Knocking Noise On
1983 General Motors (Pontiac) 6000 Vehicles
With 2.5L L-4 And 2.8L V-6 Engines
Pontiac reports that some 1983 model 6000 vehicles may exhibit a knocking noise from under the hood which could be caused by loose torque converter to flywheel bolts.
Loose torque converter bolts sound very much like a bearing knock and will give several raps on a quick acceleration (engine running free). With the vehicle's transmission in gear, the noise may or may not appear at idle depending on the idle smoothness.
Before attempting to repair any bearing-type knock, check the torque converter to flywheel bolts.
