Drain the engine oil by removing the oil drain plug.
Remove any bolts securing the oil pan to the engine block.
Carefully pry off the oil pan and remove the old gasket material.
Clean the mating surfaces thoroughly.
Install a new gasket and torque the oil pan bolts to the manufacturer's specifications (typically around 8-15 ft-lbs, but check the service manual).

4. Address Valve Cover Gasket

Tools Required: Socket set, torque wrench
Remove the bolts securing the valve cover.
Lift the valve cover off and remove the old gasket.
Clean both surfaces and install a new gasket.
Reinstall the valve cover and torque bolts to the specified value (typically around 7-10 ft-lbs).

5. Check and Replace Seals

Tools Required: Seal puller, socket set, torque wrench
Inspect the front and rear main seals for leaks.
If seals are leaking, remove the crankshaft pulley (front seal) or the transmission (rear seal).
Replace the seals with new ones, ensuring they are seated correctly.
Reassemble components and torque to manufacturer specifications.
