scratching noise on start up ..

just like the title says, when the car is cold i go to start her and there is a scratching scraping noise that goes with the belt rotation, its intermitent as not all the time just at certain spots, the belt is tight and cant see anything in the way to be rubbing , it has a metal on metal noise ,, but when the car warms up the noise goes away totally,
ive checked the belts, oil and basic obstructions everything seems ok
does anyone have any ideas ??
 
just got the car over last summer, had the oil done at the dealership since it was free so im assumin its a motorcraft one .. would be pretty funny if it wasnt,
its goin in tommorow for oil and tranny service ,
i hate payin the money but since its still under warrenty i dont wanna mess with it even though i could easily do the fluids myself

whats needed to remove the belt gotta make sure its a tdc or just take the thing off and check things out and replace ??
 
Update:
Well i brought it down to the dealer friday for the service, and i explain all the stuff wrong in addition to the problems i posted here, intermitent start, and a clunk noise in the rear,
the tech comes back in and starts tellin the service manager all this stuff,, and im like great my ass is startin to hurt from how much this is all gonna cost. lol
The intake manifold where the thermostat housing sits is cracked and leaking coolent in the intake valley and i did notice some corrosion on the underside but honestly forgot about it
next the rear: told him what was up and that it only has a one wheel peel so i had a feelin it needed a rebuild and gears were already going through my mind lol
so new bearings and clutches are going in to take care of the rear
and a new intake manifold and whatever else goes with it
now good news since i did get it "certified used " it has a warrenty that covers all mechanical stuff thank god ,
This doesnt make me happy that i just got it over the summer and all this is wrong , the person must have had alot of fun with her and didnt take care of her to well
sorry for the long post but had to vent it out

Anyone know any good shops in the upstate NY area instead of the dealers :SNSign:
 
That's why I would NEVER buy a "used' Mustang. Even if it's certified.

Those two things that went wrong with his car are very common and even ones that are not beat on had had these problems..

Nothing wrong with a used mustang as long as you find the right one.

Unless you see where a cage was welded in or where nitrous brackets were then you should be ok.
