Hi,
The blue smoke got worse, enveloping the car during start up. This improved over time as the engine warmed, but the smell of oil/diesel remained.
The main dealer recommended and fitted a new turbo charger and then new injectors. But the smoke persisted.
So, I took it to a small local garage for diagnosis, rather than part replacement. They listened and then adjusted the timing belt, (which had also been replaced by the main dealer).
The result is that the smoke seems to have reduced substantially, except for a little amount when the engine is started....
