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 electrical shorts.

2. Identify and Remove the Faulty Component

Oil Filter Replacement:
- Locate the oil filter and use an oil filter wrench to remove it.
- Ensure the rubber O-ring from the old filter is not stuck on the engine.
Valve Cover Gasket Replacement:
- Remove any components obstructing access to the valve cover (e.g., intake manifold).
- Unbolt the valve cover and carefully lift it off.
Oil Pan Gasket Replacement:
- Drain the engine oil completely using a drain pan.
- Remove the oil pan by unbolting it from the engine block. Inspect the gasket for damage.

3. Clean and Install New Gaskets/Components

Clean the mating surfaces of the engine and the component being replaced.
Apply a thin layer of gasket maker if required (follow manufacturer specifications).
Install the new gasket or component and torque bolts to the manufacturer’s specifications:
- Valve Cover: Torque to 10 Nm (7 ft-lb).
- Oil Pan: Torque to 10 Nm (7 ft-lb) in a crisscross pattern.

4. Refill Engine Oil

Reinstall the oil filter, ensuring it is properly tightened.
Refill the engine with the appropriate oil type as specified in the owner's manual.
Reconnect the battery.

5. Final Checks

Start the engine and allow it to idle for a few minutes while checking for leaks.
Inspect all replaced components and surrounding areas for any signs of oil seeping.
