The engine has cosmetic spray and I don't know if it has sealant or not, but you can inspect it. However, the engine is in good condition by God's will and was fully replaced four years ago with original parts, new radiator, and perfect chassis. There is a dent in the rear bumper that needs replacement and fixing the dent with paint. The front bumper is newly installed. The engine model is 2003 converted to 2004 model, original agency from Yarab. The engine hasn't been smoked or tampered with!!! I accept exchange.
