Is there any updated information regarding cam timing on Ford 4.0L engines?
Some service manual information regarding camshaft timing for 1997-2003 Ford 4.0L VIN E engines is erroneous.
Ford published the correct information in a service bulletin dated May 2001 as part of a cam chain guide campaign. Subsequent year manuals should have the updated information depending on their source. Basically, the left and right side camshafts require 180° difference in phasing. However, the engine will run if both banks are timed in the same position. When correctly timed, the right bank camshaft valve timing should be 180° from the position of the left bank camshaft.
