Rattle sound when cold (exhaust manifold shield)

Hello everyone,

Car began to rattle when cold, I found few screws broken on catalytic converter end, fixed it, but it still makes same sound.

My question is can you check the top of the exhaust manifold by removing heat shield from it, and can you tighten the screws that way.

Everything began when I ran over a bump, vibrations and rattling, Its way better now, but sound is still there.

Alfa 159, 1.9 JTS, 2006.

Thanks in advance.

I'm afraid I can't help you on that score, other than to suggest you get stuck in!

You could have either, cracked manifold, sheared studs, knackered flexi section, or have sheared the mount to the bottom of the engine.

If the noise goes when warm, you could probably eliminate broken mount.

You could have a look in the 147, GT and 156 forum as they also used these engines, and might be a bit more info.

Best of luck!
