1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery if working on electrical components near the engine.

2. Inspect and Replace Oil Filter

Tools Required: Oil filter wrench, drain pan
Remove the oil drain plug and allow the old oil to drain into the pan.
- Torque the drain plug to manufacturer specifications (typically 20-25 ft-lbs).
Remove the old oil filter using the oil filter wrench.
Apply a thin layer of new oil to the rubber gasket of the new filter.
Install the new oil filter by hand until snug, then tighten an additional 3/4 turn.

3. Replace Valve Cover Gasket

Tools Required: Socket set, torque wrench, gasket scraper
Remove the bolts securing the valve cover using the socket set.
Lift off the valve cover and remove the old gasket.
Clean the mating surfaces with a gasket scraper.
Install the new gasket onto the valve cover.
Reinstall the valve cover and tighten bolts to the specified torque (usually 7-10 ft-lbs).

4. Replace Oil Pan Gasket

Tools Required: Socket set, torque wrench, gasket scraper
Drain the oil again if necessary.
Remove the oil pan bolts using the socket set.
Carefully lift the oil pan off, ensuring no debris falls into the engine.
Remove the old gasket and clean the mating surface.
Install the new gasket and reattach the oil pan.
