I've become increasingly paranoid about the large puff of blue smoke from the exhaust pipes caused by oil pooling in the secondary turbo on my 2010 D4. This 2nd turbo only kicks in at about 2800 rpm, so after a long motorway trip there can be quite a bit of oil in there, creating a fairly spectacular cloud for the vehicles behind!
LTB00487 is Land Rover's solution to the problem, which involves fitting a shorter oil return pipe from the turbo that drains directly into the block, rather than lower down in the sump where the original pipe goes to.

1st step was to disconnect the turbo bypass valve from the bottom of the intercooler, allowing any oil to drain out of the intercooler...

Despite having 112000 miles on the clock I was quite surprised at the amount of oil and water (condensation) that drained out of the intercooler....

I also decided to run some paraffin through the intercooler from the top, which cleared out some more of the sludge, blowing through with a hair drier to dry it out on completion.
Next task is to remove the starter motor, which gives access to the port on the side of the block that the new pipe feeds into. The layout underneath a D4 must be different to a D3, as I'd read a few threads on here about how difficult the D3 Starter is to remove, but with a bit of trial and error this one came out fairly easily...

With the starter motor out of the way you can now get at the bottom of the turbo and also the port on the side of the block (seen here with the blank still fitted, secured by 1 bolt)...

Whilst I was underneath I decided to remove and check the turbo bypass valve as some people have had problems with it sticking. No problems with mine though, it's been very well lubricated from within!

I won't tempt fate by commenting on how successful the modification has been just yet, but initial impressions are positive! With a few more miles of motorway and urban driving, time will tell. The shorter pipe length and drain into the block above the oil level certainly should allow the oil to drain out of the turbo faster than it did before, so fingers crossed. I believe all vehicles after VIN DA676456 were fitted with the shorter pipe as standard, so this only applies to earlier D4s (date tbc).Discovery 5 tdv6 HSE Corris Gray Outback Engineering Limited Edition IID Pro MV License

Does anyone have the part numbers for the pipe, blank and gaskets please?
Hi cd.strydom
I carried out this mod a couple of months ago and it has been 100% successful
Some of the part numbers seem to have been superceded from the original post. So, just to clarify the parts you need are:
Despite being a TSB it is chargeable and I've recently had a Dealer quote of £325 inc VAT to have it done, so I'm going to look into getting the parts and doing it myself following this guide and the TSB destructions LRs are a fond memory, apart from the maintenance.

Rich, I think it must be oil. I haven't had to put in a drop of oil since new; the early D3 blocks soaked up oil faster than I can produce it!
My D3 dosn't soak up oil, possibly 0.5 ltr between annual services.It can when others can't,
It will when others won't,
It goes where others don't.

The parts come to about £90 in vat, and looks to be 1.2 hours labour- although that'll be for a main dealer with knowledge of the vehicle, a ramp, and the right tools- so maybe 2 hours labour?
I'm going to buy the bits and get my local spanner man to do it for me.
It's getting tiresome trying to find an old bus or knackered taxi to accelerate in front of when I get on to the by-pass (so they get the blame for the ridiculous amount of smoke lol)

Same issue with my TD3.0 245 hp
Hi guys,
I've just fund this amazing forum and it seems address my issue with my RR Sport 3.0 2010 245 hp (180 kw). After an acceleration the exhaust smokes white/light blue, even when the car stops at the traffic light.
My LR dealer told me that the 2010 models already fixed the issue with the pipe and also my car has the upgraded connection. So my question is how is it possible that I've already have the same issue even with the turbo upgraded? how can I check if my LR dealer is right?
thanks friends

On the LTB00487 is wrote:

Is your VIN included in the range?
I really don't think the 2010 engines has up to date pipe !!!

Thanks for the reply
Yes my VIN falls between the VIN range but my LR dealer told me that the pipe has been updated when he changed the engine and the 2 turbo of my LR32. Now the question is: is it easy to check if the update is really been made? if it is updated, what could be the problem to my baby?

Yes, from the LH front wheel.
you will see the turbo oil discharge. New type is connected to the block (cast iron, brown color as rust), old type to the oil sump (aluminium)Discovery 5 tdv6 HSE Corris Gray Outback Engineering Limited Edition IID Pro MV License
