the clicking i think your taking about is on shutdown, what that is is the crankshaft rocking back and forth due to compression, after you shut her down the momentum of the crank turns untill the compression stroke of the next piston is enough to kick it back the other way a bit, your just hearing the clearance in the connecting rod bearings, as for the chirp its the belts, most big diesels do it, its all normal, worry if it gets louder, indicates worn main and rod bearings.
