It would be useful to know the exact model and age of the car. Presumably a dTi and not the dCi. Need to know.

Probably turbo on the way out - but a guess.

first is it smoke or steam, smoke could be valve seats, if steam, could be leaking head gasket

i think its over fuelling. it should be quite cheap. basically its like the choke on a petrol but too much diesel is being injected to start it when the engine is cold

one glow plug will only go in half way and 2 wont undo would it be easier if the engine was warm
