hi everybody i'm a new member to this great site. I have read all the threads with reference to turbo diagnoses and I think mine is a candidate for a coat of looking at. as the car is in regular use I dont want to remove the turbo until I have a new one in hand but could anyone tell me if any parts are available to repair it. I am working on the idea that if you can buy a recon turbo the parts must be out there. Also what is it that actualy packs in is it bearings or impellers or what. any help would be appreciated. thanks.

YES, you can get a turbo rebuild kit, they are really simple to overhaul, its seals and barings basicly, the impellers should be find unless is swallowed a nut.
They cost about £20, which is brilliant compared to a new turbo.

And they work as well as an alternator or water pump rebuild kit....you rebuild it every other week
Best bet is to buy a new one and replace it, or take it off all together. Also they last alot longer if you don't allow it to kick in before the engine is at operational temp.

I would disagree with that entirly, rebuilds that fail are usually because they are rebuilt incorrectly, not properly lubed on reassembly, short cuts have been taken, the parts have not been preped properly.
When you get a recon unit, they are as they say reconditioned, however they are as good as a new part, and all they are is parts rebuilt by someone who knows what they are doing, and in many cases just using the kit that you and I could buy.
Dishwasher is a good place for most cast parts to get them clean, I have a master cylinder in there right now!

Dishwasher heh? I would have to try that while the wife's at work. Wouldn't be a bad idea to put a second one in though

Yeah, its great, cylinder heads, manifolds, anything, common sence has to be used of course, if its going to become a rusty wreck then its not a good idea, but my master cylinder is looking good!

Landrover dealers stay away from them.
First thing to do is, phone around diesel shops and see if they will overhaul it for you, or do a trade on a overhauled unit with your old one. I doubt it, but you might get a good price on one.
Is it the garnet turbo?
This is for the American market, but it goes you an idea about what your looking for T3 turbo DIY rebuild kit
They can be got here, I know because there is one sitting in my friends garage, for his 2.5 TD turbo.

Is it true that you should run you engine at idle tickover for 10-15 seconds before shutting it off to lubricate the turbo?

Yes, when you turn the engine off the turbo will still be spinning, the oil feed stops, but the turbo is still spinning down now with no oil being fed in and leads to premature failure of the bearings as these rely on a film of oil round the bearing.
When you see these twits reving their engines before turning them off, all they are doing is causing damage (if they have a turbo).

£20 for the kit!

Better buy 3 Big. You will need the extra 2 at week two and week four after the first one. Then you will buy the new turbo

First off, let me say if you can get a kit for £20, then its worth having a go. But you need to be aware that these things a built to incredibly tight tolerances, tolerances you will need to check if your turbo is going to perform as it should. Do you know what diameter the compressor impellor should be? if this is under size due to wear from scraping the outer casing, then you are wasting your time, it only takes the clearance to be out by a fraction to seriously effect the turbos performance. Also be aware that once removed and cleaned you will need to balance the impellor assembly - something that requires specialist equipment, remember these things spin at around 120,000 rpm, if its out of balance it will soon knock out your new bearings. Again, I am not saying dont do it but be aware, if your turbo needs rebuilding chances are that there is some damage to the impelllors / casing, damage that will not be obvious to the untrained eye, damage that will still be there when you re-build.
To sum up. DO YOUR RESEARCH. get the specs. and some good measuring equipment- and then make your fortune re-building them for the rest of us !

big beni, a load of good neighbours have cast their opinions but to be clear, you haven't exactly told us what the problem is.
Whilst most of the advice is sound you could do yourself a favour by giving us a better clue as to the symptoms. This would benefit you and any others who suspect the same problem.
Clearly if it is making any kind of noisy scraping sounds then you might just as well consider it done for as the walls and impellor are most likely damaged. You could still try repairing it but as others have said the balance and performance wont be right and you will certainly be fixing it again soon.
On the other hand if it is just seals and minor bearing wear causing smoke then a service kit may do the job (emphasis on maybe). You have to establish why the bearings and seals failed in the first place so some common sense and a patience is necessary.
Thoroughly clean every part to look for signs of scraping and over heating. Its extremely hard to tell if its been overheated and warped even by the slightest amount that's why your told to have proper measuring equipment.
However if you go ahead with a service kit you could try bench mounting the components and use a simple dial indicator to measure any run out the best way you can . If you can't do these things then your relying on luck.
Remember also that if a turbo has blown its seals and you conitnue to drive it your causing serious damage to the oil which could wreck the engine.
