anyone else notice this on there truck...i have the 5.4l right after it starts i hear a rattle/pinging sound for a few seconds then its gone...thanks

 

You should check out my other treads I have had the same problem and now am in need of a new motor...........

 

What oil filter are you using? Some folks on here hear this rattle when not using the Motorcraft oil filter. Something to check...

 

Whens the last time you changed your oil I know it sounds dumb but I had that same problem. I brought it to the dealer and they said that it was the cam phasers and that the oil need to be changed badly so they changed the oil and wala no more rattle it only does it when its cold right? I didnt believe it at first when they told me but it no longer makes the noise so I guess it wasnt B.S.

 

Mine recently started doing it also. I use the Motorcraft oil and filter. It is really annoying and I hope it isn't causing any problems. Funny how my truck just ran out of warranty and this started happening. I am hoping maybe I just got a faulty oil filter this time. Is there an easy way to tell if the oil filter anti drain back valve is bad.

 

i assume is motorcraft since they do it at the dealer. im almost in need of an oil change and im slightly past my 30kmi service...anyone know how much the 30kmi service costs? thanks andi hope i dont need a new motor

 

mine was doing that but it was caused from the weld breaking loose on the hanger for the flowmaster
