Hello all, thx again for your help!
Turbo fins ok, and no debris etc.
"Check the crankcase cyclone breather on the side of the engine - mine has stopped working which is resulting it opil being pulled into the turbo, so when you rev it from cold, it pulls this settled oil in in a 'lump' an you get blue smoke. Then, when its warm, the oil is vapourised so you can't see any smoke.
Take this breather off, and look at how oily it is where it joins the air intake. "
There's some oil in the pipe, also in the breather pipe attached to the valve cover, and you say, you do get a lump/s in the blue smoke. What's the remedy? New cyclone breather?
"There is always a little oil wandering around turbo diesels, and it eventually reaches a cylinder.
If the car is going fine, not using oil, running with clean exhaust on a 70 mph cruise, then stop worrying. Loads of Landyzoners are wishing right now their Landies could do that!"
It does all that, sorry, just a worrier by nature, many thanks again.

HI
How do you know if the cyclone isn't working?
cheers

they dont fail unless obviously broken ,
no but they do gunk up and deposit more oil in the inlet than they should.
they only cost about £7, pop a new one in if you suspect it.
Reasons to suspect? oil in the manifold between the air filter and the turbo. Some oil is normal, its kinda hard to work out what too much it.
Oh, and they have a diaphragm inside them which *can* (not very often) split. So they can fail without being 'broken' externally.

That is simply not correct.
However, there is no point in arguing with such an expert.
Are you sure its not just the cold? When I start mine from cold I get a cloud of blue/white smoke which persists when you rev it, drive down the road and as it warms up it vanishes. Only does it on cold days and only when the engine is cold.
I dont use oil or have loss of power and when its warmed up no smoke at all even on hard acceleration.

I would be interested to know how long your glow plugs have been in there, and what would happen if you were to fit a set of top quality new ones.
Smoke on cold start is usually due to poor ignition and combustion, because the heat of compression is being reduced in the cold engine.
I should imagine since the day the engine was built! I have never had them out!! Mind you, I don't give it much glow on start anyway!!
My thinking as well!
But one cold morning, why not give it a full time GLOW, and see if that reduces the smoke?
