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

I changed the turbo now white smoke coming out of my exhaust

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.

Car running rought when u press the throtle there is a nocking noise i think this is the nock senser if i take the ht leads off the spark plugs 1 at a time starting from left they all make a nocking noise...

If you're getting ticking-type knock, I'd first look to the lifters. if it's a real hard knocking, it could be your main bearings on the lower end

If i have a bit of experience with cars could i fit a turbo to my mondeo zetec tddi y reg. my current turbo has blown

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......

Smoke from exhaust

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,
