Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the engine is cool and the vehicle is parked on a level surface.
Disconnect the battery to prevent any electrical issues.

2. Identify the Source of the Leak

Sub-step 1: Clean the engine surface with a degreaser to remove existing oil residue.
Sub-step 2: Run the engine for a few minutes and observe for new oil leaks.
Sub-step 3: If using UV dye, add it to the oil and run the engine for a short period. Use a UV light to pinpoint the leak.

3. Replace Faulty Components

Sub-step 1: If the oil filter is leaking, remove it using an oil filter wrench and replace it with a new one, ensuring to lubricate the rubber seal.
Sub-step 2: If the valve cover gasket is leaking, remove the valve cover by unbolting it (follow torque specifications for reinstallation). Clean the mating surfaces and replace the gasket.
Sub-step 3: If the oil pan is damaged, drain the oil, remove the oil pan by unbolting it, clean the surface, and replace the gasket or pan as necessary before reassembling.

4. Refill Oil

Sub-step 1: After completing repairs, refill the engine with the correct type and amount of oil as specified in the owner's manual.

5. Test for Leaks

Sub-step 1: Start the engine and allow it to idle. Observe the repaired areas for any signs of leakage.
Sub-step 2: Take the vehicle for a short test drive and check for oil leaks again.
