Great truck. Motor runs. Motor noise. I assume it is the oil pump as when traveling home the noise started and the oil pressure indicator dropped to zero. It subsequently went back to normal but noise continued. Didnt overheat. Could be a timing chain issue as they are common with the Ford 4.6 engine. I havent had it looked at by a professional. High mileage but doesnt show it. 336069 miles. Is the F250 model of the F150 with beefed up suspension. Some paint flaws. Leer topper. Geolander tires with little mileage. Triton V8 engine. 4WD. Transmission has a mild syncro problem 1st to 2nd gear. Had to have a truck for business so bought another immediately.
