Solution

1. Preparation

Gather tools and parts required for the repair.
Tools Required:
- Socket set
- Screwdrivers
- Oil catch pan
- Torque wrench
- O-ring pick (if needed)
- OBD-II scanner
Raise the vehicle using a jack and secure it with jack stands.

2. Locate the Source of the Leak

Clean the engine area with a degreaser to remove old oil and debris.
Start the engine and run it at idle while observing the previously cleaned areas to identify the source of the leak.

3. Repair the Leak

If the oil filter is leaking:
- Remove the old oil filter using an oil filter wrench.
- Ensure the rubber O-ring from the old filter is removed.
- Install a new oil filter, tightening it by hand until it's snug (do not over-tighten).
If the oil pan is leaking:
- Drain the oil using the oil catch pan.
- Remove the oil pan bolts and gently tap the pan to remove it.
- Clean the mating surfaces and apply a new gasket or RTV sealant as per manufacturer specifications.
- Reinstall the oil pan, tightening bolts to the manufacturer's torque specifications.
If gaskets or seals are leaking:
- Remove the components covering the affected gaskets (e.g., valve cover).
- Clean the surfaces and replace the worn gaskets with new ones.
- Reassemble and torque the bolts to the specified settings.

4. Refill Oil and Test

Refill the engine with the appropriate type and amount of oil as specified in the owner's manual.
Start the engine and check for any signs of leaks around the repaired areas.
