Question
once i turn on my car alot of smoke from the exauhst is comming out but i mean alot and i think its the engine well its makeing a noise once i turn it on why is it doing it

Answer
Depends what the smoke is.  If it's white and clear or sweet smelling, it's likely coolant and likely a head gasket.  If it's dark or oily, it's likey rings/valves etc, and burning oil badly.

either way, it's likely a major repair.
