Disassembly

  1. Install Valve Spring Compressor Tool T94T-6513-AH.

  1. NOTE: It may be necessary to strike the valve stem end with a plastic-tipped hammer to loosen the valve spring retainer keys (6518).

    Remove the valve spring retainer keys, rotators and the valve springs (6513).

  1. Remove the valves.

  1. Remove the valve stem seals (6571).

  1. Remove the intake manifold cover retaining bolts.

  1. NOTE: Carefully remove the intake manifold cover using Rotunda Quick Blade Release Cold Knife 163-00005 or equivalent between the intake manifold cover and the cylinder head to break the RTV sealant. Be careful not to bend intake manifold cover.

    Remove the intake manifold cover.

  1. Remove the injection control pressure sensor and discard O-ring (left cylinder head only).

  1.  CAUTION: Tap Pilot must be used or damage to cylinder head injector bore will result.

    Remove fuel injector sleeves if cylinder head is to be cleaned with solvents. Insert Rotunda Injector Sleeve Tap 014-00934 and Rotunda Injector Sleeve Tap Pilot 014-00934 or equivalents into fuel injector sleeve and tighten 1-1/2 - 2 turns. Attach Slide Hammer T50T-100-A to Rotunda Injector Sleeve Tap 014-00934 or equivalent and remove fuel injector sleeve from fuel injector bore.

  1. The intake valves (6507) can be identified by the dimple in the center of the intake valve head.

    Inspect valve for evidence of burning, warping, scuffing or bending. Minor pits, grooves, etc., may be removed. Discard valves that are severely damaged, if face runout cannot be corrected by refinishing, or if stem clearance exceeds specifications. Refer to Specifications at the end of this section.

    Discard any worn or damaged valve train components.

Assembly

  1. Install the valve stem seals.

  1. Install the valve springs and rotators.

  1. Install Valve Spring Compressor Tool T94T-6513-AH.

  1. Compress the valve springs and install the valve spring retainer keys.

  1. Remove the valve spring compressor tool.

  1. Use Rotunda Injector Sleeve Brush 014-00934 or equivalent to clean the injector bores of any sealant residue and also to ensure a good seating surface for the fuel injector O-rings. Remove any debris from the fuel injector bores.

  1. If removed, install fuel injector sleeves using Rotunda Injector Sleeve Replacer 014-00934 or equivalent. Apply Threadlock® 262 (E2FZ-19554-B) or equivalent meeting Ford specification WSK-M2G351-A6 to the fuel injector sleeves as shown. Using a rubber mallet, tap on tool to seat fuel injector bore. Remove tool from fuel injector sleeve and clean any sealant residue from fuel injector bore.

  1. Apply Silicone Rubber F4AZ-19562-B or equivalent meeting Ford specifications ESE-M4G195-A or WSE-M4G323-A1 to the intake manifold cover mating surfaces.

  1. Install the intake manifold cover.

  1. Install the intake manifold cover retaining bolts. Tighten bolts to 24 Nm (18 lb-ft).

  1. Remove the cylinder head (6049) from the holding fixture.

  1. NOTE: Apply Threadlock® and Sealer EOAZ-19554-AA or equivalent meeting Ford specification WSK-M2G315-A5 to threads of injection control pressure sensor prior to installation.

    Install the injection control pressure sensor with a new O-ring. Tighten injection control pressure sensor to 29 Nm (21 lb-ft).
