5.4 Problems!!!!!!!!!!!!!!!!!
So I have a 2004 F-150 that just passed 80,000 miles and a month ago it started making a very loud noise on startup, but only cold startup, meaning if I haven't used the truck in about three hours. Now I went on youtube to research and found a video of a truck making the exact same noise! Here is the link:
04 f150 cold start knocking noise



Can anyone verify what this is??? Some poeple are saying cam phasers and some are saying I'll need a brand new engine! Thanks everyone

 

i just bought a 2004 with 102000 and it does this to. It sounds like a diesel for about 4-5 seconds then runs fine. Doesn't matter cold or warm. I would also like to know what this is

 

That's a really odd noise. Wondering if it isn't the engine knocking against something due to motor mounts or something
