Black smoke is an indication the the engine is being starved of air. Check the air filter first, if that is clean you could have an obstruction somewhere in the inlet trunking. Try disconnecting the air intake pipe from the manifold, if it runs better the problem will be in the intake.

From the amount of black smoke you describe, it sounds like it could be some sort of enriching for cold start has jammed in at full whack, if Peter N's sensible checks reveal nothing it might be worth getting codes read.

If the turbo has seized or otherwise then overfuelling might also result, together with obvious power loss.

If No2 injector is leaking from the nozle that will probably be causing your black smoke.

All injectors leak back to some extent, but if the leakage is too great you will loose fuel rail pressure which, if bad enough, will cause a no start condition.

I would have thought the diesel testing place you used would have been able to advise if the injectors were usable or needed replacing.

Leaking injectors will kill your engine if left too long, the diesel will strip bores of all lubricant

If you disconnect the air intake from the manifold and rev the engine you should be able to feel the draught from the end of the pipe.

First thing I would have checked is the EGR valve, could well be coked up and jammed open.

For a diesel engine to run away it has had to have been overfueled.

That fuel can be either diesel or its own engine oil.

Turbo's do fail,& if they pass too much oil past their bearing on the inlet side, effectively fuel the engine from its own oil.

I would suspect that is most likely what has happened.

The engine will almost certainly be ruined now due to overevving. If it was caused by the turbo which you supplied, I can't see there being any blame for the garage.

yes theres defo blame fo the gaage as they never cleaned the intercooler or exhaust out first and they have let it run on its own oil and thats why its revved on its own and blew the engine dont forget the car started and was ticking over fine when it was left in there hands and all it wanted was a turbo being fitted they should have known how to do the rest not tryn give it back to me as a none runner no compression blown engine the garage is liable as its in there hands and care etc
