Grab hole of the turbo shaft and have a feel . A little bit of up and down and I mean a little is ok but end float is not good . If you can get at the downpipe bolts onto rhe turbo you will see oil if it's goosed There was a little movement when I checked but not a massive amount at all, I ll try what Rich said and report back my findings

Ok heres my findings so far,
Engine has been running for about 30mins with the pipe from the intercooler disconnected (air going straight into manifold) and I m not seeing any difference, still burning oil somehow, double checked to see if I had smoke blowing from the oil filler cap, and have none, I have pressure there at idle and suction as I raise the revs. the inlet into the manifold, whilst pretty black didn't have any wet oil in it, saying that though, I m sure the turbo is knackered, at mid to high revs its spraying oil, theres a secondhand turbo on ebay at the moment for £130, is that worth a punt before I shell out for an engine?

I looked after a fleet of 2.8 dailys back in the late 90,s and they were pretty tough things up to 300,000 miles .if it's starting on the button then I doubt you have a big wear issue in the engine . Injectors need a service every 100k and Turbos seem to do around the same mileage . Diesel pumps problems are usually poor or non start .

Yeah its always started fine, no issues there at all, the injectors will probably need a good service, judging by the state of the oil this thing has'nt seen a service in years!

Remove the exhaust downpipe and look at the exhaust housing/wheel on the turbo. if its oily then that will be the cause of blue smoke. If it starts from cold fine the compression must be half decent.
i recently had this issue with a clio dci, heavy blue smoke when accelerating from cold or after 5 mins of idling but started up on the button hot or cold. No play in the turbo shaft but loads of oil in the exhaust housing, rear seal was worn and letting by oil and oil spraying out of the compressor housing when the boost pipe was off. New turbo and no more smoke.

Yeah I m starting to think could be the hot side of the turbo, the downpipe looks easy enough to get to, the engines roasting at the moment so will have to wait for it to cool down before I attempt removing it

Well disconnected the downpipe and theres no oil, just dry black residue, so guess its either rings (smoke stop treat has made no difference) or valve stem seals?

Did you put a bootle of Forte through the injection system?

Did you put a bootle of Forte through the injection system? No, I got so much into the turbo theory that I completely forgot about the injectors! Please excuse my 'newbieness' to all of this but what will running injector cleaner through do exactly? (I remember I had an old Saab 2.2tdi where the injector seals had gone but that gave me starting issues to the point I scrapped the car because you needed to remove the camshaft to get to the injectors!)

Cleans out the injectors to give a better spray pattern and hopefully reduces the amount of smoke. Have you had a chance to drive this far on the road, sometimes a decent run will clear things out in a way that just having it running up to temperature won't.

Have you had a chance to drive this far on the road, sometimes a decent run will clear things out in a way that just having it running up to temperature won't. Taking it for a drive is a bit risky round here but not impossible, the fact I ve seen no improvement from adding smoke stop and disconnecting the turbo isn't really encouraging, I think another lump will have to be the way forward, at least then I can rebuild this one at my leisure, or just simply use it as spares, I ve found one on ebay, £350 for a 113000 mile engine, its in Bolton so I m looking at courier prices, I m in no major rush to have it running, I ve still got the whole of the inside to fit out and a few patches of welding (one of which is right next to a chassis mount so thats gonna be a pain!) so plenty to get on with, I will give the injector cleaner a go though, see of it clears it up a bit, its not that smokey at all at low revs, just billows out at mid to high range, so a little drive around the block is'nt going to draw too much attention!

Stop smoke will do sweet FA for injectors. Literally nothing. I mean, it pretty much does literally nothing in any scenario, it's an oil thickener. May as well fill the sump with EP90 if you want to go down that route. If it's an injector, fuel-system cleaners are a good first port of call and are inexpensive but you really do want Forté for this.

I was thinking down the piston rings route when I added the smoke stop, I ll see if I can find some forte tomorrow and give that a try.

It wouldn't start well from cold if the rings were knackered IMO
