My car used to have that same noise... a knocking/ticking noise coming from the near base of the engine at the crankshaft pulley... couldn't figure out a dang thang what could be making the noise... til I looked at the serpentine belt. A large 5 inch long strip of the belt was grove-less and was causing a heavy snapping/ticking/knocking noise that was fairly loud and occured mostly when the engine compartment heated up and the belt stretched a little, but sometimes while cold. Check your belt, seems stupid, but it fixed my noise.
