  2. Unbolt the valve cover using a socket set.
  3. Remove the old gasket and clean the mating surfaces.
  4. Place the new gasket in position and reinstall the valve cover.
  5. Torque the bolts to the manufacturer's specifications (usually around 10-12 Nm).
- Oil Pan Gasket Replacement:
  1. Drain the engine oil using an oil catch pan.
  2. Remove the oil pan bolts and gently pry the oil pan loose.
  3. Clean the surface and remove the old gasket.
  4. Install the new gasket and reattach the oil pan, torquing the bolts to specification (typically 20-25 Nm).

4. Replace Oil Filter (if necessary)

If the oil filter is leaking or damaged:
1. Remove the oil filter using an oil filter wrench.
2. Lubricate the rubber O-ring on the new oil filter with fresh oil.
3. Install the new oil filter and tighten it according to specifications (usually hand-tight plus 3/4 turn).
