Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is on a level surface and the engine is cool.
Disconnect the battery to avoid any electrical issues.

2. Drain Engine Oil

Place an oil catch pan under the oil pan.
Remove the oil drain plug using a socket wrench and allow the oil to fully drain into the pan.
Replace the drain plug and torque to manufacturer's specifications (typically 20-25 ft-lbs).

3. Replace Gaskets/Seals

A. Oil Pan Gasket

Remove any fasteners securing the oil pan using a socket set.
Carefully pry the oil pan from the engine block, ensuring not to damage the mating surfaces.
Remove the old gasket and clean the mating surfaces with a gasket scraper.
Apply a new gasket or RTV sealant as specified by the manufacturer.
Reinstall the oil pan and torque the bolts to the specified value.

B. Valve Cover Gasket

Remove any components obstructing access to the valve cover (such as ignition coils).
Unscrew the valve cover bolts and gently lift the cover off.
Replace the old gasket with a new one and clean the mating surfaces.
Reinstall the valve cover and torque the bolts to the specified value.

C. Crankshaft Seals

If leaking, remove the components necessary to access the front and/or rear crankshaft seals (timing belt/chain, flexplate).
Use a seal puller to remove the old seals.
Lubricate and install the new seals carefully, ensuring they are seated properly.
Reassemble all components removed in reverse order.
