I have a 2014 XC90 3.2l bought new from Volvo dealer in 2015. It is still under warranty with 28,200 miles currently on the vehicle, during the last 8200 miles I have added 4 quarts of oil to the motor. There are no visible oil leaks just excessive oil consumption. The Dealer has had it for the last month I have been informed that they have gone into the motor, to what degree I'm not sure, and have taken pictures and sent them to Volvo for diagnoses. I have just been informed that Volvo's recommendation to fix the problem is to reseal the valve cover. Does anyone have any experience with this repair? I am not an automotive technician but I don't see how resealing the valve cover will fix the problem when it's not leaking oil on the exterior of the motor. Any help would be greatly appreciated.
