Noise coming from engine in Oldsmobile Cutlass could be as a result of an oil leak in the rear of your engine. This makes the gears to wear off leading to severe knocking noise.
The noise is the teeth on the flywheel grinding on the teeth of the starter. Check to see if the starter is loose, this is the most common cause of that noise.
