Technical Where can I find these bolts?

[DodgieOdgie]

Hi all, just a quick one. I have a 1.4 petrol punto evo and when my car is running there is a slight ticking noise which speeds up when I accelerate. Once engine is warm I don’t hear it as much tbh. I have been told that it is this missing bolt which could be causing the noise? Is that correct? And where can I source these bolts or what is the correct name for when I’m searching for them? Thankyou

It's not just a bolt (stud) to be replaced. First remove the old broken one...

Threads are standard/normal M8, nothing fancy, length is in the links somewhere (about 40-45 mm).
If studs are popping out, the manifold is probably warped. New studs will break again in 2-3 years max.

Exhaust manifold studs (and you'll need a new nut too).

Chances are you;ll need the manifold off to replace the gasket and find a brolen stud in there. Or if you are lucky then it's vibrated out.
