Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal for safety.

2. Inspect and Replace Gaskets/Seals

A. Valve Cover Gasket

Remove any engine covers as necessary.
Unscrew the valve cover bolts using a socket set.
Carefully lift the valve cover off and remove the old gasket.
Clean the mating surfaces on both the valve cover and engine block.
Place the new gasket onto the valve cover.
Reinstall the valve cover and tighten bolts to the manufacturer's torque specifications (typically around 10-15 ft-lbs).

B. Oil Pan Gasket

Drain the engine oil using an oil pan and wrench to remove the drain plug.
Remove the bolts holding the oil pan in place.
Carefully pry the oil pan free and remove the old gasket.
Clean the oil pan and engine block surfaces thoroughly.
Install the new gasket on the oil pan.
Reinstall the oil pan and tighten the bolts to manufacturer specifications.
Replace the drain plug and refill with new engine oil.

C. Oil Filter

Locate the oil filter and use an oil filter wrench to remove it.
Apply a small amount of new oil to the rubber O-ring on the new oil filter.
Install the new oil filter and hand-tighten it securely.

3. Final Checks

Reconnect the negative battery terminal.
Start the engine and let it idle briefly while checking for leaks.
Turn off the engine and check the oil level with the dipstick, adding oil if necessary.
