i have a 2000 f150 5.4 V8 triton and every time i speed up i hear a wierd ticking noise, anybody have any idea what it is making this noise?

colton

is it a metallic sounding clicking noise, or more of an airy sound?

Txusboi21

not really metallic well in my opnion, i can only hear it if i have my radio all they way down it sounds like its coming from my speedomoter but i have no idea its annoying and only happens when i speed up fast like pasty 2200 rpm's

Probably an exhaust leak. Check for carbon deposits around the manifolds and joints in the exhaust system.

colton

mines done that for a while, but if you think about it while listening you can tell its a really air-like sound. when i bought the truck an exhaust manifold stud was broke, and ever since i replaced them, its done it. i figured maybe the manifold was slightly warped from having the broken stud so long?

BigIrish

Yes, I think Ford recommends replacing the manifolds or having them milled for flatness on trucks which have broken studs.

yeah id do that if i didnt have bigger problems on my hands, dang it. dont know if you saw the thread i just posted, but thats what im talking about. cracked 4wd shaft. and im guessing it isnt just the case, but whats inside too. dang..

I saw that other thread and considering that axle shaft doesn't carry any vehicle weight, unless you see an impact mark on the tube somewhere, you probably fragged the shaft inside.
