850 T5 blue puff of smoke

M238 Volvo 850 T5 Northern Constabulary Code 3 3878964359 -
1:43 Doorkey (a very well done Code 3)
The car was a wee bit dilapidated when it was given to me, so it benefited from a new lightbar (Hongwell)

Did you see a blue puff of smoke?

I just wanted to post the update since the PCV replacement. Today was the first nice day on which I could actually see whether the oil smoke comes out of the exhaust. I drove pretty aggressively to test the symptom, but there was no sign of “puff” at all. So I’m assuming that PCV replacement cured the problem.

Before I went ahead with PCV replacement, I actually went to talk to my regular Volvo mechanic (let’s just call him Crazy B). I always thought he’s good and cheap, a difficult combo to come by. He, by hearing the description of what was going on flat out told me it’s either a worn turbo bearing or the valve seal, said that it’s not worth spending money on to repair. After my day’s work replacing the PCV, I must say that he fell of from the grace as far as I’m concerned.
