Solution

1. Preparation

Tools Required: Oil catch pan, rags, UV dye (optional), UV light (optional), engine oil, socket set.
Ensure the vehicle is on a level surface and the engine is cool.
Disconnect the battery (if working near electrical components).

2. Lift the Vehicle

Use a jack to lift the front of the vehicle and secure it with jack stands for safety.
Place an oil catch pan under the engine to collect any oil that may leak during inspection.

3. Inspect and Clean

Clean the engine components with a degreaser to remove any existing oil residue for better visibility.
Inspect the oil filter and replace it if it shows signs of leakage.
Check the oil pan and valve cover gaskets for cracks or wear; replace if necessary.

4. Repair Leaks

Oil Filter Replacement:
1. Remove the old oil filter using an oil filter wrench.
2. Lubricate the rubber gasket on the new filter with a bit of new oil.
3. Install the new filter and tighten it according to specifications.
Gasket Replacement:
1. Remove the components blocking access to the leaking gasket (if applicable).
2. Remove the old gasket material using a scraper.
3. Apply a new gasket or gasket maker as per manufacturer's recommendations.
4. Reassemble the components and tighten bolts to the manufacturer’s torque specifications.

5. Refill Oil

If oil has leaked out, refill the engine oil to the proper level using the recommended oil type.
