Just thought I would share my recent experience with you all as it may help you out one day! On holiday last week, my Disco2 TD5 developed a lack of power, vibration and sounded like it was running on 3-4 cylinders. As I was in South Wales I took it to the nearest dealer which was in Swansea. They diagnosed that injectors 2 and 4 were not working correctly and tried to sell me 2 injectors. Unhappy with this diagnosis I spoke to a friend who suggested that it may be oil in the injector wiring loom which is aparently a common fault. I asked the dealership to check this which they said they had and it was fine. Still suspicious, I decided to take the vehicle back home (2 hr drive) and get my friend to help me have a look. We picked up an injector wiring loom for £40 inc VAT and took the rocker cover off. We instantly found that a wire had broken on one of the injector plugs. As we disconnected the old loom we found that oil had also found its way into the multi plug located on the front left corner of the engine. We washed the oil out of said plug, refitted the new loom and job is all sorted. Runs and goes like a new truck! You may already know about this loom problem but if not, there you go. Cheers

Hello again, Finally had the exhaust manifold replaced by BG landrovers last week, It has indeed cured the squeal which is fantastic, very helpful people and completed the job when promised. Unfortunately the damage to the studs and head was worse than hoped and they had to replace 3 studs with inserts, one of which had to be 10mm. To get to one of the studs the Air-con system had to be discharged and then re-charged afterwards. The car was dropped off at 8.30 and I finally left their premesis at 6.00pm. The total bill was just under £500 inc VAT which was more than I had hoped. But at least it is sorted. Just to put the boot in I had the disco MOT'd today which failed on a leaking Power Steering box and the Emissions!!! Changed the steering box without too many dramas (£125.00 +VAT from M&M). Emissions could be an issue, and once again point towards the fact that it has been chipped. Taking it back to Alisport next week to get them to check the settings and hopefully get the reading down a bit. The maximum level is 3.001/m and we were getting readings from 3.47 to 3.75 1/m More money! Cheers

SUCCESS!!!! (I Hope!) I have finally had it confirmed that it is the exhaust manifold warping that has caused the squealing problem as you guys suggested.. After going around the houses again I was finally put in touch with BG Landrovers who are based near Monmouth. Paul at BG says that this is so common (on standard vehicles not just chipped ones) that he keeps a stock of re-surfaced manifolds. Cost to exchange the manifold, fit the new one replacing any studs that may have gone will be under £300 inc VAT and courtesy car! He also says that as the new manifold is "pre stressed" it is extremely unlikely that it will go again. Next thing is to sell the old turbo that didn't really need replacing and try and get some money back! Thanks again

The squeal starts around 2000 revs whether I am driving along or sat reving it on the driveway ( no load). Once the revs drop below 2000 the squeal stops and sometimes I can accellerate through it on the road and it dissapears around 3k. I do about 60 miles a day so get used to it now! but it seems less prominant when I am in 5th gear for some reason, or crusing on the motorway. I hope to check the pipes haven't delaminated at the weekend and may even tackle the manifold gasket if that does not prove successful. The vaccuum pipes all go back to a small unit mounted on the block. Does anyone know if this could be the source of the problem? Thanks for all your input guys, hopefully I will get it resolved soon.

Thanks Paul, everything seems to be pointing towards this manifold area Cheers

Thanks for your response to this. The Intercooler and fuelling mods were carried out by Alisport in Gloucester. Top job and makes an incredible difference when towing. Sounds like it may have caused the problem though!! Cheers

Thanks for the reply.. I have just listened to it again and it is definately coming from within the engine bay around the turbo side somewhere. I think I read somewhere that the Vacuum pump is built into the altenator on these. Is this true? if so then I suppose that it could be that! just expensive all this trial and error stuff

Hi, My 2004 (53) TD5 Disco has recently developed a squeal when accelerating. It seems to co-incide with the turbo boost starting around 2000 revs and increses and decreases in pitch the same as the turbo whistle. I spoke to a turbo specialist before Christmas who suggested that I check for end float on the turbine shaft. I did this and indeed found a little end float so I have put a new turbo on at great expense, but the squeal remains. I have checked the vacuum pipes off the intercooler feed, turbo and air intake pipe from the filter box for splits and all seems ok. The car has done 91k now and was chipped around 10k ago along with an upgraded intercooler. She still pulls like a train even though she squeals like mad. Has anyone got any ideas what it could be? Someone in a previous thread mentions exhaust manifold gasket, is this a posibility here? Cheers Landy Addict
