Solution

1. Preparation

Tools Required: Socket set, wrench set, oil catch pan, rags, OBD-II scanner.
Allow the engine to cool completely before starting work to avoid burns.

2. Identify and Fix Oil Leaks

Locate the Leak:
- Clean the engine bay with degreaser to remove old oil residue for better visibility.
- Start the engine and observe for any new oil leaks during idle and as the engine warms up.
Replace Gaskets or Seals:
- If leaks are identified at the valve cover gaskets:
  - Remove the bolts securing the valve cover using a socket wrench.
  - Carefully lift the valve cover off, ensuring the old gasket comes off with it.
  - Clean the mating surface on the engine and the valve cover.
  - Install a new gasket and reattach the valve cover, torquing bolts to the manufacturer’s specifications (usually around 89-130 in-lbs).
- For oil pan leaks:
  - Drain the engine oil into an oil catch pan.
  - Remove the oil pan bolts and gently tap the oil pan to break the seal.
  - Clean the surface and install a new gasket or use RTV silicone sealant as per service manual.
  - Reinstall the oil pan, torquing bolts to specifications.

3. Replace Oil Filter (if necessary)

If the oil filter is found to be leaking:
- Remove the old oil filter using an oil filter wrench.
- Apply a small amount of clean oil to the rubber gasket of the new filter.
- Install the new oil filter and tighten it according to manufacturer specifications.

4. Refill Engine Oil

Refill the engine with manufacturer-recommended oil type and quantity.
Start the engine and check for any leaks around the repaired areas.
