Ok I drive a 2.4L LE5 but I put the M62 supercharger on it with the zzp bolt on kit(which was a disaster btw...but that's a different thread lol) I have had it on for about 100 miles and it is making this terrible noise from indide the supercharger...like a rattling noise...does anyone know what it could possibly be? Thanks for your time

 

Is it only at idle, get louder at accel or WOT? little more info. Any codes?

 

It does it during everything...idle accel and wot...and no...no codes...no loss of boost or anything

Anyway of describing the noise? Rocks? Screaching?

 

Sounds Kinda of like rocks in a can rattling around

 

Believe thats a bearing. I'd have to lookup some more info on it.
