Random white smoke?

Condensation in the rear silencer box. Exhaust heats up water turns to steam. Drill a 3mm hole at the lowest point and see how much water drains out. Self tapper in at MOT time. Job done. ;)

Is there any particular smell to the smoke. Unburnt diesel fuel is white. My early One Ten Land Rover used to do it especially on overrun when cold. but given its a more modern vehicle its probably unlikely.

So I have a rover 75 tourer, 80k diesel. On two occasions now it has produced quite a bit of white smoke.

The first time was in December, cold day, start up and at idle white smoke from the exhaust, lasted for 5 minutes and while driving it got quite bad at one point. Then sorted itself out and nothing.

Second time was last week, was jump starting a diesel ZT and at idle same thing, just started smoking, lasted 5 minutes and then stopped.

Does anyone have any idea what this could be? Strange that it is only on these two occasions.

Regards

Jon

When I had my old 75 it used to do this when it was really cold outside. Had 2 injectors reading around 7-8mm3 on the T4. Swapped them and it sorted the issue. So you may have 1 or 2 injectors out of spec potentially.
