I have a grand voyager 2001 2500 crd they work for the 150,000 km, I have a problem when accelerating out of white smoke from the exhaust.
The machine does not lose speed and the engine is fine, what can 'be? any ideas?

thanks for any replies

I apologize for my English (google translator)

 

White smoke usually points to coolant being burned, i.e. possibly a head gasket leaking between the coolant passage and cylinder bore.
Blueish colored smoke would be oil.
