

4. Check and Replace PCV Valve

Tools Required: Pliers, replacement PCV valve
Locate the PCV valve, remove it from the valve cover, and inspect it for clogs.
Replace with a new PCV valve if it is blocked or not functioning properly.

5. Perform Compression Test

Tools Required: Compression tester
Remove spark plugs and connect the compression tester to each cylinder.
Record values; a significant drop in compression indicates potential internal engine wear.

6. Clean the Intake System

Tools Required: Intake cleaner, cleaning cloths
Remove the intake manifold if oil is found in the intake system.
Clean the intake ports and manifold thoroughly before reassembling.
