Hey all, just noticed my saffs got a bit of a habbit

Its only just had a top end rebuild and newish turbo

.
But after periods on overrun, when i hit the throttle again it chucks a noticable amount of blue smoke out, whats this point too?
There isn;t a whisper when its started from cold or anything, and after a bit of throttle it clears untill next time you have some overrun?
