I have a Nissan 4.2 TD and every time I take it to cold climates (I live on the Sunshine Coast) I have trouble when starting. It blows clouds of unburnt fuel and chugs and ph-arts around for some time.
I've had the problem siince new and Nissan do not seem to know what to do about it.
The preigniters have been tested, the compression is OK and the injector pump has been overhauled. It has had a stage 2 power up, with bigger compressor and the pump rerigged. Nothing seems to have worked thus far.
Does anybody have similar problems or, hopefully a cure for this embarrasing malady??

What grade of oil are you using?
We had a similiar issue with a Nissan diesel engine many years ago, before we had switched every vehicle to synthetic. Once we changed the oil on
Mobil's recomendation, we had no more problems.
At the same time, we had a Diahatsu Delta gearbox that would not cooperate till it got warm. The gearbox tolerances were small, and would not allow the syncro gears to speed up sufficiently.
Mobil also advised the correct grade synthetic oil for that and end of problems.
