Welcome to Justanswer ! my name is XXXXX XXXXX i will do my best to assist you with this problem
when it was smoking before you shut the engine off was it running on all 4 cylinders just before you turned it off ?
now the big problem here is coolant is filling up the crankcase
this can only happen with a bad head gasket, cracked cylinder head or a cracked engine block
since no coolant is getting into the cylinders them selves that's what your up against im sorry to say
the best approach is remove the cylinder head and do a very good visual on the gasket if you see it blown out replace it and have the cylinder head sent out to be planed flat and checked for cracks and it should be ok
if the head gasket looks good send the head out to be pressure tested and checked for cracks and flatness if any of those show up during inspection have it planed of if cracked replace the head
if the head checks out and the head gasket checks out the block is cracked and will need to be changed im sorry to say
