Safety Warnings: Ensure the engine is cool before starting work to avoid burns. Disconnect the battery if necessary.

2. Locate the Leak Source

Sub-steps:
1. Inspect the Oil Filter: Ensure it is tightened properly and check for signs of oil seeping from the gasket.
2. Examine the Oil Pan Gasket: Look for cracks or damage; if found, prepare to replace it.
3. Check Valve Cover Gasket: Inspect for leaks around the edges; if oil is present, it may need replacement.
4. Inspect Seals: Examine front and rear main seals for any oil seepage.

3. Repairing the Leak

Sub-steps:
1. Replace Oil Filter (if leaking):
  - Remove the old filter using an oil filter wrench.
  - Apply a thin layer of clean oil to the gasket of the new filter.
  - Install the new filter and tighten it according to manufacturer specifications.
2. Replace Oil Pan Gasket (if leaking):
  - Drain engine oil into an oil catch pan.
  - Remove bolts securing the oil pan and gently pry it off.
  - Clean the mating surfaces and install a new gasket.
  - Reattach the oil pan and torque bolts to the manufacturer's specifications.
3. Replace Valve Cover Gasket (if leaking):
  - Remove any components obstructing access to the valve cover.
  - Unscrew the valve cover and remove the old gasket.
  - Clean the surfaces and place a new gasket, then reassemble and torque to specifications.
