Solution

1. Preparation

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

2. Identify the Leak Source

• Sub-step 1: Clean the area around the suspected leak source with a degreaser to remove old oil residue.
• Sub-step 2: Use a UV flashlight if dye was added to the oil to identify the exact leak location.

3. Repair or Replace Affected Components

• If the drain plug is leaking:

  • Sub-step 1: Use a socket wrench to remove the drain plug.
  • Sub-step 2: Inspect the washer or gasket for damage and replace if necessary.
  • Sub-step 3: Reinstall the drain plug and tighten to the specified torque.

• If gaskets or seals are leaking:

  • Sub-step 1: Remove components blocking access to the gasket (e.g., intake manifold, valve cover).
  • Sub-step 2: Remove the old gasket and clean the mating surfaces with a gasket scraper.
  • Sub-step 3: Apply a new gasket or sealant as per specifications and reassemble components.

4. Refill Oil
