My car was in a flood, it sat in water for hours, water was moving and you could see it splashing under car. Then my son, drove the car a few blocks and drove through high water. The water did not come inside the car but when he returned home the car had a fast engine knocking noise.

insurance came a look at the car they said the think it came from need of a oil change, I only had the for 6 1/2 months. Could this be true or is there a defect in engine?
