a lot of smoke when starting cold

Hello, I have a Peugeot Expert 1.9TD 92CV that when starting in cold made a lot of smoke and the engine does not rotate round goes to trompicones, something curious that I have noticed is that being in a place that I usually go to more than 1000 meters high, it still starts worse and more smoke still, as you walk and take temperature the engine is already well, then it is very good, then it is very good, then it is very good.

thank you so much

Hello,
the first thing you should do is check the heaters, it is easy for some to be molten.
All the best

Verify seals in valves, it may be that oil through the valve stamps on the head, greetings

It can be injection pump problem or injectors

Hi, it starts with the easiest, new air filter and new heaters see if it improves
greetings
