Camshaft














Installation

WARNING: Do not smoke, carry lighted tobacco or have an open flame of any type when working on or near any fuel-related component. Highly flammable mixtures are always present and may be ignited. Failure to follow these instructions may result in serious personal injury.

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: Whenever turbocharger air intake system components are removed, always cover open ports to protect from debris. It is important that no foreign material enter the system. The turbocharger compressor vanes are susceptible to damage from even small particles. All components should be inspected and cleaned, if necessary, prior to installation or reassembly.

All camshafts

36. NOTE: Apply clean engine oil to the crankshaft front seal bore in the engine front cover.
Using the Crankshaft Vibration Damper Installer and Front Crankshaft Seal Installer, install a new crankshaft front seal.






37. NOTE: Lubricate the outside diameter sealing surfaces with clean engine oil.
Using the Crankshaft Vibration Damper Installer and Front Cover Oil Seal Installer, install the crankshaft pulley.






38. Using the Strap Wrench, install the crankshaft pulley washer and new bolt and tighten in 4 stages.
- Stage 1: Tighten to 120 Nm (89 lb-ft).

- Stage 2: Loosen one full turn.

- Stage 3: Tighten to 50 Nm (37 lb-ft).

- Stage 4: Tighten an additional 90 degrees.






39. Install the accessory drive belt tensioner and the 3 bolts.
- Tighten to 11 Nm (97 lb-in).






40. Rotate the accessory drive belt tensioner clockwise and install the accessory drive belt.





41. NOTE: Installation of new seals is only required if damaged seals were removed during disassembly of the engine.

NOTE: Spark plug tube seal installation shown, VCT (Variable Camshaft Timing) solenoid seal installation similar.

Using the VCT (Variable Camshaft Timing) Spark Plug Tube Seal Installer and Handle, install new VCT (Variable Camshaft Timing) solenoid and/or spark plug tube seals.





42. 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: If the valve cover is not installed and the fasteners tightened within 4 minutes, the sealant must be removed and the sealing area cleaned. To clean the sealing area, use silicone gasket remover and metal surface prep. Failure to follow this procedure can cause future oil leakage.
Apply an 8 mm (0.31 in) bead of Motorcraft(R) High Performance Engine RTV Silicone to the engine front cover-to-RH cylinder head joints.






43. Using a new gasket, install the RH valve cover and tighten the 11 stud bolts.
- Tighten in the sequence shown to 10 Nm (89 lb-in).






44. 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: If the valve cover is not installed and the fasteners tightened within 4 minutes, the sealant must be removed and the sealing area cleaned. To clean the sealing area, use silicone gasket remover and metal surface prep. Failure to follow this procedure can cause future oil leakage.
Apply an 8 mm (0.31 in) bead of Motorcraft(R) High Performance Engine RTV Silicone to the engine front cover-to-LH cylinder head joints.






45. Using a new gasket, install the LH valve cover and tighten the 10 stud bolts.
- Tighten in the sequence shown to 10 Nm (89 lb-in).






46. Install 3 RH ignition coil-on-plugs and the 3 bolts.
- Tighten to 7 Nm (62 lb-in).






47. Install 3 LH ignition coil-on-plugs and the 3 bolts.
- Tighten to 7 Nm (62 lb-in).






48. NOTE: The cam lobe for the fuel injection pump must be at Bottom Dead Center (BDC) for the fuel injection pump installation.
Using the crankshaft pulley bolt, turn the crankshaft until the fuel injection pump cam lobe is at BDC (Bottom Dead Center).






49. NOTE: Valve cover is removed for clarity.

NOTE: Apply clean engine oil to the fuel injection pump mounting pedestal bore.
Install the fuel injection pump roller tappet.






50. NOTE: Apply clean engine oil to the fuel injection pump mounting plate seal.
Inspect the fuel injection pump mounting plate-to-valve cover gasket and replace if necessary.






51. NOTE: Apply clean engine oil to the fuel injection pump mounting plate O-ring seals.
Inspect the 2 fuel injection pump mounting plate O-ring seals and replace if necessary.






52. NOTE: Apply clean engine oil to the fuel injection pump O-ring seal.
Install the fuel injection pump on the fuel injection pump mounting plate.






53. NOTE: Clean the fuel injection pump bolts and apply Thread Sealant with PTFE to the bolts.

NOTE: Start the fuel injection pump bolts by hand then simultaneously tighten to specifications.

Install the fuel injection pump and the 2 bolts.
- Tighten to 10 Nm (89 lb-in).

- Tighten an additional 45 degrees.






54. NOTE: To install, apply clean engine oil to the threads of the 3 high-pressure fuel tube flare nuts.
Install the high-pressure fuel tube and tighten the 3 flare nuts in the following 3 stages.

- Stage 1: Tighten to 32 Nm (24 lb-ft).

- Stage 2: Wait 10 minutes to minimize pre-stress.

- Stage 3: Tighten to 32 Nm (24 lb-ft).






55. Install the high-pressure fuel tube bracket nut.
- Tighten to 8 Nm (71 lb-in).






56. Attach the wiring harness retainers to the RH valve cover and stud bolt.

57. Connect the 3 RH ignition coil-on-plug electrical connectors.





58. Connect the RH VCT (Variable Camshaft Timing) solenoid electrical connector and attach the 2 wiring harness retainers.





59. NOTICE: If the engine is repaired or replaced because of upper engine failure, typically including valve or piston damage, check the intake manifold for metal debris. If metal debris is found, install a new intake manifold. Failure to follow these instructions can result in engine damage.

NOTE: Make sure the fuel rail wiring harnesses are routed correct.

NOTE: Installing the 2 long bolts first will aid in installing the intake manifold.

Using new intake manifold, coolant crossover and thermostat housing gaskets, install the intake manifold and the 12 bolts.
