1999XDI 5door - engine noise changed suddenly yesterday.
Cold start this morning - big cloud of white-ish smoke from exhaust.
settled down to a blue smoke on acceleration once warm.
White smoke reappears on starting when the car is stood still for a while, then back to blue smoke while running.
Oil level has dropped slightly.
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.
