Turbo lifespan

[gords]

Do you get a lot of black smoke when on full throttle Gords ?

No, not particularly. I does smoke on ocasions but it doesn't chuck it out. If anything, it'll smoke then flooring it from low revs, until it picks up.

[muddyweb]

hmm.  OK.. I was asking Allisport about other possible causes for your performance and he suggested that a faulty lift pump could be causing issues.   That is often accompanied by extra black smoke when you floor it.  (Over and above the normal 'turbo lag' levels)

The fuel sedimenter should be brimming full of fuel, if it isn't then that is another symptom.

Thanks Tim

How do I check that? As mentioned previously, I tried removing the drain plug, but got scared off when it seemed to turn a bit each way, but didn't want to undo. It's a plastic plug - does it just need gentle persuasion? I REALLY didn't want to break it (Belgium is coming up!!).

Is the presence of 1bar pressure from the turbo indication that all is well there, or could some part still be non-functioning?

Gords,

Did you have a roofbox or anything else on the vehicle which might impede forward motion? Are you expecting to be able to accelerate in 5th around 70mph? Have you tried dropping a notch to pick up acceleration?

My experience with Piglet is that the autobox does shift at different times, and kickdown *IS* required to move from 70mph+

Has this happened since you played with the EGR?

Do you still have the old wheels - or someone close by - to swap them back and see if that helps?

We had canvas bags on the roof for the holiday, but not to/from Wales - the performance (or lack of) was much the same.

From around 50mph upwards, the word "acceleration" is somewhat extravagant! It's more a case of the speed increases gradually over time

I assume it's because of the altered gearing due to the tyres, but the power seems to be too high up the rev range. Talking of rev range ... what is the "red line" for a TDi?

Changing down to 4th doesn't have any effect unfortunately. It appears as though I have little power until around 2500rpm and the engine doesn't want to rev much past 3500rpm (rough figures).

While driving through France, on a few occasions I got it upto around 80mph and it managed that to hold that (on the flat) reasonably well. Getting to that sort of speed is only attainable downhill though

The EGR was removed post France/pre Wales. The take-off and low rev picup was much improved, but it did not affect the top end at all - although it (seemed to) get there easier.

I keep thinking/feeling it's some sort of fuel starvation, but haven't found proof of that. Otherwise, it just seems like it needs a few extra horses :roll:

Unfortunately, I don't know anyone around here with standard size tyres, nor do I have any.

I have 235/70s on my D1 in Sunbury if you wanted to swap/try one evening.  Cheers.

If you can't find anything Gord then we'll have a look at it in Belgium and try a couple of basic tweeks to the injector pump to see if it makes any difference.
You can alway put it back if it doesn't work or you find another problem.

That sounds like an offer I can't refuse  :D

[drmike]

I'm not clear on the pipes - have you actually checked that none of the pipes are split or delaminating.

I'd have thought that was the very first thing to check. When my pipe from the intercooler had a small split I lost power just like you and blew black smoke just like you.

I also know these pipes do delaminate quite readily but Allisport will have mentioned this I'm sure.

I have taken most of them off and checked - I would assume that I wouldn't get full boost (1 bar) if any leaks existed? I certainly didn't when a jubillee clip broke :shock:

It appears to be low on power but it's not blowing excessive smoke.

There was no obvious sign of problems with the pipes, although they are very soft - but then, they might be like that off the shelf :?

[drmike]

Well it sounds like you've covered that aspect but personally I would check them all again as it's easy and cheap and I'd have thought the most common cause of failure.

In my limited experience new pipes are quite firm while ones that have been about a bit are softer. The one that split was very pliable.

I like cheap solutions! If you want to make it expensive then Allisport will sell you some lovely replacement pipes. I don't know the Allisport bloke's name but I do know he is very highly regarded and I'm sure he'd be able to give some really sound advice - you're not local to him are you?

[gords]

Well, silicone hoses are on the list ... along with ... :roll:

Need to come with the right "justification" for an uprated intercooler - that's I reckon  :lol:

This is a long shot gords but I recently has a problem with my rear rubber donut thingy on the rear prop. I found at 55mph it just didn't want to pull through and up to 70mph very well. OK this came with a strange but mild vibration that felt like nothing I'd ever experienced before but the rubber was perished and splitting in places. I changed it for a new one and wow the power transfer was much improved. It didn't feel like the power was being 'lost' at specific speed. Somehow the loss of power was down to a loss in energy through the prop.

It maybe worth checking your rubber coupling and your U/J's just to make sure you're not experiencing a similar thing. Long shot I know !!!

[gords]

This is a long shot gords but I recently has a problem with my rear rubber donut thingy on the rear prop.

Well, funny you should say that! I was under the car recently and noticed that the donut was looking a bit shagged :shock:  It is a bit cracked and quite compressed. Maybe I'll stick a new one on :)

[Mace]

If you've got time I would Gords. It's not hard but you need to remove the prop from the brake drum end first as the rubber donut has a central hole that take a pin on the end of the prop. Loosen all your bolts first mind, then remove the front end. Also there's a metal sleeve on the end of your prop with a rubber insert, I couldn't get mine off at all to replace it with the one that comes in the kit, it's made no difference not fitting the new one at all.

If you can buy a genuine Land Rover one. I spoke to my local LR specialist and he's had two or three of his recently fitted Britpart ones that have split again within 12 months of road only use. LR charge £40 + Vat I think. Also most dealerships hold them in stock !!

Fingers crossed.

[gords]

Well, I fitted a new coupling ring/donut thingy today ... another step in a good direction :D

It has removed that annoying jerking when accelerating from slow speed, gear changing is smother and the drive is generally smoother 8)  I don't think it's done anything particular to the top end but it's certainly made it drive better and has possibly added a few mph to the top end.

The donut that I took off, when compared to a new one, was very obviously shagged :shock:

Cheers Mace :)

[Mace]

As the man at Tescos would say..."every little helps" :-)

I was surprised to notice such a difference in mine too. They really don't degrade in the same way as a U/J so I would imagine we all take them far beyond their useable limits before chucking them away.

Keep replacing the cheap bits Gords and you'll get a sense that you're actually achieving something. The expensive bits are harder to swallow.

Thank you Budgie :D

We (Budgie) made a simple, 2 minute, tweak and it's made a marked improvement :D  \:D/

Coming home from Belgium, I was able to maintain/cruise at 130kph and the hills had much less of an impact! Yippie :D

[Xtremeteam]

so whos gonna tell me what you did??

i made a wee tweak on sat for goin to drumclog by fitting a vent in the actuator pipe that runs from the turbo to the actuator so at low revs it breatsh out the hole keeping the actautor shut for longer till the pressure rises

[Thrasher]

/me seems to recall helping by sipping Jupiler and trying to understand what makes these engines go :-)

I now understand one thing about diesel fuelling. It's bloody complicated. However - most impressive sight of the weekend has to go to Mad George, who managed to engulf the entire site in a cloud of oil and diesel....TWICE :-)

[gords]

so whos gonna tell me what you did??

We turned the diaphram in the injector pump from 12 o'clock to about 2:30 (between 2 and 3 o'clock)  

2 screws, 2 torx, pull off cover, turn diaphram, put rubber bit back in place, put cover back on, put screws back in. Job done 8)

Hello Gords :lol:


That was the adjustments me and Simon were talking about in the Alps  :D but to make it work better the turbo needs tweaking and a larger intercooler to help feed lots of extra cold air in for that bigger bang to go with that extra fuel :(bloodshot):  :(bigwicked):

Yes, a bigger intercooler is on the list, but this simple mod has given enough to make it much more driveable on the motorway. That'll have to do for now :roll:

[Arightpest]

fibber you know you want one      :twisted:

[Budgie]

Hi Gords,

Glad to hear it worked, you can always go a wee bit more if needed.  :D

And thankyou to Neil for his support while we were working on it, I'm sure it wouldn't have been the same without him!!  :roll:

We got back last night (Thursday) after spending two nights with Duncan Brown on Skye (it rained most of the time but at least it washed the Disco for me! :D).

I'll download my photos tonight and post them later, including the damage!
