Uno Turbo squirts. ASSISTANCE!!!

Hello Fiat friends, have a problem with my Fiat Uno Turbo 1.3 BJ 91. Ask for help and thank you for your efforts in advance. For some time now the Uno has been smoking quite out of the exhaust and smells quite unpleasant. When I go to work in the morning, everything is ok, then there is no smoke. As soon as the car comes to temperature after some KM the thing looks different again. As soon as I stand at the traffic light then it starts to smoke after a few seconds n, if I then drive again, then everything is ok. Even during the ride, when I drive without charging pressure no visible smokes. However, when I give gas and then change the gears, a strong smoke cloud comes out of the exhaust in the time and the backman certainly does not see anything more. Then it settles again until the next load change. A colleague said that the turbocharger is defective, but nevertheless builds up properly charging pressure, but sometimes more times less. (sometimes 2-3 tent el difference) Charging pressure is about 1 bar, have bought the car like this, with the charging pressure, but also seems strange to me, because the pressure should be about 0.6, I mean at least. Should the loader actually be over, what else do I have for alternative ones, because a used 1.3 he turbocharger is very difficult to find!? Do other turbochargers from other Fiat models also fit, without now great conversion something? Maybe also something with a little more Le istung?, but doesn’t have to be, would only be happy if the car still brings me good to work and of course also back again. Dabke again for your help, knows really nict where else I could turn 🙂
