Oil Pan Gasket Replacement:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Place a drain pan under the oil pan.
3. Remove the drain plug and let the engine oil drain completely.
4. Remove the bolts securing the oil pan.
5. Gently pry the oil pan loose and remove it.
Valve Cover Gasket Replacement:
1. Remove any components that obstruct access to the valve cover (e.g., intake manifold or ignition coils).
2. Unscrew the valve cover bolts and carefully lift off the cover.
3. Remove the old gasket material from both the cover and the engine.
Oil Filter Replacement:
1. Use an oil filter wrench to remove the old oil filter.
2. Apply a little new oil to the rubber seal of the new filter.
3. Install the new oil filter and tighten it to the manufacturer's specifications.

3. Install New Gaskets

Clean the surfaces thoroughly to ensure a proper seal.
Place the new gasket on the oil pan or valve cover, aligning it with the bolt holes.
Reinstall the oil pan or valve cover, tightening the bolts to the specified torque in a crisscross pattern.

4. Refill Engine Oil

Replace the drain plug and refill the engine with the appropriate type and amount of oil as specified in the owner's manual.
Reconnect the negative battery terminal.
