I recently purchased a used 2012 5.0 BBP 6M CP BU/SEC 373 with 152 miles on the clock. Great car but it has been a gremlin machine as well. After the second trip to the dealer for the LCA creaking/squeaking issue the car has developed a burning oil smell after the first oil change at 1062 miles. I have spent hours looking for a leak or spill and I have had the dealer look as well. No evidence of a leak can be found but the smell is strong. I believe it emanates from the PCV or crankcase breather or the oil filler cap gasket. The smell is up high in the engine bay around the heads. I know the 5.0 is very unforgiving of overfilled oil and I have checked the levels several times. I switched the car over to Mobile 1 5w20 w/ a Mobile 1 filter. I cannot find any information on this issue. I have also speculated the Mobile 1 may have adversely affected a seal somewhere but I am just guessing here. Has anyone else experienced this issue with the new 5.0s? Thanks.
