a. put the dip stick back in. There is supposed to be vacuum there
b. is it running rough when you have the dip stick out? If so, there's your problem. Having it out is causing a massive vacuum leak.
c. what color is the smoke? Only at idle when sitting a while or all the time?

smoking at idle

Reinstall your dipstick, vacuum there is normal. With the dipstick out you've created a vacuum leak and this will disturb the crankcase ventilation system and cause your engine to burn oil and idle rough. If after replacing the dipstick you still have smoke at idle, (you will need to drive for a day or two to clear the oil residue from your intake manifold), you probably need to replace your valve stem seals. There is an excellent shop in El Cajon that has tooling to replace the valve stem seals and clear the auxiliary air holes without disassembly of your engine.
