Hi. I keep getting blue smoke in first and second gear when pulling out of a junction etc. And Sometimes when i start the engine. Its seams to stop when everything is up to temperature and runs as normal (or so it seems) any ideas what this could be??

sorry to be the bearer of what might be bad news but in my humble opinion blue smoke is not a good sign.
Tell us more about the car - age, mileage, petrol/diesel - someone with more detailed knowledge will be along soon.
Blue smoke from a car exhaust is generally a bad sign, and the cause of it will need to be investigated/repaired as soon as possible. It’s either a problem to do with the oil, or internal engine components.
In petrol cars, it might suggest that oil is leaking into the engine block where the fuel is mixed with air, while in diesel cars it may simply suggest that there is too much oil in the engine.
In the worst cases, the cylinder heads, pistons or valves might all be worn down.
Regardless, you’ll want to get your car looked at by a reputable garage if it’s emitting blue smoke.
