My only left solution, it will be to open the entire engine, and see if something it is broken in it, but I thnik I will do that on the autumn...

To check for oil leak, you might do a less intruding analysis with an endoscope (small camera with a light in it on a flexible stick) to look inside the chambers when the engine is cold and has not run for a while.
Current "fleet":

From my experience your problem appears to be a classic glow plug fault or an injector issue.

The injectors you fitted were second hand, how do you know they are working perfectly?

Hi jasper5 and sorry for this late response,


Yes, the injectors were second hand, but before putting them on the car, they we're tested on a special bench... I actually had tested 7 in order get 3 fully functional... most of them had values to high on the backflow circuit.

And I also replaced the glow plugs, and the glow plugs realy. What I can tell for sure, is that if I disconnect the coolant temp sensor, car starts almost good but still with a huge cloud of smoke.
