Yep, cleaned it out with paraffin.
Don't think it is damaged, was in pretty good shape.
Its more of a metallic screeching noise now, kind of like when you get dirt in an electric motor.
 
Ok, is this something I can do on my driveway, or should I take it up to the farm? the ancillary belt is the one that runs everything isn't it?
 
Have taken a photo of the inside (hopefully attached). There doesn't look like there is any wear on the edges of the impeller, but if I try to turn it with some pressure it seems to get stuck? Also, quite a bit of oil.

Can still only move it about 1.5mm in each direction though...

Don't think you should have any end float (in and out), you will have a little radial play (side to side / up and down) as you have no oil pressure to 'float; the turbine shaft, however 1.5mm does sound to be more than I would expect (is that measured or estimated?)
 
Assuming thats the cold air intake side, it should be virtually spotless.
What filter set up are you running?
 
That looks like a lot of gunk in the turbo, is te engine breathing heavey? Or was it befor you did the head gasket?

Yes, there is quite a lot of oil about...wasn't there before I did the head gasket. It goes all the way inside the air intake pipe too

Is the head gasket in the correct way round? It does fit the wrong way round aswell, my mate did it and just as I was about tighten the head bolts I spotted it, there should be a little tab on the drivers side towards the front, with some hole that translate to its thickness.

on a tdi tab with holes denoting thickness should be between 3 and 4 injectors position
 
If you have oil in the intake pipe are you sure you have connected the cyclone breather pipes up correctly, does the bottom outlet pipe head towards the sump and the one on the side connect to the intake pipe? Not sure if you can physically get them the wrong way around without looking but worth you looking. Other things to check, is the oil level too high?, if you remove the oil filler cap with it running is there a lot of air being pumped out?

Just checked the cyclone breather. Seems connected the correct way around!
Not run it yet, as it's raining. Will try in a bit.

Might take it off to make sure it is not blocked.

I think the oil levels are slightly high, but it didn't do this before I changed the head gasket and I haven't touched the oil since I got it. I was planning on changing the oil this week.
 
WOOOOHOOOOO, FIXED IT!!!
So it turns out that while I was looking for the wastegate actuator that I hadn't actually tightened up the bottom nuts on the inlet manifold. Not gonna deny it, that was pretty dumb!
I am really happy now, it goes so much better than it did before I did the head gasket. Will change the oil at some point soon, as I am guessing that the fact that there is too much means it is all going down the cyclone breather a lot.
Thanks everyone, not a usual problem I know!
 
Well done for getting there, and doing the HG yourself!

I have to admit as I read through, I didn't think it was the turbo.

Unless it is a roller bearing turbo (they don't have them) it would be a journal bearing where the shaft 'floats' in oil and there is always some left to right play.

Movement in and out (so inline with the shaft as if you were trying to slide it in and out of the turbo) is bad...

Thanks :)

To be honest I am pretty pleased with myself. I was going to get someone to do it, but I am glad I didn't. I have learnt so much.

It doesn't make me afraid to do the chassis project as much now...
 
Glad it's sorted and you don't just jump in and but a turbo, you won't do it again tho now, you learn by your mistakes,
