Best Answer

my grand am had an engine knocking noise. it was the intake manifold gasket was going bad. it was leaking coolant into my oil. look at your oil to see if it is a white milky color. if it is then you need a new manifold gasket which sucks. it takes a long time to do by yourself. or you can take it to a place that charges you $1000 to do. but if you can. do it yourself

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.
