Foreign objects inside the engine—such as screws, gasket fragments, or small tool pieces—are more common than many drivers realize, and the damage they can cause is often severe. Metal debris entering the combustion chamber can scratch piston tops and cylinder walls, or in worse cases, break piston rings. Larger objects may prevent valves from closing properly, causing loss of compression or engine misfire. Some fragments can also lodge inside the turbocharger or intake passages, creating secondary damage. In short, any hard object entering a cylinder can quickly turn a minor mistake into a costly overhaul.
In these situations, using a digital inspection camera or engine borescope is the safest and most efficient diagnostic method. Modern borescopes feature high-resolution lenses and adjustable camera probe with light, allowing direct observation of the cylinder, intake ports, and valve areas without engine disassembly. For narrow or curved passages, a flexible scope camera can reach areas that are otherwise inaccessible, enabling fast confirmation of whether the foreign object remains or has already caused damage. When evaluating internal cylinder conditions, a dedicated cylinder bore camera provides the level of detail needed for accurate diagnosis.
3.How Should Auto Repair Shops and Vehicle Owners Respond?
Once a foreign object is confirmed inside the engine, the vehicle should be stopped immediately to prevent further damage. Repair shops typically use the borescope to pinpoint the object’s location and then remove it using long-reach tools, magnetic pick-up devices, or compressed air. If the object has caused visible scratches or deformation, further disassembly or component replacement may be required. When there is uncertainty about whether the debris has moved deeper into the piston or valve area, multiple viewing angles with the borescope should be used to ensure a complete inspection. For vehicle owners, prompt diagnosis and action are essential to prevent extensive engine damage.
