White smoke only on start up sr20det

Hey guys just recently had my head gasket done, i brought my cylinder head to get machined and pressure tested, guy saids it was good, so i got it reinstalled and got it started. I was wondering if this smoke might mean im still burning coolant. It kinda looks like it and it happens for about 10 mins after the car is warm then it goes away. Its not very much and im pretty sure it isnt vapor because the smoke moves very quickly. Ive had the car for 3 days now and driven it. Maybe my timing could be making this happen?!? I know i may have to retime my car again. My coolant hasnt gone down so im not too sure if im burning coolant. Maybe my oil is still mixed with coolant? Ive done 3 oil changes including this one. Im using royal purple hps 10w30. Im not a pro at all this stuff sorry. THx!

Maybe valve stem seals.
Any oil in the charge piping?
Run a quick compression test to see what that looks like.

Water is a byproduct of combustion;

When you shut your vehicle off, water is in the exhaust is gaseous form. As it cools, it will condense onto the plumbing.

Depends on the temperature overnight, relative humidity, condensation may be found on the exhaust in the morning when you first start your vehicle. It is therefore normal to see white vapor exiting the exhaust as the exhaust warms up on a freshly started engine.

If your compression is good and even, and you do not detect any smell of oil/fuel or any blue/black smoke, and the white vapor gradually disappears as the engine warms, it is likely a normal occurrence.

I dont think its vapour i compared it to the smoke coming out of my suv its coming out very quick and it looks thick. I will do a compression test as well. I also think it could be my turbo seal is going because it is water cooled and oil cooled maybe the coolant seal is wearing? Like i said it only happens when i first start the car. It goes away after about 10 mins after the car is warm.

Well if unsure I always say smell test it. Get your senses alert and what does it smell like? Are you running coolant (green stuff)? Does it smell like coolant? Does it smell like anything?

If it is smell-less and you ARE running a coolant (which would normally be a stinky odour I believe) then chances are its just condensation.
bad turbo seals that smoke white coolant usually do so at stoplights (engine neutral low rpm) and it gets worse and worse
