During the inspection of the engine, what should be checked for?

During the inspection of the engine, it is essential to check for pressure leaks. This is because pressure leaks can indicate a serious issue within the engine's systems, such as the cooling system or the lubrication system. For instance, if there is a leak in the cooling system, it could lead to overheating of the engine, which can result in catastrophic engine failure if not addressed. Ensuring that there are no pressure leaks helps maintain the proper functioning of the engine, which is crucial for the safety and performance of the vehicle.

While fuel leaks, oil leaks, and coolant leaks are also critical checks during an engine inspection, detecting pressure leaks presents immediate risks that could compromise both the mechanical integrity of the engine and the safety of the vehicle. Thus, focusing on pressure leaks aids in preventing potentially hazardous operational conditions.
