The black smoke indicates that the air fuel mixture is too rich (too much gas to the engine). The ticking has me concerned. Is it loud? Is it a tick or knock? Are you certain it is coming from the engine and not a belt driven accessory or possible exhaust leak (which can sound like a ticking)? Also, is the check engine light on?

Is oil pressure where it should be at an idle? As far as the black smoke, have you checked fuel pump pressure to make sure it isn't too high? Also, the coolant temp sensor can cause the engine to run too rich also.
