During engine inspections, is it safe to use high pressure water directly on seals and electrical components?

Using high-pressure water directly on seals and electrical components during engine inspections is not safe because it can lead to several issues. High-pressure water can penetrate seals, which are designed to keep lubricants in and contaminants out. When water gets past these seals, it can cause internal damage, leading to premature wear, corrosion, or complete failure of engine parts.

Electrical components are also particularly vulnerable to high-pressure water. Water can enter connections, disconnecting wires, and potentially cause short circuits, which can damage the electrical system or even result in a fire hazard.

Therefore, it's crucial during inspections to use alternative cleaning methods that don't involve high pressure, such as using a low-pressure wash or a soft cloth, ensuring that both seals and electrical components are protected from damage. This approach helps maintain the integrity and functionality of the engine over time.
