it looks white but i can only see it in the mirror it may have a blue tint

Is there any fluid on the underside of the car? Where? What color is it?

Could be an oil pan gasket or trans leak...

no fluid under the car. if it was a leak wouldn't it smoke all of the time?

Is car auto or stick?
Smokes under load only.Correct?
Colour is white-as in blown headgasket?
Might be your vaccum modulator.
It controls the upshifts of the autobox.
If you follow a rubber hose(small) ,at the base of the carb,it connects to a pipe-leading down the pass side of the car.
There it will be connected to a hose again that goes to a funky looking canister.
If you disconnect the line at the base of the car-temporarily-,and the smoke vanishes,you have a busted diaphram in that modulator.
A new modulator is VERY cheap and VERY easy to install.
What gives the smoke in that case,is the motor burning auto fluid.Very characteristic white smoke.
