relay
Collapsed hydraulic lifter? - try a quart of mystery oil
SEAT BELT
you may have a bent valve
ON the 2006 impala that whining noise is actually the electronics when you accelerate. Its more or less electronic pulses/signals My 06 Impala is the same.
nail in tire, or rock
The belt is slipping.
CV Joints? Rocks in the tire tread?
The most common cause of the whistling in a 2003 Impala is a vacuum leak. Any of the lines under the hood could be causing the noise.
A gasket leaking will cause this noise. Did you torque to the right specs and in the right sequence then retorque after 3 heat cycles.
Collapsed hydraulic valve lifter? Rocker arm (valves) need adjusting?
can you elaborate? engine noise? stationary/moving? ticking, tapping or a definite knocking?
