i think ive got a similar problem, but i think my exhaust wheel as partly or fully come off. It "doses" still, but very faintly.
yesterday i was driving at 100km, and approx every 15mins, a puff of blu ish looking smoke was comn outta the exhaust?
could this be because oil is going through the turbo into the exhaust? i am not sure about this thing, any info on this would be helpful.
thanks.
