Solution

1. Preparation

Gather necessary tools and parts before starting the repair.
Ensure the engine is cool and the vehicle is parked on a flat surface.
Disconnect the negative battery terminal to avoid electrical issues.

2. Identify and Replace the Faulty Component

A. Check the Oil Filter

Tools Required: Oil filter wrench, oil catch pan
Remove the oil filter using the wrench.
Inspect the rubber O-ring on the old filter for damage.
Install a new oil filter, ensuring the O-ring is lubricated and properly seated.

B. Inspect and Replace Gaskets

Tools Required: Socket set, torque wrench, gasket scraper
Remove any components obstructing access to the valve cover or oil pan (if necessary).
Use a socket set to remove the bolts securing the valve cover or oil pan.
Carefully lift off the cover/pan and remove the old gasket material using a scraper.
Clean the mating surfaces thoroughly.
Place a new gasket and reinstall the cover/pan, tightening bolts to the manufacturer’s specified torque values.

3. Refill Engine Oil

Tools Required: Funnel
After replacing the filter and gaskets, refill the engine with the recommended type and amount of oil.
Use a funnel to avoid spills and check the dipstick to ensure proper oil level.
