Ah yes DrRob excellent searching which says:

Quote:

There is a green 2 lipped rubber seal further into the pipe that slides over the throttle body to make the seal. The clip is basically to hold it in place. You can't buy the seal separately though. I know because my pipe felt loose and had a bit of oily residue at the connection. It's got the full force of the turbo blowing through it and I think it could have been designed better. Cheers Kev.

Gents,
Please feel free to ridicule this idea, ...
Halfords sell self amalgaming rubber tape.
If you remove the pipe and thoroughly clean the end of the throttle body and the pipe end., refit , then wrap a couple of layers of tape over it, you should have a pretty good airtight seal.

Nothing wrong with that Mike, same as PTFE.
Self Amalg. may be a bit more secure when sliding back over the throttle body - once cured.

Self amalg. tape is great when cured, bit of a phaff to keep in place until cured. I think either will do the job.

A new pipe, clip and seal is nearly £400 IIRC so nothing wrong with a DIY fix!
Especially on a bank holiday weekend - nothing to loose!

Cheers guys
Does any body know what you would call this fitting (the plastic one with the clip)?
I think that I will order a new one to be on the safe side.
I thought that there would be a seal of some kind, As the clip only stops the fitting from sliding back and forth, it doesn’t actually clamp it, shame it’s doesn’t come separately

GGDR Quote: "I did a low pressure smoke test which revealed nothing.

What was interesting was the boost pressure this system is under is clearly much more than a standard smoke test can generate. In the diagram I posted up a bit, (whilst not any kind of scale) the primary turbo on the left has much thicker blue lines so I guess that on is a beefy turbo. I love feeling the boost come in from as low as 1000rpm. When the secondary kicks in too, the total boost pressure must be really quite high. And that is why these hoses and joint can fail. I believe there are professional high pressure smoke test machines which I'd suggest you try to have done if this doesn't crack it."

Just to back this up, it needs to be a HI pressure smoke test. Mine revealed nothing under a Normal test but a very small amount under hi pressure smoke test. this is because the cracks can be so small but make a huge difference to the "pull" capability.

Dolphin -

You can get a part no using microcat.

Or ask for the intercooler to throttle body pipe

Inside the plastic pipe connecting to the throttle body is a seal. I gently removed mine and cleaned it carefully before putting it back. it has a clearly defined lip that is supposed to create an air tight seal, although I'm not convinced it's up to job after a number of years under the bonnet with the temperature extremes it has to cope with. My pipe also has a lot of movement, at least more than I would expect, even with a good fitting clip. Ideally a new seal would be available but my understanding is that you cannot buy these separately. As already mentioned I would clean the whole area and look for any oil residue that is showing. Ideally you'll need to ask around a few garages to see who could carry out the high pressure smoke test as this will confirm if you have a leak and where it is. 2011 TDV8 Vogue SE

How are you getting on with yours, we had very similar faults?
Steve

Hi Steve, I haven't been able to use it much since the lockdown. I took it for a 70 mile run 2 weeks ago and had no issues apart from the plume of smoke when I put my foot down but this would be the 2nd turbo oil issue (well documented). I am out in it again on another 70 mile round trip today (work purposes) so will report back later as to how it went. I would recommend cleaning the seal inside the plastic pipe that connects to the throttle body, just take a note of how it sits in the recess before you remove it as it has a prominent lip that appears to me to only be effective if fitted correctly. I still find the amount of free play in this to be more than I would like but it seems that this is the way it's been designed to fit. Prior to removing and cleaning I did have a slight misting of oil in this area so that may have a bearing on the issue I'm having currently. Problem for me is that whenever I venture out I'm always concerned about if the plume of smoke is going to suddenly appear again so it spoils what should should be an enjoyable driving experience. I did read an article about the 2nd turbo expelling excess oil automatically if the level reaches a certain level, meaning that the oil would be burnt off as it entered the exhaust system, however, I am unable to find the article again so not sure whether it's accurate or not. Leaves me wondering if it's worth going for the turbo drain modification, although if that doesn't improve things it's a lot of money wasted. 2011 TDV8 Vogue SE

Dennij - keep us posted! It's advisable to boot the motor (when warm) to prevent the oil pooling in the 2nd turbo. They appreciate their taps being opened up regularly
I wonder if that seal inside the pipe could be sourced separately from somewhere???  2011 4.4 TDV8 Vogue SE Buckingham Blue with Ivory and clear glass = "Rory"

dennij,
If it helps, here is my smoke experience.
B.B. was a really bad smoker, probably because I do a fair number of short local, stop start driving, but every time I hit the open road and put my foot down I got an embarrassing amount of blue smoke.
I was lucky to get the mod done under warranty by the supplying MD, but since completion I have never had a hint of smoke and every year it reads zero on the MOT emissions test.

Hi Mike, as you say, the plume of smoke is embarrassing, last time I had to open the taps was to pass a couple of cyclists who became engulfed in the cloud I was leaving behind, hardly a good advert for us folks that drive around in these cars. It does clear if I have to boot it again but I'm at that stage where I'm happy to just waft around rather than chase the 0 - 60 MPH times. Interesting to read your comments after having had the turbo drain mod carried out, it's one of the reasons I've added it to my to do list if other remedies fail to resolve my issue. Just need to get my indy to open and clear his backlog of jobs so I can book in for a high pressure smoke leak test, assuming he can do it of course. 2011 TDV8 Vogue SE

Hi dennij
After what happened in my original post, I had the 4 short hoses changed, and everything cleaned up inside the plenum, and new oil and filter. But they had to force a regeneration, this brought the level down to 2g, but was on 6g by the time I connected the iid tool.
The car has always driven perfectly, even with the warning light on, never had restricted performance as yet.
Same as you, I used to get a plume of smoke every now and again when I floored it, but It was intermittent.
Since having it back I have not had any smoke at all, but probably because I have been trying to drive it further and quicker than normal.
My main reason for this was because I was monitoring the soot level, and it seemed to be rising very quickly, I was worried that it would not regenerate, and I’d be back to where I started, I took it for a drive to the nearest autoroute, and set the cruise at 75mph, and it did a regeneration from 17.5g too 4.2g, would probably gone lower, but I had to stop at a toll.
Being very relieved that it had done a regeneration, I returned home approx 60miles of mixed driving, by the time I got back it was at 9g again!
I did not remove the inter cooler hose and fitting, although there is oil around the base of the connection, mainly because I’m worried of breaking something, and apart from the ptfe tape idea, which I thought would be very awkward to apply without removing the throttle body, did not think that it would improve the joint, in fact could make it worse.
I spoke with my garage guy, who I do think knows what he is talking about, and explained as best I could about the quick rise in soot level, he in turn said that this was quite normal, and not to worry about it, but try to go further in the car.
I have never monitored the level before all of this, and have no idea whether it is producing more, or less than it was before.
As I said car is running lovely, goes like stink, and no smoke, I have probably covered 450miles since I got it back
I am still not confident that it is all ok, but will see what happens.
I still wonder why I had that huge plume off smoke when the warning came up, I thought it had blown something, it was that bad.
Will keep you informed.

Steve
