7.3 idi knocks when warm
Hello all! Awhile back I posted that I had a tapping sound on my 7.3 idi. I have replaced the injection pump, injectors, lifters, and it still knocks when it warms up. When it is cold, and you start it, it purrs like a kitten. A mile down the road, and only when you accelerate, it starts tapping...- mustangmalibu
