HELP? Wrong Turbo???

Injectors dribbling diesel into the combustion chamber instead of a finely metered injected spray will give the black smoke.

When this smoke thing was talked about several months ago, I was sure Jules said the smoke was definitely blue, not black.

I think black or white smoke from the diesel is usually from fuel and blue is from oil.

Jules. The turbo fitted to our diesel’s are a Mitsubishi The one fitted to ours is a normal vane arrangement. The one fitted to the B*W is a variable vane one. Ours is quite reliable. I can not remember how many miles yours has done, but I think it is a low amount. A diesel needs to be driven hard sometimes to bed the rings in. It could be that it has only pussy footed around for most of its mileage. If it has, then the rings will not bed into the cylinder wall, and you therefore get oil past the rings into the combustion chamber. Used to get this on hgv’ S. I used to be given these kind of jobs when drivers only did ‘round the houses’ jobs, and I used to do 400 hard driven miles a day on the motorway/main roads for a week or so. They usually did not burn oil when I handed them back.
Just a suggestion to you to give it a few longhard runs. Use the gears upto 3500/4000 rpm. It will do it good.Forgive me if I am wrong, but I don’t think you rev it enough.

As I keep saying it does not burn oil once warmed up, only on intitial start up

I give it 2000 revs at a stand still fort wo or three minutes then the smoke begins to clear once on the road no smoke in the mirror. I have taken it out on quite few long runs and not exactly hanging around, she is quite responsive on pick up.

Had similar smoking on my Freelander with as good as the same engine, and it was an injector issue.

Luckily a bottle of Forte cleaned them out.
