Tell somebody to rev the motor and check where the problem is from, otherwise remove serpentine belt, if it's a supercharged model remove supercharged belt before, and remove the accessories belt ! tell him to start the motor a short time to see it the knock sound is there or not, if not check each pulley if there's any loose or strange noise while turning them !

97 buick lesabre.its knocking then stalls out.and starts right back up.no smoke.


Knocking at acceleration? Or Idle? Knocking could be a rod, piston slap, or tappets (rocker arms). If its a rata tat-tat its upper engine or tappets. A heavy thump is usually from the crank.

1997 LeSabre has engine "knock"


If it knocks at 50 it will knock sitting still if you race it up. Is the oil pressure good? These motors hardly ever have a bearing problem. The only knock problem was the harmonic balacer that comes apart and knocks. The rubber falls apart and it will make a knock sound all the time, more with the ac on. If you have a knock at 50 or highway speed only you may need a outer tie rod end only. Get the front end checked as they will make a knocking sound on the highway. reply

KNOCK SENSOR


When a knock is detected, it sends this information to the computor, in which retards the ignition timing. If the sensor is bad, it will do this more often than not.
