- Install the new oil filter and tighten it according to the manufacturer's specifications (typically hand-tight).
Valve Cover Gasket Replacement:
- Remove any components blocking access to the valve cover (if necessary).
- Unbolt the valve cover using a socket set (torque bolts to manufacturer specifications).
- Remove the old gasket and clean the mating surfaces.
- Install the new gasket and reassemble the valve cover.
Oil Pan Gasket Replacement:
- Drain the engine oil using an oil pan to collect used oil.
- Remove the oil pan bolts and the oil pan itself.
- Clean the old gasket material from the oil pan and engine surface.
- Install the new gasket and reinstall the oil pan, tightening bolts to the specified torque.

4. Refill Engine Oil

Replace the drained engine oil with the recommended type and amount as per the owner's manual.
Start the engine and let it run for a few minutes, checking for leaks around the repaired areas.
