Hi all
Did the turbo additive
Can I ask what lube people recommend for the turbo arm and how to get it in the right place please?
As last time I used a spray but couldn’t see where it was going!
Cheers
And I think you’re right! There’s been two times now where the turbo didn’t quite kick in. Must be the armDisco 3 SE Manual 2005 V6 2.7

I'd wait to see the effects of the additive first, or have you used the tank up ?

I wouldn't spray anything on the turbo they normally stick internally, just work the rod back and forth and use the cleaner additiveAndrew

I use a good quality injector clean every 3 months in a third of a tank of fuel and run it until the light comes.
As my thinking is if the injector are good they won't cause the soot and oxides that cause the turbo to stick.Andrew

Hi all
Updating on this..
I did a bottle of expensive turbo cleaner - brand beginning with an F but unsure now
And just now have had a go of moving the turbo arm with a piece of metal bent in to a tool
But the turbo actuator seems quite stiff even with 15 minutes of moving forwards and backwards
I’m wondering if now is a good time to spray something on the arm?
If so what?
I used wd40 and copper grease spray ages ago. Obviously both transpired to be useless!
Wondering if there’s anything anyone uses - also how on earth do I see / control the spray to get on the arm blind? Please and thanksDisco 3 SE Manual 2005 V6 2.7

I use Dipetane and buy it in 5lt jars. I have used it for years on my own car and for customers (with questionable emissions for MOT) with never a failure!!
I can only say that when I removed my own turbo after 11 years the vanes were almost spotless!
I have no affiliation to this product but I can say with absolute confidence that it has worked for me on many occasion's and continues to do so.
As for the actuator I use a mixture of copper grease and a small drop of engine oil (to thin it a bit) To get it into the arm I use a long artists brush to load it into the cups whilst then moving the arm to work it in.
It sounds like it might be your vanes that are stuck, and if so it will take time for an additive to burn off the crud. In the meantime you could try the above method on the arm and see if it helps! It is fiddly and awkward to get at it, but you need to be patient and take your time.
If you can get the copper grease and oil to the consistency of say honey it will be enough to get into the cups and stay in there!yµ (idµ - eAµ) ψ=mψ

Hi I don’t understand what the cups are?
By brush do you mean access it through the top ball from the front wheel arch behind the heat shield... soak the brush and then dab the brush on the arm ball that can be seen and let the oil drip all over it and it would run it’s self down the arm with gravity?
Or are people accessing from a better point?
I did a bottle of turbo cleaner
My current problem is in first gear the turbo doesn’t kick in unless I put my foot down. First gear seems to drag. I’m presuming this is the turbo?Disco 3 SE Manual 2005 V6 2.7

Yeah it's a ball and cup linkage! If you are not getting a fault code for the actuator or for boost control then it must be working reasonably OK I would have thought. Even so, it is a good idea to lubricate it anyway.
Access is as you say with the heat shields removed, then use the brush to load/push the mixture as best
you can into the cup/ball. You need to try push it into the cup otherwise it's a waste of time. Then move the linkage to work it into the joint.
The copper grease is too thick on it's own, so you need to mix it up with the oil until you have it a bit thinner. Not too thin though or it will just drain out.yµ (idµ - eAµ) ψ=mψ

Could you think of anything else that would cause first gear no not boost all the time?
I noticed after towing there was a lot of black smoke puffing out exhaust for a day after. And first gear seemed/seems to drag down in speed when I take my foot off the accelerator. Unlike all the other gears that just roll off the accelerator. Is the best way to describe the issue I noticed. And then I tried boosting it and again in 1st gear only.. the boost didnt seem to kick in every time. Seemed to drag up the revs instead of other gears that boost at 2000 revs.
I was thinking towing strain and sticking turbo may have caused it to stick a bit in first gear or carbon build up somewhere along the line maybe in slow speed causes it to strain. Or maybe I’m over thinking how it drives.
I was going to ask... should I first clean the actuator with brake cleaner and wiggle? Or just drop some lube down the rod without cleaning any crud?
Oil wise, is 2 stroke ok to mix with copper grease or must it be 5w30?
Is it normal for 1st gear to slow right down when taking foot off the accelerator? Compared to all other gears rolling with a smooth feel?Disco 3 SE Manual 2005 V6 2.7

1st gear thing is just engine braking I guess.
Doesn’t need to be 5w30 for turbo linkage

You should never be seeing black smoke in a modern Diesel. If you are there's something not right with either the fuelling or the boost/induction side. Check your fault codes for the engine and see if there's anything "pending"
Did you connect all the hose clips correctly when you were doing the belts?
When downshifting the resistance increases with each subsequent gear reduction, and that's obviously the desired effect. Why though are you downshifting as far as first gear?
First is a get you going gear, and you shouldn't need to shift below 2nd for normal road use. I pull a one ton trailer regularly with Disco's on the back and never need to shift below 2nd. Sometimes I will use the low box to get things moving then flip to 3rd high when enough speed is gained.
I never downshift to low box! Or, below 2nd in either range. When manoeuvring/reversing I always use low box for better control and less strain on the clutch.yµ (idµ - eAµ) ψ=mψ

Probably me connecting them together and worrying with the recent trauma hah
I can’t make out much on the YouTube videos. Can’t see any of actuator getting cleaned or lubed. So I can’t understand where I need to ensure the lube is going to go....
Do I just smear it on the ball and leave it to run downwards. Or is there anything behind the ball I’m not seeing?
Hopefully a successful clean down and lube up will do itDisco 3 SE Manual 2005 V6 2.7

This isn’t about towing and I am not on about downshifting sorry. I mean just starting to drive. Put it in 1st. Drive to speed ready to go up to 2nd gear. But the car will drastically slow down unless I put the clutch down.
I know it looks like engine braking - but the other gears don’t do that, unless down shifting.
If that makes sense?
Just doesn’t seem right to me.
As for black smoke. I’ve booted it a few times now and it’s stopped smoke being noticeable in the rear view mirror.
I’ll check for codes tomorrow.
Maybe a few helpful things I can do? The sensor in that oily box was wet I think maybe? The only air hose from my recent work was the big one above the radiator? If so I think it seemed slightly cracked? The jubilee clip was tight and the other side Was pushed on well. Maybe I can zip tie it down tighter?
I’ll get codes and then clear them. See how it goes. And Sunday I’ll be living the arm and resetting codes again. See if that stops the irregular boosting in 1st gearDisco 3 SE Manual 2005 V6 2.7
