There is a pipe witch runs from the diesel pump to the turbo which monitors pressure. sometimes a thin membrane in the pump goes releasing diesel straight in to the turbo especially on tick over. eventually that diesel is sucked in to the engine along with all the other gunk where it starts revving up on its own rattleing and banging. i have come across this on lucas diesel pumps before

have the engine code read most auto stores offer this service for free and the code will assist you in correcting your problem ----your problem can be a few different reasons --bad fuel [water]--injector malfunction clogging or flooding--fuel filter--turbo--a sensor --air leak--etc the trouble code will show specifically where to start
This seems to be a symptom of a blown head gasket.
White exhaust smoke is an indication of water / coolant in the exhaust. The car running sluggish and using lots of fuel can be caused by compression loss.
Look at the coolant level color and smell (with cold engine - don't open the high pressure reservoir with engine hot as hot coolant may spray you in the face). If you have a blown gasket, the coolant color may become brownish and it may smell bad or the level will get lower even if you have just refilled the cooling system.
What you can also check for is bubbles in the reservoir. With engine cold, remove the reservoir cap. Start the engine. Try to rev the engine (or have someone do it) and observe if there are bubbles in the reservoir tank. If you see lots of bubbles, you have a blown gasket.
as your old one has blown, when you dismantle it if you find bits of turbo blade missing you will have to take off the head and make sure you have no swarf in the inlets,so if you take it apart and dont dont find bits missing and the engine blows again who are you going to blame......
Hi there, The most common concensus with white smoke is coolant leaking into some where in the combustion chamber as in head gasket, however you have said its not. turbos unless there is massive internal damage usually blow out black/grey sooty smoke. Is there bearing noise in the turbo at all? or Loss of boost? If so it could be early indication of the turbo failing. I would reccomend goign to a mechanic and having a leak down test perfomormed. Sometimes called a compression test. Or you could buy a decent compression tester and check it yourself. IT coudl also mean tha tna oil seal is blown or leaking Check your coolant resivour to see if there is any oil in there and check you oil dipstick to see if it is milky or off colour. Generally if there is either of these two it means that there is some \sort of leak between the two systems Oil and coolant. Anotehr common problem with these engines is a crack or warped head itself. However if your sure its not either of the above it could possibly be water getting into the combustion chamber via the injectors as in dirty fuel, however you would notice knocking and predetonation/ pinging surely. and generally the car woudl be running really rough. Make sure you keep a good eye on the coolant level as if it runs out it will surely kill your turbo friend. Hope this helps you out there, Cheers STeve
trywww.autozone.com to see if they have your car listed for diagrams pictures and step by step instructions if your car is not listed then try your local library they have all the car manuals and even copy them for you
firstly you haven't said hat colour of smoke is coming from rear is it black,white,or a blueish colour secondly have you checked suspension on rear possibilties are worn shox,broken springs,rear suspension bushes or rear drop links hope this is helpful.
