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 FOB vehicle quotes are typically valid for 72 hours (as domestic retail vehicle sources can be sold at any time); sea freight quotes are valid for 7 to 14 days (depending on shipping line changes). After expiration, prices need to be recalculated based on real-time exchange rates and domestic procurement conditions.

If General Average is triggered, all cargo owners must share the rescue costs. If you purchased marine insurance with a "General Average included" clause under CIF terms through us, the insurance company will cover this high shared cost for you; if you are an uninsured FOB buyer, you will need to pay it yourself.
