[quote="CitroJim"]I'll go for worn valve guide seals too but before you whip the head off to replace them...

if it was the vave guides would it not burn oil all the time? to me it seems oil is pooling somwhere when on idle, then when you boot it it big cloud then it clears untill you idle it again. there was some play in the turbo shaft, i,ll clean it up and check it over.

I dont think it would. On a petrol the problem is more noticeable at idle, this is where manifold (negative) pressure is strongest.

On a diesel without a throttle, that vacuum will be there when driven in ost circumstances except of course on boost when there is positive pressure inside the manifold. If it was not smoking on boost, and it was the valve guides, the problem would not be noticeable, so it could still of been valve guide seals.
