What are the consequences of not closing the oil cap?

[VanMia]

The consequences of not closing the oil cap are as follows: 1. Oil spillage: If the oil cap is not tightened, the oil will spill into the engine compartment while driving, causing unnecessary losses. 2. Carbon buildup: Since the engine operates at very high temperatures, the oil attached to it will not only evaporate when heated, accompanied by a pungent odor, but over time, it will definitely form a thick layer of carbon deposits, which will affect the engine's cooling efficiency. 3. Safety hazards: If the oil flows onto some wiring, it can easily cause a short circuit, or even spontaneous combustion. Therefore, the consequences of not tightening the oil cap are very serious. Once discovered, it must be dealt with promptly to avoid the danger of a short circuit.
