Good evening , I'm from Brazil and I have a allroad 2002 2.7T V6 with 70K .
Everything always revised, oil and fitros always changed at the right time , everything perfect when walking on a freeway to slow left a lot of smoke , suddenly an hour to another , when it keeps accelerating in motion the smoke out , but when decelerates much smoke comes again , let stopped working is also leaving a lot of smoke .
All indications to be turbine, the turbine but can be to be perfect and suddenly move much oil , so that oil comes to have a residue at the tip of the exhaust ??
Does anyone have any tips of what can be ?
I hope you can help me.

Thank you very much.
