Thread: squealing in engine bay

How about the belt. I guess you have checked the movement in the other pulleys while the belt was off?

I have a manual discovery 2 and the spigot bearing makes a noise when the clutch takes up on take of at slow speeds. The exhaust manifold can make a noise like a belt slip squeal too if it's leaking.

Yes checked all other pulleys while the belt was off, it is a new belt too, i even gave the back of the belt a bit of a sand paper rub, so it wasn't as shiny like a new one.
It is a 2001 D2 TD5 Auto.

Could it be chirp from a failing front prop shaft uni? If so, you should check it as a matter of priority.

exhaust manifold gasket/broken stud?

If it's non-ACE there is a idler pulley located under the air conditioner pump that played up on mine.
I've also seen a belt change stop the squeal, not sure on what brand was the better one though.

As mentioned make sure you check the front tailshaft universals.
Particularly the ones of the Cardin joint, worse case is they let go and take out the transmission housing.

Blaze mentioned the exhaust which can have a similar sound.
Usually the nuts at either end of the manifold come loose or the studs break.
If it's leaking there should be a small black soot trail between the manifold and the head.

Check your turbo hoses aswell

Prop shaft. Spray some lube in the unis. If noise disappears you know the culprit.
