Disco 2 TD5 after Intercooler Hose Fitting

[Shaker]

I recently posted about my disappointment with the performance of my Disco 2 TD5 manual.

I had several very helpful replies most of which suggested starting by looking at intercooler hoses.

Last week I replaced the intercooler hoses with silicone hoses from BAS in the UK, I must admit that I was very sceptical that it would make much, if any improvement.
Of the 3 hoses, the one that not only felt thin & soft, but was of a totally different material to the other two, was the small one at the turbo end. The other 2 were of a much more substantial material.

Well, after driving it for about 5 days I would say that it has made nearly a 'whole gear' difference pulling away from low speeds. The vehicle also feels quite lively & it is much more of a pleasure to drive.

I will now fit an EGR removal kit & oil catch tank to the breather.

Thanks to all those that offered me advice.

Funny you should mention this, I fitted my silicon hoses on Sunday arvo and I have to say I got a better improvement from them than I did from the larger intercooler:mad:

It is a bit more responsive off the mark and seems smoother over the rev range and has improved turbo lag a bit as well.

Can't wait to get the 3" done, once this is done, I can have the chip and turbo matched to the intercooler.

Gday, I see from another thread you got the silicon hoses from the UK, is there no-one in oz that supplies them ? or was it cost related ? We use heaps of silicon hose at work on big marine diesels if they are straight lengths I might be able to use that.

They were around $70.00 cheaper from the UK, got them in 5 days too!

There aren't any straight lengths.

Thanks Shaker,didnt think I could be that lucky..

Just curious how many K's you blokes had done when you replaced your hoses.
I've done 142K so far.
Starting to think this is the cause of my erratic running TD5.
Runs fine until you put the boot in to it, IE: overtaking or a quick get away at the lights.
Since I started taking more notice, I would say it's worse when it's been running for awhile.( Heat in engine bay )
I'm thinking the longer the engine is running the softer those hoses get, hence a more pronounced hesitation or lack of performance.
Cheers Lionel

[Skellz]

If you need info on doing you EGR go to discovery2.co.uk the guy on that site has step by step with photos and all the tools need to do the job

Great sitfor info on doing some mods:D

[BilboBoggles]

So can anyone explain why effect happens? surely if the hose swells up that could only result in a very miniscule amount of turbo lag. I mean it's not going to be able to reduce the pressure, once it finishes swelling up. Perhaps it's because the old hose is leaking or is constricted in some way? Is that why new hoses make any difference?

200,000kms, but mine was sluggish, not erratic.

Apparently the hoses can delaminate & then air gets between the laminates & swells it up inside restricting the flow, much like a cholesterol filled artery.

[Gold_TD5]

I will know soon enough, BAS have sent my new hoses off today.
So in a week or so I will have them on and problem solved or maybe start looking else where.;)

I'd also be looking at the wastegate modulator, oil in the injector harness, fuel sensor, throttle position sensor, crank angle sensor, air in the fuel system, to name a few.

[Gold_TD5]

Maybe erratic is not the best description, as stated the engine runs fine until I expect that little bit extra.
More a hesitation, power drops off then comes on like nothing has happened.
Around the 2500rpm mark. Increasing the boost on the turbo made it worse (although it has never gone in to limp mode) which leads me to believe the hoses are at fault, same with heat after running for a while.
The rubber goes soft and causes the hoses to distort. Just a theory.;)
Will post up results after fitting new hoses next week.
Just for the record, I had a new injector loom fitted about 10K ago.
Thanks for the input.
Cheers Lionel:)

[green_disco]

Anybody happen to know if the BAS and TD5Alive hoses are of a similar quality?

TD5 alive hoses are Samco 3ply hoses.

Al my hoses are 5 ply for a nice robust hose that should last for ever.

Gold TD5,
Ive been playing with my new Nanocom over the weekend. Ive noticed that between 2000-2500rpm is where full boost comes in, with a reading of about 1.12 -1.14 bar Than to me it appears that the waste gate opens and boost can drop back to 1.08 -1.09ish. I'm wondering if some of the power loses we find can be just put down to the waste gate opening too much or too long. Just a thought I'm kicking around.
Anyone else with a boost gauge may be able to look into this.

G'day Zute
I am thinking it's pointless messing any further with boost adjustment till I eliminate the possibility of the hoses being crook.
If there is a member on the east side want to do a little experimenting with their Nanocom, please PM me and we can hook up and do some tinkering.
Should have the hoses fitted up by next weekend.
(thanks Pete)

Thats right,
mine was that bad in the end that when I wanted acceleration all I got was black smoke and going no where.

For anyone interested here are a couple of pictures of the hoses i got from BAS.

The hoses seem like a high quality product to me,

And it looks like my originals where a bit swollen too

I've been searching around for why my D2 TD5 has been sluggish as of late with alot more induction-type noise, so after reading this topic I reached into my engine bay and gave my hoses a good squeeze. What do you know but I could completely collapse them with my fingertips.

Within an hour, I had the two replacements (OEM for AU$80) for the turbo-intercooler side as the EGR side was fine. From from ringing around, the OEM part was changed/upgraded in 2002 and have a different construction. To be sure, both hoses had started to de-laminate and had several bubbles like the one shown here.

http://smilebaby.com.au/af-images/D2-IC-DeLam1.jpg

After replacement I could not believe the difference! A couple of months ago, removed the EGR and it all came together with the new hoses. I forgot that the TD5 could actually accelerate. Engine running is also smoother now.

Thanks! You've given me back my Disco Joy! :p

order my ic hoses from bell last friday, arrived monday :D
cheers pete, look forward to seeing any gains once they are fitted.

[Yorkie]

ok so i fitted the new hoses from BAS last week and have to say very happy. :cool:
check out the pictures of the smaller hose from turbo :eek:

https://www.aulro.com/afvb/images/imported/2009/05/92.jpg

https://www.aulro.com/afvb/images/imported/2012/11/69.jpg

i reckon there was approx 40% reduction of internal space due to the delamination of the old hose. the other hose looked ok.
car goes better and next mod the egr :twisted:

cheers
yorkie

[discowhite]

FINALLY!! thanks for the photos yorkie!!!! now we have something to show people who ask what de lamination is and how dose it stop my TD5 from going...

top work.

cheers phil

[Redback]

Wow, mine didn't look anything like that, that's amazing:eek:

I was amazed by the difference that my silicon hoses made, mine are the 3 ply Samco not 5 ply like B.A.S.:o

[Yorkie]

mine are the 3 ply Samco not 5 ply like B.A.S.:o

so mine should go faster then..... never mind yours can go further:p

[Urban Panzer]

I dont know whether its a sales pitch, or its true, but do the BAS hoses have this ?

Quote from TD5alive site


All our premium grade silicone hoses come with an oil resistant 'flouro' liner, which has a dark grey colour. This is used as an important protective barrier, to prevent oil from migrating through the layers, causing discolouring and delamination of the hoses. This lining is very expensive and is often omitted in 'budget' hoses, so is a good indication of quality

[Bytemrk]

Urban Panzer, I'm not sure of the answer, I'm sure B.A.S. will be around to put us straight. But you can see from these pictures the inner layer is a different material from the outer on the BAS hoses.. I'm happy with mine.

Thank you gentlemen for a very interesting artcle, question where in Brissy can you obtain the BAS hoses.:D

[omvanders]

Military, I'm guessing that you need to order them direct from the UK website. I just wish they had hoses listed for my Disco 300 TDi :(!

This is from SFS's site



Q. Are the hoses suitable for oil and petrol?
Standard hoses are only suitable for air and water, for oil vapour we offer fluoro silicone hoses.

I've e-mailed Bell Auto twice via their web link re ifo on intercooler hoses and EGR kit but so far no response. I dunno if this is a Firefox thing or I'm disappearing into a black hole or what. Is there an easier way to contact them, B-A-S if you read this please PM me. Am I the only one with this problem.

It seems the Silicone hoses are not on the site at the moment;)
Maybe PM Pete and see how you go, strange from my own and others here the service at BAS was exemplary.

[Stuart02]

Hi guys, I just received my hoses and EGR blanking kit from Pete yesterday, and have been talking to him on email - using firefox btw.
Anyway, look under 'news' on the bellautos website, and you'll see the gear.
Now I just need to figure out how to get in there and fit the stuff!! Cheers

[Ean Austral]

Gday All,fitted my silicon hoses today and was surprised to find that after 200k the hoses I took off were fine.Got the turbo side replaced under warranty by L/R at 20k.
So no noticable difference but atleast they've been replaced.New rad and intercooler next,doing EGR tommorrow.
Cheers Ean

Yeah - my hoses were fine too after 140k kms - but I still think the silicon hoses have much less flex which has to be a good thing... one trouble I had was getting the hose-clamp on to the intercooler outlet as neatly as I'd like because there's not much clearance with the fatter silicone hose on. I hope it'll be ok...

[Skellz]

Found out yesterday after speaking to some one about the hoses is they were change in the 2002 2003 models to a better stronger hose I thing they have a red or white line in them and do not have the problems of delamernating. So depending on what year your car is will mean you may have the better hoses

:):):):)

Your welcome mate,

Hi Pete
Just ordered mine.
Replaced the originals with 3 ply items and I am not happy.
Had a couple of blow off's with heavy duty wide clamps.
Will replace them with the STD clamps.
What is that spring type spacer/tensioner in the STD clamps for?
I can easily get the NORMA clamps but not the springy thingy.

[gingz]

Hows it going boys,

This is my first post on here.

Just received my silicon hoses this morning. I have a question....I can see where the two dog leg hoses are to go, but the elbow, Where does it go?

I have never really played about with engines before.

Cheers in advance

[Rudolf]

, but the elbow, Where does it go?

I have never really played about with engines before.

The elbow goes onto the turbo and pipe.
Same size s bend goes onto same pipe and intercoolers.
Odd sized pipe goes to intercooler and inlet manifold.
Be carefull when working on the pipe betwen turbo and intercooler.
There is a small pipe attached to it that goes to valve for the waste gate.
It is easiest to unbolt the valve and remove the small pipe, then work on the hoses. Put everything back together again then bolt the valve back on.

[Rudolf]

Very rude of me!!!
Welcome to this forum.
I enjoy it more than any other forum.

[gingz]

Cheers Rudolf,

How long is this likely to take? Does the elbow have to be cut? am guess with out looking that it must go on both ends?

Am wondering if I should get the ERG removal and do all the work at the same time.

[Rudolf]

Get the EGR kti and do it all at once.
For the Turbo hoses looking at about one hour.
For the EGR I dont know. Did not do it myself but should not take very long.
If you have butter fingers like me Well maybe longer.:D

[that_kid]

if i could get a reply from BAS on email id order the hose kit, their website doesnt seem to be working properly for me either that or im just retarded and cant find the link to hoses :S

[Hendrik]

I tried them as well, got no reply. So i don't think your that retarded lol

Cheers
Hendrik

[Rudolf]

cant find the link to hoses :S
It is under the newstab. Just scroll down.

I ordered them from this mob

[charlietortoise]

Hi all, maybe an old but a very good thread. I have owned my disco 2 td5 for 10 years and she has gradually slowed down and feels sluggish and slow. I put this down to age and mileage and was debating a larger intercooler and chip. Following your thread I have just replaced the hoses and cleaned out the intercooler.


Its a new car! Back to how she was, very little black smoke and now at about 2500 rpm I can feel the turbo surge again when overtaking.


Great info thanks chaps.

[bob10]

Take your time with the EGR kit, a few bits to remove. There is a 3 way fitting on the vacuum line, from memory, that needs to have a cap put on one spigot, when the vacuum line to the EGR set up is removed. Super cheap has them. One tip. Pick a kit that has a lip around the pipe that connects to the inlet manifold. My hose blew off just outside of Longreach, my kit just has a straight flange. I have to do some creative clamping to keep the hose on. Bob

[series3kev]

Hey all,

Some good info on this thread. I de-EGR'd my D2 a while back, and I've also removed the middle silencer in place of a straight pipe. Both mods made a noticeable difference to the performance (and a noticeably louder 'bark' with the straight pipe!), so now I'm looking at going with the silicon hoses.

Just a thought to those that have already done this...is it better to flush the intercooler through first, before fitting the silicon hoses? Mine's on 207k km's and I don't reckon it's ever been touched.

Mine also had the injector harness replaced at some point in it's life, but looking at the ECU the other day, I noticed there's oil on the red plug again....

Cheers,

KevF :D
