Cold start today

Morning peeople.

i started the beast this morning, 2000 2.5DSE, with the following:

- ignition on, as soon as light flickers off crank.

It cranked for 10secs or so, but sounded like it was trying to fire, to be honest sounded like a petrol starting after a carb rebuild.

Finally fired, smoothly started, but i noticed white smoke come out.... Coming from a largely petrol back ground, isnt white smoke rather a bad thing??

To confirm, fuel tank has over £40 worth of diesel in it and was showing just under half full on gauge.

Heeeeeeeeeeeelp......

White smoke is probably just a bit of condensation, did it clear quite quickly? Check your leak off pipes between injectors

It was a small cloud when the engine finally fired into life.

Once it was running, it was absolutely clean.

Condensation in exhaust, mine usually gives a puff of black smoke,

Could you confirm or re-educate me.

Black smoke = over fuelling

white smoke = fuel starvation (from cold)

black smoke is fuel burning with not enough air (excess fuel or restricted air),white smoke is water vapour if dissapates straight from exhaust ,or unburnt fuel if smells and lingers

It definately smelt of diesel and did not instantly dissipate,

Black smoke is overfueling, white smoke from cold start will just be condensation, you can get white smoke from injector pump timing being out, but you would constantly have it , it wouldn't clear

Bad start and smelly white smoke = duff glow plugs on a couple of cylinders

Lose one more and it will not start at all.
