If it does short journeys then it will be steam in the exhaust burning off.
If it was something serious like a head gasket then it would happen all the time

When the car is warm, is there any heat come out the blowers?
Does the temp. guage sit higher than normal?
Also you can check the oil filler cap or water expansion bottle for signs of water mixing with oil (mayoniase).
These would suggest head gasket problems.

But is it smoke or steam? As Bailes says it could just be water lying in the exhaust.

Best of luck!

Theres your problem. Your doing more damage to your car by starting it up and not driving it.
The car has to be driven to keep the engine from getting full of soot.
When you set fire to something you get water, this water sits in the exhaust and when the engine gets hot it's slowly burning it off.
Stop turning the car on for the time being, change the oil and when you pass your test take it for a good run down the motorway!
