 So this morning on my way to work I noticed the E30 making a funky noise. Its sort of like a whirring or light grinding sound coming from the rear of the car. Gets louder the faster I go. Completely quiet when car is stationary. Car still drives and shifts smooth though. I'm thinking it's the diff. Anybody have a S3.xx diff they wanna gift me?

 ive never had valve float , my ecu is chipped and revlimiter is only at 6800 rpms.
 But im pretty sure the cam is 100% stock. The PO said they did head work but never said anything about a cam. I still want to get a re-grind, smothing with a aggressive feel and tune :D Comment

 Take the ECU chip out or it will happen again my friend,take my advice and take it out.:hitler: I am not kidding either.ive never had valve float , my ecu is chipped and revlimiter is only at 6800 rpms.
 But im pretty sure the cam is 100% stock. The PO said they did head work but never said anything about a cam. I still want to get a re-grind, smothing with a aggressive feel and tune :DYour signature picture has been removed since it contained the Photobucket "upgrade your account" image.

 THATS A BIG NO NO :tsk: Because you will have around 500 to 600 rpm of valve float.
