Trying to sort out the reasons for my Escort 1.8TD smoking pretty bad.
The car is a 95 1.8TD with 74K miles which appears genuine.
The smoke is dark/black so its a fuel problem.
I change the oil/filter every 4K miles and the oil level hardly moves and so far have never had to top it up between changes so its not an oil problem.
The darker nights now allows me to see "exactly" when it smokes, as I use the person's headlights behind me to experiment!
Its not because of hard acceleration or anything like that, and I definately do not have a power loss problem, the car drives ok.
When the engine is cold - its not as bad.
Flat road, normal cruise speed.......give the throttle a quick press down or squeeze = loads of smoke out the back. Slam the pedal down, again loads of smoke out the back.
It would appear that when the extra fuel is put through the system, the engine cant cope with it and chucks it out the back and keeps chucking it out the back until the speed has increased enough to handle it. This scenario can be repeated all the way up the speedometer range.
Is there a fuel pump issue here? maybe injectors have faulty pressure springs inside them? or maybe the fuel return system is not working correctly? Shouldnt this unwanted/unused fuel be returned somehow instead of being chucked out the exhaust?
I have tried everything on this problem, new filters all round, new oil, injector cleaning additives, checking valve clearances, different diesel from different garages etc..
The car is fitted with Lucas pump/injectors - are they troublesome?

If its not a bunged up air filter then almost certainly a pump prob,NOT a DIY job. If you are within 50 miles of the Brighton area,worth a trip to AutoMarine Diesels in Hove. Sorry , dont have number to hand at present

Have you got a boost gauge? I would check what pressure the turbo is boosting to. Its possible that it isnt producing as much pressure as it used to so thats why it is over fueling. A simple twist of the wastegate can sometimes resolve this. You could of course turn the fuel dow yourself and see if that resolves it. Has the car always smoked or has it just started recently? I can send you a guide to the fuel pump and turbo if you require it.

Itchy - do you need an e-mail address to forward the fuel pump guide.
I'm planning to get the timing belt changed soon - this will ensure the timing is okay.
I have noticed the head is new so there must have been some problem there recently.
I have only owned the car for 6 months so I've no idea how long its been smoking.
Also its the first Ford TD so I'm still learning.

I spent 11 years working for Lucas assembling and testing injectors. Mostly for ford 1.8TD.
These injectors do not give many problems but one thing that happens is that fine dirt gets between the needle and nozzle body.The nozzle then stops spraying and just squirts fuel. Also the needle may not seal against the nozzle body between injections. This causes fuel to leak into the cylinder ( wet seat ). None of theses problems are likely to cause lack of power unless really bad.
The life expectancy of this type of injector varies but should be checked about 60k so this may be your problem. A diesel company should be able to recondition your injectors for about £20 - 30 each.

you could try looking at the turbo vacumn hose, as my brother in law a smiliar problem, it smoked mostly in 2nd. found out the the turbo vacumn hose had a split in it. now replaced the car drives like new - no longer smokes.

If your vehicle is fitted with EGR(exhaust gas recirculation-many were)remove the vacuum pipe from the valve and block the end of the pipe but you will see smoke in the dark (in lights)that you would not see in daylight.

Itchy - any luck with that pump manual?
I have been told to replace the CVT Valve - its part of the emission control system - no idea what it does though!!!!!
