RRS 3.0 blowing smoke (lots of it)

[GregMilner]

So it seems LRA has finally, after 6 months, given up on fixing the blue oil smoke problem in my 2010 RRS 3.0.

Two replacement secondary turbos, a body-off replacement of a scavenger pump, numerous tweaks, fiddles and six months of head-scratching, and they've finally decided it's all too hard. Simply cannot figure it out.

They're shipping me a brand new engine. Anybody else here had an offer of the same 'solution' for this problem?

It's been a pain in the arse, but I must congratulate the service people at Barbagallo Land Rover on their perseverance. I only hope and trust that the six year warranty I got with the car is extended by two years to cover the new engine.

Hopefully that will finally fix the problem.

If the 3.0 has the same setup as the 2.7 then it may be that there's a problem with the oil return valve that's used to return the oil separated from crankcase ventilation air. The valve is at the back of the block so would be a motor-out job to replace. It could also be a blocked crankcase ventilation outlet in one of the tappet covers, as the left is for partial power use and the right for full power although one would hope that these have already been checked.

Greg,

Is it possible after the 1st issue with the turbo that an amount of oil made its way into the exhaust? Simple but possible..

Rob

[GregMilner]

Yeah I guess all of that is possible. Although I would have thought that if oil had made it's way into the exhaust before the problem was 'fixed', any residual oil would have been blown out well and truly by now. But despite all the 'fixes', the same oil kept getting into the system, getting blown out under sharp load, then dribbling back in again under light driving.

Graeme they did have the whole body off for three days a few weeks ago, so you'd think all of those things would have been checked.

I guess by now LRA have decided to cut their losses - it's probably cheaper to fit a brand new engine and be done with it, rather than more fruitless hours checking this and tweaking that.

[Robocop]

If LR can make a engine/vehicle that allows engine oil to enter the injection harness, then by gravity & capillary action make its way to the ECU & cause a vast array of glitches then allowing oil into an exhaust should be no problem at all..

[Robocop]

What are the chances of not just a dribble but something like a cup or 2 of oil sitting in the first muffler?

[GregMilner]

Probably every chance under the sun. But hell, if the makers of the engine can't figure it out, what chance anybody else. At least they've admitted they're beaten, and they're offering the best solution possible. Can't complain about that.

[GregMilner]

Graeme I 'think' you're talking about the scavenger pump? That's already been replaced with a new one, when they took the body off a few weeks ago.

[Graeme]

It didn't look to me from the diagram in the WSM that the 2.7 has a scavenger pump as its only referred to as a valve and only has crankcase ventilation pipes connected to it. The valve also appears to need the engine separated from the gbox to gain access to it. I understood the 3.0's scavenger pump was for the turbo return oil flow, not crankcase ventilation but that might be incorrect.

[GregMilner]

It probably is for the turbo return oil flow Graeme. I saw the pump when they took it out after removing the body a few weeks ago, it's quite a substantial piece of gear. It looked like a pump and the techies told me it was a pump. Right at the back of the engine, which is why they had to remove the body.

In any case, fitting a new one certainly didn't solve the problem, although it did appear to be faulty when they showed it to me in the workshop.
