I've had a surging while under load which I know is a Seized waste gate, but 2 days ago in the morning till the engine is warm there is a lot of smoke, I took the house off the turbo and there is oil around the veins and also the veins seem to wobble which I presume is a nakered bearing.
Could this be causing the smoke though?

Blue would be oil....
not sure I'd be too worried if the impeller doesn't hit the housing. Most turbo's will have a little side to side play because the turbine shaft runs on a very thin film of oil.
In/out play is apparently more significant and an indication something not right...

If the bearings have failed, the movement when it is running will allow oil past the seals, hence the smoke.

You will know when the bearing fails on a turbo - believe me Laughing


Most oil on turbo blades come via the engine breather rather than the turbo bearing

Sorry, I didnt phrase that well.

If the bearings catastrophically fail, you will know about it.

Often, before they catastrophically fail, but when they have worn, there will be a bit of play in the shaft. The result of this will be that the seals fail and oil past, causing smoke as it burns.
