Smoke on idle

[croydonS13]

I had a full rebuild earlier this year. Since then I havent 2000 miles as yet. About 3 or 4 times recently I have had smoke on idle, it doesnt do it on startup or boost, only when the car is warm and has been sitting stationary for a few minutes. the smoke smells oily and has a slight tint of blue. Any ideas on what this could be?

turbo seals - try a one way valve

Just decided to go stage 2 so getting a T28, this should cure the problem if its turbo oil seals right??

Are there any other possibilities for what could cause it?
