The pan it's self is not damage by the rust or dust . Befor the engine was shipped to here . The whole engine was just sit on the oil pan for a Long time and the wight of the diesel engines wight damage the oil pan. after we install the engine on mount, the pan was hinting the front driveshaft and make a hole on the edge, So I graiding the damage part to smooth and put special pad inside,To field the gap of the hole,
After the pad was dry and I put a blue color glue gasket to make there no space between engine and pan.
