1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical issues.

Oil Filter:
- Remove the old oil filter using an oil filter wrench.
- Apply a thin layer of new oil to the rubber gasket of the new filter.
- Install the new oil filter, tightening it by hand until secure.
Oil Drain Plug:
- Place an oil catch pan under the oil drain plug.
- Remove the drain plug using a socket wrench, allowing oil to drain completely.
- Inspect the crush washer; replace if damaged.
- Reinstall the drain plug and torque to manufacturer specifications (typically around 25-30 ft-lbs).
Gaskets and Seals:
- Remove the affected components (e.g., valve cover, oil pan) as necessary.
- Clean the mating surfaces thoroughly to remove old gasket material.
- Apply a new gasket or RTV sealant as per manufacturer specifications.
- Reinstall the components and torque bolts to specified values.

3. Refill Engine Oil

Ensure all repairs are complete and components are securely fastened.
Refill the engine with the appropriate type and amount of oil (check the owner’s manual for specifications).
