This is a rather odd situation. I have a 70 Chevelle with a 6.0 LQ9 and 2 stock 86/87 GN turbos.
I noticed a buzzy vibration in the car at around 1000rpm, brake torquing in drive.
While having someone brake torque the car I listened to various components with a long screwdriver and everything is very smooth -except- the drivers side turbo. It's actually difficult to hold the screwdriver against the compressor cover as it's such a strong vibration. Passenger side turbo is smooth.
Makes me think it's the turbo itself but it seems odd that it doesn't smoke or make noise under wide open throttle, just a very narrow rpm range down low.
Anyone else notice a vibration from a failing turbo? Thanks!
