Sick sick about this. This truck has not been driven hard. no off road, no towing , never been over 80 mile per hour. They are taking engine apart to make sure no metal shavings. I will never trust the truck now. heart broken. this is my 3rd ford truck, also 2 explorers with many problems, I think this is my last ford. my uncle worked for fords for years on the ford racing teamm at detroit drag way. sorry uncle bill but i think this is my last ford.
