dealership tested oil consumption for 3 months - agreed there was a problem - repaired Aug 13/13 May 27/14 noticed an oil leak - dealership advised engine leak need to replace rear main seal or upper oil pan,will need to remove engine to check it out - could be part of original problem - have not had an estimate ** what is your opinion
