1. CAUTION: The gasket sealing surfaces on the cylinder head and cylinder block must be clean. For additional information, refer to Cylinder Heads — 5.4L in the Removal portion of this section.
CAUTION: The use of sealing aids (aviation cement, copper spray, and glue) is not permitted. The gasket must be installed dry.
CAUTION: The new gasket has a film coating which is crucial to the gasket's ability to seal properly. Do not scratch the gasket.
NOTE: The RH head gasket is shown; the LH head gasket is similar.
Install the head gasket over the dowel pins.
2. CAUTION: Cylinder head machining or milling is not authorized by the Ford Motor Company. Cylinder head flatness must be within 0.0254 mm (0.001 in) across a 38.1 mm (1.5 in) square area.
CAUTION: The gasket sealing surfaces on the cylinder head and cylinder block must be clean. For additional information, refer to Cylinder Heads — 5.4L in the Removal portion of this section.
CAUTION: The use of sealing aids (aviation cement, copper spray, and glue) is not permitted. The gasket must be installed dry.
CAUTION: Do not allow the dowels to scratch the sealing surface of the cylinder head during cylinder head installation.
NOTE: The new cylinder head bolts must be lightly oiled with a rag, and allowed to drain for a few minutes prior to installation.
NOTE: The RH cylinder head is shown; the LH cylinder head is similar.
Install the cylinder head on the dowels and the head gasket. Loosely install new bolts.

18. CAUTION: Rotate the crankshaft counterclockwise only. Do not rotate past position shown or severe piston and valve damage can occur.
NOTE: The number one piston is at top dead center (TDC) when the stud on the engine block fits into the slot in the handle of the special tool.
Position the crankshaft so the number one cylinder is at TDC with the special tool.
19. Remove the Crankshaft Holding Tool.
20. NOTE: The crankshaft sprockets are identical. They may only be installed one way. Refer to the following illustration for the correct crankshaft sprocket installation.
If removed, install the LH and the RH crankshaft sprockets.
21. Position the lower end of the LH (inner) timing chain on the crankshaft sprocket, aligning the timing mark on the outer flange of the crankshaft sprocket with the single copper (marked) link on the chain.

25. Position the lower end of the RH (outer) timing chain on the crankshaft sprocket, aligning the timing mark on the sprocket with the single copper (marked) chain link.
26. NOTE: The lower half of the timing chain must be positioned above the tensioner arm dowel.
NOTE: If necessary, use the Camshaft Alignment Set to adjust the camshaft sprocket slightly to obtain timing mark alignment.
Position the RH timing chain on the camshaft sprocket. Make sure the camshaft sprocket timing mark is positioned between the two copper (marked) chain links.
27. Position the RH timing chain tensioner arm on the dowel pin and install the RH timing chain tensioner.
28. Remove the retaining clip from the RH timing chain tensioner.
29. As a post-check, verify correct alignment of all timing marks.

30. Install the special tool between the valve spring coils to prevent valve stem seal damage.
31. NOTE: Lubricate the camshaft roller followers using clean engine oil.
NOTE: Position the cam lobe away from the camshaft roller follower location prior to installing each camshaft roller follower.
Install the camshaft roller followers. 1. Install the special tool. 2. Compress the valve spring. 3. Install the camshaft roller followers in their original locations.
32. Remove the special tool.
33. CAUTION: When installing the spark plugs, use care not to exceed the recommended torque.
Install the eight spark plugs.
� Tighten the spark plugs to 18 Nm (13 lb-ft).
34. Install the crankshaft sensor ring on the crankshaft.

35. NOTE: If the front cover is not secured within four minutes, the sealant must be removed and the sealing area cleaned. To clean the sealing area, use silicone gasket remover and metal surface prep. Follow the directions on the packaging. Failure to follow this procedure can cause future oil leakage.
Apply a bead of silicone gasket and sealant along the cylinder head-to-cylinder block surface and the oil pan-to-cylinder block surface, at the locations shown.
36. Install a new engine front cover gasket on the engine front cover. Position the engine front cover. Install the fasteners finger-tight.
37. Tighten the engine front cover fasteners in sequence in three stages. Stage 1: Tighten fasteners 1 through 5 to 25 Nm (18 lb-ft). Stage 2: Tighten fasteners 6 and 7 to 48 Nm (35 lb-ft). Stage 3: Tighten fasteners 8 through 15 to 48 Nm (35 lb-ft).
