Solution

1. Preparation

Tools Required: Socket set, torque wrench, oil catch pan, rags, flashlight.
Ensure the engine is cool and parked on a level surface.
Disconnect the battery to avoid any electrical issues during repair.

2. Identify and Repair Oil Leaks

Sub-steps:
1. Locate Leaks: Use a flashlight to identify oil leaks around the engine components.
2. Replace Damaged Gaskets: If the valve cover gasket is leaking, remove the valve cover by unscrewing the bolts, clean the mating surfaces, apply a new gasket, and reassemble with specified torque (usually around 10-12 ft-lbs).
3. Fix Oil Pan Leaks: If the oil pan is leaking, drain the engine oil into an oil catch pan, remove the oil pan, clean the surfaces, apply a new gasket, and reinstall with torque specifications (typically 7-9 ft-lbs).

3. Check and Replace Oil

Sub-steps:
1. Drain Oil: If the oil is burnt or contaminated, drain it completely using an oil catch pan.
2. Replace Oil Filter: Remove the old oil filter with an oil filter wrench and install a new filter, lubricating the rubber O-ring with fresh oil.
3. Refill Engine Oil: Use the manufacturer's recommended oil type and fill until the dipstick indicates the proper level.

4. Inspect and Repair Exhaust System

Sub-steps:
1. Examine Exhaust Components: Look for signs of oil burning on the exhaust manifold or pipes.
2. Replace Damaged Parts: If necessary, replace any damaged exhaust components and ensure all connections are tight.
