Solution

1. Preparation

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

2. Address Oil Filter Issues

Tools Required: Oil filter wrench, new oil filter
Remove the old oil filter using the oil filter wrench.
Apply a thin layer of new oil to the rubber gasket of the new oil filter.
Install the new oil filter by hand, ensuring it is snug but not over-tightened.

3. Replace Faulty Gaskets or Seals

Tools Required: Socket set, torque wrench, gasket scraper
Identify the faulty gasket or seal (e.g., valve cover gasket or oil pan gasket).
Remove any engine covers or components obstructing access to the gasket.
Carefully remove the old gasket using a gasket scraper and clean the surface to ensure a proper seal.
Install the new gasket according to the manufacturer’s specifications, ensuring correct torque settings.

4. Tighten or Replace Oil Drain Plug

Tools Required: Socket set
Inspect the oil drain plug for tightness.
If leaking, remove the drain plug, replace the sealing washer, and re-install it to the manufacturer’s torque specifications.

5. Refill Engine Oil

After repairs, refill the engine with the appropriate type and amount of oil as specified in the owner’s manual.
Start the engine and let it run for a few minutes while checking for leaks.
