Visual inspection using a videoscope has become an essential part of both preventive and corrective maintenance for diesel engines, whether in generators, industrial systems, or onboard power units. A videoscope enables technicians to assess the internal condition of components without dismantling, in just a few minutes.
During an inspection, the technician inserts the probe through a glow plug port or injector well. It provides a clear view inside the combustion chamber, including the piston heads, cylinder walls, valves, and injectors. Thanks to its articulating tip and high-definition image quality, technicians can precisely identify cracks, wear, foreign objects, or carbon build-up.

There are many advantages to this type of inspection:
- Reduced mechanical intervention: The technician can make a diagnosis without fully dismantling the engine, minimising intrusive procedures.
- Time and labour savings: The inspection is quick and carried out on-site, with no need for heavy equipment or prolonged downtime.
- Comprehensive documentation: The technician can capture photos and videos to create a technical report, supporting traceability and communication with clients.
- Improved decision-making: Direct observation of critical areas helps to target maintenance actions and anticipate potential failures.
A videoscope is now a must-have tool for fast, reliable, and non-intrusive engine inspections. Our product range includes several models suited for this type of application. For example, the PRO S+ offers 4x220° articulation for hard-to-reach areas, while the PRO B is widely appreciated for its versatility.
