Some 2011-2013 Ford E-Series vans equipped with a 5.4L 2V or 6.8L 2V engine and built on or before 11/12/2012 may exhibit excessive oil consumption, where 1 quart of oil is consumed at less than 3,000 miles.

Naturally, diagnose as needed, but likely the cause is worn valve stem seals. Ford suggests pulling the heads (or pulling the engine, which may be easier in a van) and replacing the seals.

Parts needed for the job include the following:
