no i know exactly what you are saying though, i start it, after about 2 seconds the blue smoke comes out, for about 10 seconds which by then steam has also started coming out, but u can tell the difference in the colour.

Well to be honest the car never ever smoked before, but the turbo was second hand, and i had the head off so i thought i may aswell re-build it as chances were it would of gone soon.

All it does literally is this tiny smoke when it starts and no other time.

The only other thing is ive changed oil since putting the head back on.

Before it had comma 5w40 for the initial 3.5k, i thought it deserved a change, and now im using Mobil 1 10w40 as my mate works for Renault and gets it me free (cheers dan), thats the only other thing that comes to mind is perhaps its the different although i cant see that would make a difference. Although slightly thicker..?
