Is Oil Stain on the Engine Indicative of an Oil Leak?
1 Answers
If the oil stain is caused by a loose engine oil seal or aging sealing ring, leading to seepage rather than an actual oil leak, then it is not a serious issue. An oil leak, however, refers to oil dripping due to faulty engine components or assembly problems, with a relatively fast leakage rate. In such cases, immediate repair is necessary. Relevant information about automotive engines is as follows: 1. Introduction: The car engine is the device that provides power to the vehicle, serving as the heart of the car and determining its power, fuel efficiency, stability, and environmental friendliness. Common gasoline and diesel engines are both types of reciprocating piston internal combustion engines. 2. Classification: Based on different power sources, automotive engines can be categorized into diesel engines, gasoline engines, electric vehicle motors, and hybrid power systems, among others.
