New pics - body off RRS 3.0 for major surgery (blue oil smoke issue)

[hydeslane]

I have a 3lt D4 and guess what - it blows smoke under hard acceleration when the second turbo kicks in. From my observation of other RRS and D4's it seems that they all blow smoke. The question is - how much smoke blowing is normal? I've had mine checked by the dealer and the report - car is normal. So how does one know if you have a problem.

What colour is the smoke? Black is unburnt fuel.

If it's clouds of blue/white smoke, then you have a problem - it's oil, and it shouldn't be burning. Yes, all diesels emit a little black (fuel) smoke under heavy load, and it is normal. My boat does it, my car does it, and it's rarely a worry.

But my car has been blowing blue smoke - lots of it - intermittently under sharp acceleration. And that's been a problem.

Graeme, I can't say if mine continued to blow smoke AFTER the second turbo kicked in, but it certainly would start blowing smoke at about 2,500 to 2,800 revs. Not if the rate of acceleration was reasonably gentle, only if I gave it a shove.

Thanks Greg. From yr advise I'd suggest what I'm getting is black & probably normal. Hard to tell in the mirror though. I've viewed the vid from the other thread and mine is not doing that. The street almost disappears. Perhaps it's a case of - if you have a problem, you'll know it. Thanks for sharing with us. Also loved the posts from yr trip a while back.

If its oil smoke you'd know...my rear visionin the mirror was being completely obscured by clouds of it. Picked the car up this afternoon...amazing how they can take it apart, replace the part and put the whole thing back together again in a couple of days...and gave it a fang up a steep hill. No smoke. Fingers crossed its fixed.
