2002 E46 M3 - Need help determining what this noise is.
Hey guys, the vanos system on my nephews E46 M3 sheared off the tabs on the exhaust hub ,so the entire system had to be rebuilt. All the parts used for the rebuild are listed below. Now that that it's back together there is a strange knocking \ rattling sound between 2300 - 3000 rpm. It's very apparent in person and sounds terrible. The timing chain tensioner felt like it was functioning properly.
Any suggestions on what could be causing this noise? Specific things to test? Throw the car into the lake and buy a new one?
We are trying to avoid just throwing random parts and money at this.
