Solution

1. Preparation

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

2. Locate the Leak Source

Clean the oil-drenched area with a degreaser to clearly identify where the oil is leaking from.
If necessary, use UV dye in the oil to detect the leak more accurately.

3. Replace Gaskets and Seals

Oil Pan Gasket Replacement:
- Drain the engine oil using an oil drain pan.
- Remove the oil pan bolts using a socket set.
- Carefully pry the oil pan off and remove the old gasket.
- Clean the oil pan surface and apply a new gasket.
- Reinstall the oil pan and torque bolts to the manufacturer’s specifications (typically around 10-15 ft-lbs).
Replace Valve Cover Gasket (if needed):
- Remove the ignition coils and spark plugs to access the valve cover.
- Unscrew the valve cover bolts and remove the valve cover.
- Replace the old gasket with a new one and reassemble.

4. Inspect and Replace the Oil Filter

Use an oil filter wrench to remove the old oil filter.
Apply a small amount of oil to the rubber gasket of the new oil filter.
Install the new oil filter, ensuring it is snug but not overly tight.

5. Refill Engine Oil

Refill the engine with the appropriate type and amount of oil (check owner’s manual for specifications).
Start the engine and let it run for a few minutes while checking for leaks.
