I have a 2003 F-150 supercrew 5. 4l 2x4, from day one, a hollow knocking noise is heard at idle most noticeable when in gear at idle, or low rpm. I have had it into Ford several times and nothing has been done. We even started another truck on the lot (same year, engine ect. ) and the noise was not found on the other truck. The service manager states he does hear the noise but Ford does not know what it is therefore they cannot fix it so no attempt has been made to find or repair it (my truck has not been on the rack even once). Please advise as to what I can do to resolve this problem.
Hollow knocking noise in the 5. 4 engine most noticeable when cold. Ford and the dealer tell me to put up with it because it is normal. Something about piston clearances or slap. I did not pay $30,000. 00 + for a new vehicle to listen to it knock in the mornings when I start it up. Ford is aware of this noise in the 5. 4 and I would like someone to look into this because they are not willing to do anything about it.
