Can anyone help out. I have changed the Glow Plugs and still i have white smoke when idle or first started. When i am travelling along the road not a problem. I also sense that there is a bit of loss of power until i get on my way.
if anyone can help please do.
i also have this problem,
i also have this problem, first start of the day long turning then when started no power. A friend said to cut out the ignition rely that controlls th eheater plugs and use a manual push button instead as the ignition only heats the plugs for 5 secs and it clearly needs longer. This dose work but still takes a bit to start it and i wont use easy start!!!! loads of white smoke, darnt start in a shed then once running put my foot to the floor and nothing dosnt go over 2000 rpm. once the engine has run for a min then its fine and dandy. Its only a field car but annoying when towing tracotrs and other hevy objects its a pain in the arse lol
any help much apricialted
thanks henry
my 2.8 tdi is the same on
my 2.8 tdi is the same on cold morns, soon clears and runs fine, no water loss, i use the heater plugs twice before starting it
White Smoke
The answer to your question is simple, it is water entering your engine, this produces the white smoke; this is due to the time of year. Damp conditions mean condensation is formed on the inside of engine components, and ancillary components such as air inlet pipes and intercoolers, also damp air is being drawn into the engine, particularly when it is foggy.
Condensation and damp air reduce the efficiency of glow plugs by cooling them when the first start occurs, when the engine warms it dries the engine, and its ancillary's out, this leaves only damp air to contend with. Worst affected are vehicles standing outside when a warm engine cools overnight, and it is frosty, when the engine is sufficiently warm, the heat produced by the turbocharger is hot enough to dry the incoming air, this eliminates the problem of white smoke.
Vehicles which may be little used, such as those used only at weekends, or only a couple of times a week, predominantly for short journeys suffer the most.

I agree entirely with these comments but it is also due to hot gases meeting cold external air and instantly condensating.
For those using the car for short trips the silencer/exhaust life will be shortened by the amount of water remaining in the system after a short run. It is the same for those storing over winter, if you start the engine run it up to normal working temperature to dry out the system or the silencers will rot out quicker.

white smoke
hi
Thanks for your comments. I am losing lots of water from the rad and it doesnt matter if i have done a long trip or not. I use the truck all the time. I have heard it could be the injectors. I have also heard this is a common problem with tracks.
I realise this time of year you will get a lot of smoke behind vehicles, but not to the point of pea soup behind you. Very embarrassing when filling up at a petrol station.
Do you think i have anything to worry about. i have spent heaps on this vehicle and really need a break from paying out on it.
I have also been told it is the cold start, but i have to say that means nothing to me!! What would i be looking for if it was the cold start.
thanks

about the cold start. A
about the cold start. A friend who works on busses told me that my plugs wernt staying on long enough. To c if the plugs need longer u need to people. One person in the cab ready for the turn and another person. The other person takes a wire from the + terminal and puts it across the long strip of metal that connects the 4 plugs together. Touch it and hold it for 20 secs with ignition on. This will give your plugs longer to heat, like heating a tracotr manualy. give it 20 secs and turn it over. before i used this method mine would turn for 30-40 secs then start but now its done it on the 3rd -5th turn!
thanks henry

Losing water and pea soup out the exhaust really points to water entering the combustion chambers and being blown out the back as steam. I would support the theory of the head gasket. If you wern't losing the water then perhaps the other ideas would be valid but the water loss is the give away.

are you sure the cylinder head is ok
take the oil filler cap off and look for emulsified water, this will be alot of scum around the cap,
the lack of power is a typical diesel problem however if you have a blown cylinder head you will get pinking (lack of power)
have the cylinder head pressure tested asap as you might get away with just gaskets, if you need a head its hellish expensive and the truck will never be the same again, its funny but i had a head blow and the truck was under powered from the day it had the new head, also friends have agreed
