Solution

1. Preparation

Gather tools and materials: Oil catch pan, socket set, torque wrench, UV dye kit, blacklight, and replacement gaskets if necessary.
Park the vehicle on a level surface and allow the engine to cool before starting work.

2. Identify Leak Source

Clean the engine area with degreaser to remove old oil and grime.
Use the UV dye kit: Add UV dye to the engine oil and run the engine for a few minutes.
Shine the blacklight around suspected leak areas to identify the exact source of the leak.

3. Repair the Leak

If the leak is from the oil filter:

Remove the old oil filter using an oil filter wrench.
Apply a thin layer of oil to the rubber gasket of the new filter.
Install the new filter by hand, then tighten it according to the manufacturer's specifications (typically 3/4 turn after the rubber gasket makes contact).

If the leak is from the oil pan:

Drain the engine oil using an oil catch pan.
Remove the oil pan bolts and gently pry the oil pan off.
Replace the oil pan gasket with a new one, ensuring it is aligned properly.
Reinstall the oil pan and torque the bolts to the manufacturer's specifications (consult the service manual for specific torque values).
Refill the engine with the appropriate oil type and quantity.

If the leak is from gaskets or seals:

Replace any compromised gaskets (valve cover, crankshaft seals) using proper tools and torque specifications.
Ensure all surfaces are clean and free of old gasket material before installation.
