NOTICE: During engine repair procedures, cleanliness is extremely important. Any foreign material, including any material created while cleaning gasket surfaces that enters the oil passages, coolant passages or the oil pan, may cause engine failure.
NOTICE: Early build engines have 11 fastener valve covers, late build engines have 9 fastener valve covers. Do not attempt to install bolts in the 2 empty late build valve cover holes or damage to the valve cover will occur.
NOTE: On early build engines, the timing chain rides on the inner side of the RH timing chain guide. Late build engines are equipped with a different design RH timing chain guide that requires the timing chain to ride on the outer side of the RH timing chain guide. For service, all replacement RH timing chain guides will be the late build design.
NOTE: Assembly of the engine requires various inspections/measurements of the engine components (engine block, crankshaft, connecting rods, pistons and piston rings). These inspections/measurements will aid in determining if the engine components will require replacement. For additional information, refer to Engine.
46. NOTICE: The camshafts must remain in the neutral position during installation or engine damage may occur.
NOTE: Coat the camshafts with clean engine oil prior to installation.
Position the camshafts onto the RH cylinder head in the neutral position as shown.
47. NOTE: Cylinder head camshaft bearing caps are numbered to verify that they are assembled in their original positions.
Install the 8 camshaft caps and the 16 bolts.
- Tighten in the sequence shown to 10 Nm (89 lb-in).
48. NOTICE: The camshafts must remain in the neutral position during installation or engine damage may occur.
NOTE: Coat the camshafts with clean engine oil prior to installation.
Position the camshafts onto the LH cylinder head in the neutral position as shown.
49. NOTE: Cylinder head camshaft bearing caps are numbered to verify that they are assembled in their original positions.
Install the 8 camshaft caps and the 16 bolts.
- Tighten in the sequence shown to 10 Nm (89 lb-in).
50. NOTICE: If any components are installed new, the engine valve clearance must be checked/adjusted or engine damage may occur.
NOTE: Use a camshaft sprocket bolt to turn the camshafts.
Using a feeler gauge, confirm that the valve tappet clearances are within specification. For additional information, refer to Valve Clearance Check Adjustments.

59. Install the LH secondary timing chain tensioner and the 2 bolts.
- Tighten to 10 Nm (89 lb-in).
60. NOTE: Use a camshaft sprocket bolt to turn the camshafts.
Rotate the LH camshafts to the TDC position and install the Camshaft Holding Tool on the flats of the camshafts.
61. Assemble the LH VCT assembly, the LH exhaust camshaft sprocket and the LH secondary timing chain.
- Align the colored links with the timing marks.
62. Position the LH secondary timing assembly onto the camshafts.
63. Install the new VCT bolt and the exhaust camshaft bolt and the original washers. Tighten in 4 stages.

- Stage 4: Tighten 90 degrees.
64. Remove the lockpin from the LH secondary timing chain tensioner.
65. Rotate the crankshaft clockwise 60 degrees to the TDC position (crankshaft dowel pin at 11 o'clock).
66. Install the crankshaft timing chain sprocket.
67. Install the primary timing chain with the colored links aligned with the timing marks on the VCT assemblies and the crankshaft sprocket.

- Tighten to 10 Nm (89 lb-in).
70. Install the primary timing chain tensioner arm.
71. Reset the primary timing chain tensioner.
- Rotate the lever counterclockwise.
- Using a soft-jawed vise, compress the plunger.
- Align the hole in the lever with the hole in the tensioner housing.
- Install a suitable lockpin.
72. NOTE: It may be necessary to rotate the crankshaft slightly to remove slack from the timing chain and install the tensioner.
Install the primary tensioner and the 2 bolts.
- Tighten to 10 Nm (89 lb-in).
- Remove the lockpin.
73. As a post-check, verify correct alignment of all timing marks.
74. Inspect the VCT housing seals for damage and replace as necessary.
75. NOTICE: Make sure the dowels on the Variable Camshaft Timing (VCT) housing are fully engaged in the cylinder head prior to tightening the bolts. Failure to follow this process will result in severe engine damage.
Install the LH VCT housing and the 3 bolts.
- Tighten in the sequence shown to 10 Nm (89 lb-in).
76. NOTICE: Make sure the dowels on the Variable Camshaft Timing (VCT) housing are fully engaged in the cylinder head prior to tightening the bolts. Failure to follow this process will result in severe engine damage.

- Tighten in the sequence shown to 10 Nm (89 lb-in).
77. Install the Alignment Pins.
78. NOTICE: Failure to use Motorcraft(R) High Performance Engine RTV Silicone may cause the engine oil to foam excessively and result in serious engine damage.
NOTE: The engine front cover and bolts 17, 18, 19 and 20 must be installed within 4 minutes of the initial sealant application. The remainder of the engine front cover bolts and the engine mount bracket bolts must be installed and tightened within 35 minutes of the initial sealant application. If the time limits are exceeded, the sealant must be removed, the sealing area cleaned and sealant reapplied. To clean the sealing area, use silicone gasket remover and metal surface prep. Failure to follow this procedure can cause future oil leakage.
Apply a 3.0 mm (0.11 in) bead of Motorcraft(R) High Performance Engine RTV Silicone to the engine front cover sealing surfaces including the 3 engine mount bracket bosses.
- Apply a 5.5 mm (0.21 in) bead of Motorcraft(R) High Performance Engine RTV Silicone to the oil pan-to-cylinder block joint and the cylinder head-to-cylinder block joint areas of the engine front cover in 5 places as indicated.
