Is it sweet smoke?

Check your coolant system, sounds like a bad coolant seal .
Fill up everything- even the coolant overflow bottle to the top-
Pull the eng fuse, leave the upper fill cap open-
Have someone crank- watch for excess ammount of water pouring out the top- or for bubbles.

Check for a gas/exhaust smell in the coolant.

Bad coolant seals= time for a rebuild .
