did a quick search found this,


White smoke from a diesel engine could be normal when it is very humid and cold, the engine is cold, the glow plugs are not working to their full potential as long as the white smoke is not excessive. It also could be an indication of a head gasket sealing problem. Most will not leak after running a while, due to extreme cylinder pressure. After the engine rests with combustion pressure in the coolant system, the coolant can work it's way back into the cylinders through the failing gasket sealing surface. If this happens and causes a hydro lock condition. Combine that with a high torque diesel starter and you may need a rebuild or possibly a new engine assembly. So make sure that your coolant level is full, and is not dark in color or smells like diesel exhaust (smells like a weird spice in the coolant, almost like someone put black pepper. this was a direct quote from wicki answers.com, so please dont think i am trying to be clever or somthing! a diesel garage would no doubt find the problem, but could be pricey, see if you get them to locate fault then do it yourself, sorry cant be more helpfull, ive never had this type of fault myself, so have no experience of this particular problem, do a google search like i did, there is loads of stuff there, if you can find out what its not then you maybe a bit closer to finding out what the problem is, good luck, regards, geoff
