Some 2012 Ford Focus 2.0L GDI (gasoline direct injection) engines may exhibit an oil leak at the rear upper exhaust manifold stud area.

  1. Remove the No. 4 exhaust manifold nut and stud, and discard.
  2. Use Motorcraft Metal Brake Parts Cleaner and clean the stud hole in the cylinder head.
  3. Apply Loctite 592 PST Thread Sealant liberally to the new stud threads.
  4. Install the stud into the cylinder head and tighten the stud to 11-14 ft.-lbs.
  5. Install the nut and tighten to 41 ft.-lbs.
