Summary

SOME SUPER DUTY F SERIES AND OTHER VEHICLES EQUIPPED WITH A POWERSTROKE DIESEL ENGINE MAY EXHIBIT A NOISE ABOVE THE NORMAL SOUND OF THE DIESEL COMBUSTION. THIS NOISE MAY SOUND LIKE A ROD KNOCK, BUT IT IS INTERMITTENT AND IT INCREASES IN INTENSITY AS THE ENGINE WARMS UP TO OPERATING TEMPERATURE. *TT
