White puffs of smoke from the drivers side more near the cowl are

If you got smoke this is NOT a good thing! Get a Good Auto Electrician to check ALL your vehicles wiring as electrical smoke means something is burning! Simple rule, Fire plus gasoline is NOT a good idea!!

Leaky injector

is it puffs of smoke or like a vapor. does it smell like coolant

Yes the white smoke from the rear at the wheel means that the breaks need to be changed/replaced.

The white smoke is a concern. When there is white smoke present after the engine has reached operating temperature, this can be a sign of antifreeze getting into the combustion system. That can come from a couple of places depending on the vehicle. The most common place is from a leaking head gasket. If this engine has at one time been significantly over heated that is a strong possibility.
The mixing of coolant with the combustion can also cause very poor performance and stalling.

One of the tell tale signs of coolant in the combustion area is a sweet acrid smell from the exhaust, similar to the smell of maple syrup.

If this is the case the only permanent solution is a head gasket replacement and head reconditioning. This is a major expense and undertaking.

White smoke on startup could be a head gasket leak between the water jacket and the cylinder. Won't always show in the oil. Antifreeze makes it smell oily or sweet. Compression test will tell for sure. Bluish is oil that was burned. White is usually water or oil into exhaust after combustion.

White smoke means water/antifreeze entering the combustion chamber(s) or intake passages. Suspect a gasket leak somewhere (tighten all intake manifold nuts and bolts). Check all radiator and heater hoses for leakage and hose condition.

antifreeze i think,heater matrix leak ,try putting a rad leak stopper in

If its in the engine compartment there is an antifreeze leak..If it inside the car like like near to the windshield, you have a bad heater core. Good Luck contact me if you need more help.

white smoke is water
blue smoke is oil.
nest time try and smell the white smoke see if it smells sweet?
if it does its antifreeze.
and also black smoke is fuel (like a leaky injector )
hope this helps
