We use two steps: 1. Insert a medical-grade endoscope through the spark plug hole to visually inspect cylinder wall scratches and carbon buildup on the piston top; 2. Extract an engine oil sample to check for large metal debris or emulsification (caused by coolant leakage).
Our foreign versions of the report standardize terminology and include illustrations. For example, instead of just writing "control arm failure," we specify "Lower Control Arm Bushing Torn" to help your local technicians identify the issue directly.
No hidden fees. The total amount on the FOB/CIF invoice is the final amount. We rely on professional supply chain operations to earn a reasonable margin and do not allow any sales personnel to privately request kickbacks or service fees from you.
