Thought I would put up an update.
As stated previously the white smoke is back. I had dismissed the oil mist seperator as it was done approx. 6 months ago. As it worsened I disconnected the EGR control valve and this worked for a little while. Then the smoke started agian. This was only when stopped in traffic. Then it started smoking while going.
I had the classic pressure release when I took off the oil filler cap. So after more reading of this site discovered one guy who replaced his oil mist seperator 3 times in 8 month intervals. So I thought as an experiment I took cap off and using rubber hoses clamped in a breather cap to stop the pressure building up in the rockers ie the oil galleries. This worked an absolute treat and points me back to the oil mist seperator/crank case breather AGAIN!!!
I have ordered the later one which does not have the fibre gauze on it I believe from reading another post see

This fits the AFB engine but is for the later engine and no reported problems as it is all plastic.
With the engine oil galleries being under pressure I reckon the oil feed to the turbo bearing was getting under extreme pressure and forcing oil into the exhaust hence the smoke. I was on the verge of getting a new turbo before I decided to revisit the original proble. I would not have expected this to happen but maybe once the first one has gone the
cr@p build up in the engine may cause new ones to gunge up very quickly.
Anyway get my new one on wed. Will post after that. 'Til then will run with my "breather cap".
