Double check the alignment of the timing belt, crankshaft to valves.

Which engine???

Take off the drive belts and start engine to see if noise still is there and go from there.

it has the 3.0 motor in it.... due to the weather one of the freeze plugs came out of the back of the block... would that be the reason its knockin?
