Good morning,

It sounds like maybe the engine is overheating. Normally the only cause of smoke from the engine would be an overheat causing steam to vent out.

If the smoke came from the exhaust pipe it could be an internal engine failure.

As far as the clacking noise goes, did it sound like fast clicking or slow, steady thumping?
