No smoke at all on startup. Only usual condensation. Coolant levels are normal and so it is just the cold mornings.

I even checked if there was smoke out of he dipstick or oil filler and whilst there is some puffing of air there is no smoke.

I have been scouring the web trying to find any other possible causes such as boost leak or failed turbo but whilst there are no symptoms the same as mine...it is almost certain IMO to be a Ringland.
