Losing coolant with no apparent leaks, White smoke out the exhaust that has a sweet smell to it,
Losing coolant in a vehicle is not a good thing. It is best to check all seals and all bends in tubing.
You may have a bad head gasket and it may be leaking from that. Why when cold i dont know, but if you are losing coolant it may be the head gasket.
have the head gasket replaced
If you are losing coolant, you probably have a bad cylinder head gasket. Too much coolant system pressure will drop your engine oil pressure.
Have it pressure tested and repair the leak.
could have a crack in it that is leaking under pressure
If there really is no leak then it is likely a head gasket allowing coolant to leak into the cylinder and go out the exhaust as steam.

check your oil to see if you have coolant in it. if you do your intake gasket needs changed.
sounds like a leaking head gasket have a pressure chek done on cylinders and cooling system
