3.1 motor has loud knocking?
if it sounds like the knocking is coming from the bottom of the engine i would bet it was the rods or rod bearings may be worn. if the knocking is on the top ,then i would have the lifters and or the rocker arms checked.
Pontiac grand am and it is knocking at the back of the motor what could be wrong?
Internal knocking inside the engine is almost always a sign of worn bearings. Crankshsft, or rod bearing would be my guess. The fix, if it is internal, is overhaul. Before opening it up, make sure the knocking is indeed coming from inside the engine.

Knocking noise coming from the drive shaft?
On older cars and all trucks use a coupler called an u-joint to join the trans, driveshaft and rearend together to power the car or truck. This coupler has tiny little bearings in it. When the bearings run out of grease or badly worn this will cause slop within the coupler. bottom line is it sounds like you need a new u-joint.

Knocking noise when engine is idling?
Lucas (oil additive) it and pray..if its a rod just drive it easy..if it is spark knock use better gas. answer the door sorry bout that, but if engine is knocking is it at idle, under load,etc knocking can be caused by piston slap,(worn out rings),bad bearings,or simply have engine tuned, all depends where knock is coming from
What is the cause of a knocking from the front end of a 2000 Pontiac grand prix when driving at low speeds?
My 2000 Grand Prix would have a low-speed knocking noise coming from the drivers side as the CV axle was failing. The loss of lubrication in the CV Boots allows the joint to make a knocking/tapping sound at a low speed. If the knocking is coming from the engine compartment, then it could be an entirely different problem.
