RH camshafts
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.NOTICE: The crankshaft must remain in the freewheeling position (crankshaft dowel pin at 9 o'clock) until after the camshafts are installed and the valve clearance is checked/adjusted. Do not turn the crankshaft until instructed to do so. Failure to follow this process will result in severe engine damage.
Rotate the crankshaft counterclockwise until the crankshaft dowel pin is in the 9 o'clock position.NOTICE: The camshaft seal gaps must be at the 12 o'clock position or damage to the engine may occur.
Position the 4 camshaft seals gaps as shown.NOTE: Cylinder head camshaft bearing caps are numbered to verify that they are assembled in their original positions.
Install the 6 camshaft caps, mega cap, valve train oil tube and the 15 bolts in the sequence shown.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. If valve tappet clearances are not within specification, the clearance must be adjusted by installing new valve tappet(s) of the correct size. For additional information, refer to Valve Clearance Check in this section.NOTE: The Camshaft Holding Tool will hold the camshafts in the TDC position.
Install the Camshaft Holding Tool onto the flats of the RH camshafts.NOTE: It may be necessary to rotate the camshafts slightly, to install the RH secondary timing assembly.
Position the 2 RH VCT assemblies and secondary timing chain onto the camshafts by aligning the holes in the VCT assemblies with the dowel pins in the camshafts.NOTE: The 2 VCT oil control solenoids are removed for clarity.
Compress the RH secondary timing chain tensioner and remove the Secondary Chain Hold Down.LH camshafts
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.NOTICE: The crankshaft must remain in the freewheeling position (crankshaft dowel pin at 9 o'clock) until after the camshafts are installed and the valve clearance is checked/adjusted. Do not turn the crankshaft until instructed to do so. Failure to follow this process will result in severe engine damage.
Rotate the crankshaft counterclockwise until the crankshaft dowel pin is in the 9 o'clock position.NOTICE: The camshaft seal gaps must be at the 12 o'clock position or damage to the engine may occur.
Position the 4 camshaft seals gaps as shown.NOTE: Cylinder head camshaft bearing caps are numbered to verify that they are assembled in their original positions.
Install the 6 camshaft caps, mega cap, valve train oil tube and the 15 bolts in the sequence shown.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. If valve tappet clearances are not within specification, the clearance must be adjusted by installing new valve tappet(s) of the correct size. For additional information, refer to Valve Clearance Check in this section.NOTE: The Camshaft Holding Tool will hold the camshafts in the Top Dead Center (TDC) position.
Install the Camshaft Holding Tool onto the flats of the LH camshafts.NOTE: It may be necessary to rotate the camshafts slightly, to install the LH secondary timing assembly.
Position the 2 LH VCT assemblies and secondary timing chain onto the camshafts by aligning the holes in the VCT assemblies with the dowel pins in the camshafts.NOTE: The 2 VCT oil control solenoids are removed for clarity.
Compress the LH secondary timing chain tensioner and remove the Secondary Chain Hold Down.All camshafts
NOTE: It may be necessary to rotate the camshafts slightly, to align the timing marks.
Install the primary timing chain with the colored links aligned with the timing marks on the VCT assemblies and the crankshaft sprocket.NOTE: It may be necessary to rotate the camshafts slightly to remove slack from the timing chain to install the tensioner.
Install the primary tensioner and the 2 bolts.NOTICE: Do not use excessive force when installing the Variable Camshaft Timing (VCT) oil control solenoid. Damage to the mega cap could cause the cylinder head to be inoperable. If difficult to install the VCT oil control solenoid, inspect the bore and VCT oil control solenoid to ensure there are no burrs, sharp edges or contaminants present on the mating surface. Only clean the external surfaces as necessary.
NOTE: A slight twisting motion will aid in the installation of the VCT oil control solenoid.
NOTE: Keep the VCT oil control solenoid clean of dirt and debris.
Install the LH intake VCT oil control solenoid and the bolt.NOTICE: Do not use excessive force when installing the Variable Camshaft Timing (VCT) oil control solenoid. Damage to the mega cap could cause the cylinder head to be inoperable. If difficult to install the VCT oil control solenoid, inspect the bore and VCT oil control solenoid to ensure there are no burrs, sharp edges or contaminants present on the mating surface. Only clean the external surfaces as necessary.
NOTE: A slight twisting motion will aid in the installation of the VCT oil control solenoid.
NOTE: Keep the VCT oil control solenoid clean of dirt and debris.
Install the RH intake VCT oil control solenoid and the bolt.NOTICE: Only use a 3M™ Roloc® Bristle Disk (2-in white, part number 07528) to clean the engine front cover. Do not use metal scrapers, wire brushes or any other power abrasive disk to clean front cover.
Clean the engine front cover using a 3M™ Roloc® Bristle Disk (2-in white, part number 07528) in a suitable tool turning at the recommended speed of 15,000 rpm.NOTICE: Place clean, lint-free shop towels over exposed engine cavities. Carefully remove the towels so foreign material is not dropped into the engine. Any foreign material (including any material created while cleaning gasket surfaces) that enters the oil passages or the oil pan, may cause engine failure.
NOTICE: Do not use wire brushes, power abrasive discs or 3M™ Roloc® Bristle Disk (2-in white part number 07528) to clean the sealing surfaces of engine block, cylinder heads, and oil pan. These tools can cause contamination that will cause premature engine failure. Remove all traces of the gasket.
NOTICE: Failure to use Motorcraft® 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 7, 8, 15, 17, 18, 21 and 22 must be installed within 4 minutes of the initial sealant application. The remainder of the engine front cover 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® High Performance Engine RTV Silicone to the engine front cover sealing surfaces including the 4 inner bolt bosses.NOTE: Make sure the 2 locating dowel pins are seated correctly in the cylinder block.
