Solution

Solution

1. Preparation

  • Gather necessary tools and parts.
  • Park the vehicle on a level surface and allow the engine to cool.
  • Disconnect the negative battery cable for safety.

2. Identify and Remove the Leaking Component

  • Oil Pan Gasket Replacement:

    • Drain the engine oil using an oil pan and socket set.
    • Remove the oil drain plug and allow the oil to fully drain.
    • Remove the oil pan bolts and gently pry the oil pan free.
    • Clean the oil pan surface and the engine block with a scraper to remove old gasket material.

  • Valve Cover Gasket Replacement:

    • Remove necessary components obstructing access to the valve cover (e.g., intake manifold).
