1997 Oldsmobile Achieva 4 cyl Front Wheel Drive Automatic 85000 miles
Rattling or knocking noise from under the hood at low speed. Goes away gradually as engine speed increases. At 20-30 mph and above the noise is gone completely. Noise started after I replaced the water pump, which means that I had to remove the timing chain to get to it. Not sure I got the timing chain reinstalled correctly. Car runs normally otherwise. No loss of power or acceleration. Tensioner problem perhaps?
