Oh...then it's just condensation.

It depends on how much white smoke it is.

Take off the radiator cap and see if there's oil mixed in with the coolant, dead give away for a blown HG.

you both need to do some more reading before posting. condensation WILL NOT get into the cylinders of the engine....ever! unless it leaks in from somewhere.

a cracked cylinder wall, a failed HG, or another seal would allow coolant in.

since its small i'd imagine you either got a. the wrong HG or b. you bought a one in a million faulty HG.

replace it and find the leak.

Or maybe the head gasket wasnt installed properly. Did you replace the head gasket, or did a shop do it? If the shop did it, do they guarantee their work? If you did it, did you torque down the head bolts from the inside-out? Or, if Im not mistaken, your rings could be bad too, causing you to burn oil. Check your oil level on your dipstick......remember to take it out, wipe it, put it back in, then check it.
