Default White smoke at start up?

White smoke comes out from the tailpipe when starting up cold. I'm suspecting some kind of leak. I sorta want to keep this car, but at the same time keep driving it for school. Should I be worried about the white smoke?

sounds like an oil control ring problem. when they start to go it will only be on cold/first starts that they smoke, but i've run motors for a year+ without it getting much worse.

try some lucasoil oil stabilizer on your next change. does wonders for me.

White smoke would more likely be caused by a coolant leak. Probably the two O-rings between the intake manifold and the motor.

It smells like...gasoline...

I also didn't mention this only happened after I recently did an oil change. And the car has a straight pipe welded on.

Make sure that your oil level is not too high. This will force oil into the combustion parts, and can also blow out your oil control rings...

Never really had a trouble starting up my car, though I always have to open throttle twice before starting the car.
