Camshaft - RH: Installation

WARNING: This page is about a different car, the 2014 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.

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 in illustration.

NOTE: The crankshaft must remain in the free wheeling position (crankshaft dowel pin at 9 o'clock) until 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.
NOTE: 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 in illustration.

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 in illustration.
- Tighten to 8 Nm (71 lb-in) then an additional 45 degrees.
Loosen the 4 camshaft caps bolts.
Tighten the 4 camshaft caps bolts in the sequence shown in illustration.
- Tighten bolts 8, 9, 10 and 11 to 8 Nm (71 lb-in) then an additional 45 degrees.
NOTE: 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 .

NOTE: The camshaft bearing cap assembly must be secured within 10 minutes of the Gasket Maker application. If the camshaft bearing cap assembly is not secured within 10 minutes, the sealant must be removed and the sealing area cleaned with Motorcraft® Metal Surface Prep.

Apply a 3 mm (0.118 in) bead of sealant to the camshaft bearing cap assembly.
Install the camshaft bearing cap assembly and the 2 bolts.
- Tighten to 8 Nm (71 lb-in) then an additional 45 degrees.
- Remove the excess gasket maker.
Remove the 3 bolts and the RH valve train oil tube.
Rotate the RH camshafts to the TDC position as shown in illustration.
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.
Compress the RH secondary timing chain tensioner and install the Secondary Chain Hold Down to retain the tensioner in the collapsed position.
Assemble the RH VCT assembly, the RH exhaust camshaft sprocket and the RH secondary timing chain.
- Align the colored links with the timing marks.
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.
Install the 2 new RH VCT bolts and tighten in 4 stages.
- Stage 1: Tighten to 40 Nm (30 lb-ft).
- Stage 2: Loosen one full turn.
- Stage 3: Tighten to 25 Nm (18 lb-ft).
- Stage 4: Tighten an additional 180 degrees.
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.
- Make sure the secondary timing chain is centered on the timing chain tensioner guides.
Rotate the crankshaft clockwise 60 degrees to TDC position (crankshaft dowel pin at the 11 o'clock position).
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.

Install the lower LH primary timing chain guide and the 2 bolts.
- Tighten to 10 Nm (89 lb-in).
Install the primary timing chain tensioner arm.
Reset the primary timing chain tensioner.
1. Release the ratchet detent.
2. Using a soft-jawed vise, compress the ratchet plunger.
3. Align the hole in the ratchet plunger with the hole in the tensioner housing and install a suitable lockpin.
NOTE: It may be necessary to rotate the camshafts slightly to remove slack from the timing chain to install the tensioner.

Install the primary timing chain tensioner and the 2 bolts.
- Tighten to 10 Nm (89 lb-in).
- Remove the lockpin.
As a post-check, verify correct alignment of all timing marks.
- There are 48 links in between the RH intake VCT assembly colored link (1) and the LH intake VCT assembly colored link (2).
- There are 35 links in between LH intake VCT assembly colored link (2) and the 2 crankshaft sprocket links (3).
NOTE: 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.
- Tighten to 8 Nm (71 lb-in) then an additional 20 degrees.
