Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface, and the engine is cool.
Disconnect the battery to avoid electrical issues.

Tools Required:

Socket set
Torque wrench
Oil catch pan
Clean rags
Screwdriver set
O-ring pick (if needed)

2. Identify the Leak Source

Clean the engine area with engine degreaser to remove old oil residue.
Start the engine and let it run for a few minutes to observe where fresh oil is leaking from.
Turn off the engine and mark the leak's location.

3. Replace Gaskets or Seals

If the leak is from the valve cover gaskets:
- Remove the engine cover if present.
- Unbolt the valve cover and carefully lift it off.
- Remove the old gaskets and clean the mating surfaces.
- Install new gaskets and reassemble.
- Torque the bolts to the manufacturer's specifications (typically around 89 in-lbs).
If the leak is from the oil pan:
- Drain the engine oil using the oil catch pan.
- Remove the oil drain plug and let the oil completely drain.
- Unbolt the oil pan, taking care not to damage the pan.
- Remove the old gasket and clean the pan and engine surface.
- Install a new gasket and reassemble the oil pan, torquing bolts to specifications (usually around 106 in-lbs).

4. Replace the Oil Filter

Remove the old oil filter using an oil filter wrench.
Apply a small amount of oil to the rubber O-ring of the new filter.
Install the new oil filter, ensuring it is snug, but do not overtighten.

5. Refill Engine Oil

Replace the oil drain plug securely.
Refill the engine with fresh oil as specified in the owner's manual (typically 5W-20 for this model).
Start the engine and let it run for a few minutes, then check the oil level and add more if necessary.
