Just had the valve cover gasket replaced yesterday at Performance Technic in pleasanton. Total was $516 which included replacing the Valve Cover Gasket Set - N52 and Camshaft Adjuster Gasket. Dropped the car off at 9am and didn't pick it up until 5pm. Not sure if it actually took that long, but I'm glad its finally fixed. No more smelling smoke while driving so far.
