The 5.4L 3-valve engine lash adjuster and camshaft design has been modified for the 2005 model year (MY). Do not use 2005 MY parts when servicing a 2004 MY engine, or 2004 MY parts when servicing a 2005 MY engine. If parts are intermixed during a service repair, the engine may exhibit noises on affected cylinders and engine damage may result.
Order and install parts for the correct model year engine. The following Inspection Procedure can also be used to visually confirm the application of a part.
|NOTE:||THE ENGINE MODEL YEAR SHOULD BE CONFIRMED BY CHECKING THE ENGINE TAG LOCATED ON THE VALVE COVER. A 2004 MY ENGINE WILL HAVE CODE 4G-692-AA AND A 2005 MY ENGINE WILL BE IDENTIFIED AS 5G-692-AA.|
2004 and 2005 MY camshafts can be visually identified by the location of the variable cam timing phaser (VCT) pin notch in relation to the machining lug, as seen on the end of the camshafts (Figures 1-2).

2004 and 2005 MY lash adjusters can be visually identified by the presence or lack of an identification groove cut into the lash adjuster boss (Figure 3). The 2005 MY parts will have this identification groove cut into the boss, while the 2004 MY parts will not.
