• Verification of engine identification numbers.
• Determining consistency of reported accidents and engine damage & repair.
• Inspection of damaged engine (including marine and industrial) and transmission gearboxes to distinguish between accidental damage and wear and tear.

Engine breakdown in cars, buses and trucks is often attributed to an accident. It may be claimed there is a loss of lubrication, with damage occurring thereafter as the vehicle is driven or towed. Alternatively there may be a fire and the engine is claimed to be damaged by fire.
