2003 Mazda Protégé 2.0
I just replaced had my head gaskets, water pump, timing belt and a new head (old one warped) put on after my car overheated. (Due to the failed water pump).
However the past couple of days (starting for the first time etc., when I start the car (cold start-usually sitting over night) white smoke will come out of the exhaust. The smoke is pure white and smells sweet. It comes out at a steady rate and stops as soon as I drive (within a minute or so, I see nothing trailing behind me).
Also, it only smokes out of the exhaust when it’s a cold start, if I drive it and then start it again, no smoke.
I’ve changed the oil, put Heet and Lucas injector cleaner in it, but it still seems to smoke upon start up.
The oil and coolant levels remain the same and it does not over heat.
The mechanic who did the job said it’s just coolant burning off, but I feel, I’ve driven it too long for it to keep happening. ( I drove about half a tanks worth of gas)
All the parts have been replaced/new. It's been about 3 days since it was fixed and I started driving it.
Any Ideas?

You're getting coolant into the exhaust again. Sounds like it's coming apart again.

What do you mean by "Coming apart"?
It wasn't done correctly?
All of the parts are new/replaced even the head was warped so that was replaced.
Any suggestions or test that can be done?

Coming apart means that you are removing the head again. Either something failed since or something was not done that should have been.
Did you do this job yourself?
Was the head gone through by a machine shop?
Were new head bolts used?
Has it gotten hot at all since the job was done?

I'd let it sit over night and then in the morning take out the spark plugs. With a flash light look down into the spark plug holes and look at the top of the pistons. You may have to rotate the crank to get a piston up so you can see it. Look to see if there is any coolant laying on top of the pistons. If you don't see any coolant laying in there, you shouldn't worry about it as long as your coolant level is remaining the same.
Depending on how badly the engine was burning coolant before the repair, your exhaust system might have been full of coolant. It possible you smelling the coolant that had collected in there along with seeing the normal condensation burning off in the exhaust when starting it on a cold humid morning.

Judging by the symptoms here, I seriously doubt this is residual. It started after the car had already been used and apparently didn't smoke at first. Also, the fact that it only happens cold also point to overnight leakage.

Do you think pulling the plugs and looking into the cylinders for coolant would confirm overnight leakage? You could let a coolant pressure tester sit on there overnight. If there is coolant getting in the combustion chamber after sitting, you would really see it then.
Maybe stick a garden hose in the O2 sensor bung hole and wash the exhaust system out..LOL

I would pull all the plugs and leave it under pressure and see what happens. Every head gasket job that I ever did never smoked past the first hour of use.

Hopefully a licensed shop did this job because if there is a chance you have coolant getting in there, at least it is under warranty.
