coolant level hasn't changed, mew injector pump fitted 10 months ago. The white smoke is more of a dirty grey, just like when I blew a turbo on one of my previous cars.
engine noise change was sudden, - if it was water the white smoke would be constant until the engine is up to temperature. Here it is only for about 30 seconds and the amount of white smoke on start up is time dependent, longer between switch off & starting, the more smoke is produced. The blue smoke is definitely oil.
my original thoughts were the wite-ish smoke is the oil pooling in the turbo when it is stood, therefore not burning through the engine just being heated by the exhaust gas, very similar to smoke generator s we used in the army. once that has cleared the blue smoke is the oil leaking from the turbo seals going through the engine & getting burnt.
where on a DXI diesel engine does the master cylinder get it vacuum?
The brake fluid I referred to being burnt was on a petrol, diesels have no manafold pressure so unlikely this is your problem, but fluid loss would be fairly obvious, very obvious with the amount of smoke you mention.
Turbo would probably produce blue smoke with a distinct smell, but take off the hose to iliminate it, if it can't supply it can't send oil into the engine.
What's the odds on the compression being down, it's burning oil perhaps you have blown a piston. If compression low it cant ignite the fuel propely hence the white smoke, unburnt fuel until it warms then it's burning it.
You have no water loss so I would tend to rule that one out.
You changed the injector pump, did you get the injectors checked at the same time, however an overfuelling injector normally gives black smoke.
You sure your timing is ok, sudden engine note change, perhaps timing has gone out, is it due a belt?
Perhaps it's blown the gasket between two cylinders, no water loss but compression issues, but I would have thought you would hear it, or loss of power on road. You sure it's not missfiring or down on one cylinder. take a spanner and slacken off each injector pipe a turn or two at a time and listen to the engine note, make sure you slacken them enough, probably untill they leak fuel slightly, you will hear each cylinder cut out one at a time. Do the same with each.
If one throws up a fault get a compression guage and check the engine compressions.
