Alfa 156 ts

156 weird noise

Hi all, recently bought a 156 2.0 ts selespeed. I'm really enjoying the car but have a noise that is spoiling my fun! When the revs are between 2000 and 3000 rpm I get a strange rattling noise coming from the engine. It does it while moving or stationary. Has anyone else had this problem? Any help would be great!

Plenty about this on the forum if you do a search.

Most likely culprit is the manifold bracket. When it cracks (and they all do) it rattles like a tin of nails.
Could also be the manifold heatshield in the engine bay that is cracked.
Lastly, could be the exhaust bracket in front of the cat that is loose (mine was and rattled like a skeleton having a **** in a biscuit tin)
