Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Disconnect the battery to prevent electrical shorts.

2. Identify and Fix Oil Leaks

Tools Required: Socket set, torque wrench, oil catch pan
Inspect oil pan, valve cover gasket, and other potential leak points.
If leaks are found, replace the defective gaskets or seals.
Tighten any loose bolts to the manufacturer’s specifications using a torque wrench.

3. Change the Engine Oil and Filter

Tools Required: Oil filter wrench, funnel, oil catch pan
Drain the old engine oil into the catch pan by removing the drain plug.
Replace the oil filter using the oil filter wrench.
Fill the engine with new oil as per manufacturer specifications (check the owner’s manual for oil type and capacity).

4. Clean Residual Oil

Use a degreaser to clean any residual oil from engine components to prevent further burning smells.
Rinse and dry the area thoroughly before reassembling.
