White smoke is water/antifreeze mixing with fuel burning off causing steam more than likely blew head gasket - slight noise can be the thinned oil/anti-freeze mixture running thru ur engine letting metal hit metal -dont run engine if let run to long in this condition will do extreme damage that only an engine replacement will fix

If u r not losing any coolant. Than have the fuel regulater check. If this is ok than check it for possible blown head gasket.

Head gasket has gone white smoke is water vapout (steam) best advice here is to trade it in on plan renewel
