Solution

1. Preparation

Gather tools and parts necessary for the repair.
Park the vehicle on a level surface and engage the parking brake.
Allow the engine to cool completely before proceeding.
Disconnect the negative battery cable for safety.

2. Inspect and Replace Oil Filter

Tools Required: Oil filter wrench, oil catch pan.
Remove the old oil filter using the oil filter wrench.
Clean the mounting surface on the engine.
Apply a thin layer of new oil on the gasket of the new filter.
Install the new oil filter by hand, and tighten according to the manufacturer’s specifications (usually hand-tight plus 3/4 turn).

3. Inspect and Replace Valve Cover Gaskets

Tools Required: Socket set, torque wrench, gasket scraper, RTV silicone (if required).
Remove any engine covers that obstruct access to the valve covers.
Unbolt the valve covers carefully, noting the sequence for reinstallation.
Remove the old gaskets and clean the surfaces thoroughly.
Place new gaskets onto the valve covers and apply RTV silicone in areas as specified by manufacturer guidelines.
Reinstall the valve covers and torque the bolts to the specified torque value.

4. Inspect and Tighten Oil Drain Plug

Tools Required: Socket set.
Place an oil catch pan underneath the oil drain plug.
Inspect the drain plug for damage or wear; replace it if necessary.
Tighten the drain plug to the manufacturer’s torque specification.
