you mean 6-7 bar? that is far too rich. whoever told you blue smoke was the car running lean is a bellend.

it could be turbo seals (but thats generally a grey colour smoke). do a compression test. does the car tend to breath heavily out of the breather on the cam cover? does the car use any oil? run badly at all?
