If you find oil residue on a vehicle's driving belt, what is the outcome for inspection?

Finding oil residue on a vehicle's driving belt is a significant concern during an inspection, as it can indicate a leak or potential failure of engine components. The driving belt plays a crucial role in the proper functioning of the vehicle's engine and accessories, including components like the alternator, power steering pump, and water pump.

Oil on the belt can cause it to slip, leading to decreased performance of these components and increasing the risk of mechanical failure. Moreover, the presence of oil can deteriorate the belt material over time, affecting its integrity and reliability. Because of these safety and performance implications, the presence of oil residue on the driving belt results in a vehicle failing the inspection. This underscores the importance of addressing any leaks or maintenance issues before the vehicle can be deemed safe and operational on the road.
