Hi Guys,
I have a 2011 XC90 with the 3.2 awd. car runs good but when you go to get on the high way or accelerate hard I get an oil burning smell it lasts only for a 1 or less then its gone.

It is driving my wife crazy and i would love to fix it for her.

Any suggestions to what this could be???

Thanks for the help

 

are you consuming oil or just dealing with a smell? How's the fuel economy? You don't mention mileage so I'm wondering if the cat converter or O2 sensors are on their way out and your fuel trim is a bit rich etc. Any signs of leaks/spotting etc which can find its way onto the exhaust manifold etc?

 

The suv has 150000 miles. It was using oil and I replaced the pcv apperatus . No complains about fuel mileage .
Theres no oil leaks in the garage floor.
i have ordered new fuel filter. Volvo spark plugs . Air filter and oil fill cap gasket hoping one of these fix it.

 

add a cabin air filter to your list. If your PCV oil separator failed at some point allowing the oil in the blow-by to get into the intake, you may have some residual oil in the intake air plumbing that can be cleaned out.

 

so Oil could get on the cabin air filter? I dont understand how the 2 are related. what would a new filter do?

 

i did not see any oil leaks. new volvo plug, fuel filter and air filter did nothing for the smell

 

cabin filter did nothing to help with the smell
