Replacing Camshaft & Valve Lifters On Ford, Mercury and Lincoln?

The procedure is similar for Ford Crown Victoria, Mercury Grand Marquis, Lincoln Town Car.          

The procedure is as follows:----

Camshaft & Valve Lifters

REMOVAL & INSTALLATION instructions are as follows:-----

1. If equipped with air suspension, the air suspension switch, must be turned to the OFF position before raising the vehicle.
2. Properly relieve the fuel system pressure.
3. Drain the engine oil
4. Remove or disconnect the following:
   
   NOTE

   The front lower bolt on the power steering pump will not come all the way out.
   
   
   
   
   Negative battery cable

   Fan blade and fan shroud assembly

   Fuel supply and return lines from the fuel injection supply manifold

   Windshield wiper governor (module) assembly from the vehicle

   Engine air cleaner outlet tube

   Accessory drive belt

   Ignition wires from the spark plugs

   Ignition wire brackets from the cylinder head cover studs

   2 bolts retaining the ignition wire separator to the ignition coil brackets and the bolt retaining the air conditioning pressure line to the right-hand ignition coil bracket.

   Connectors from both ignition coils and the Crankshaft Position (CMP) sensor

   Ignition coils with brackets attached

   Electrical connector from the alternator and at the power distribution box

   Water pump pulley

   Positive battery cable at the power distribution box

   Bolt from the positive battery cable bracket located on the right-hand cylinder head

   Fuel vapor hose from the EVAP canister purge valve and position the positive battery cable aside

   Positive Crankcase Ventilation (PCV) valve from the cylinder head cover and position aside

   Engine/transmission harness connector from the bracket on the power brake booster

   Crankshaft Position (CKP) sensor and air conditioning clutch harness connectors

   Bolts retaining the power steering pump to the cylinder block and wire the pump aside
   
   
   
   
   Oil pan

   Crankshaft pulley bolt and washer and crankshaft pulley

   Engine oil filter

   Power steering control valve actuator and oil pressure sensor

   Oil filter adapter

   Cylinder head covers

   Engine front cover

   Timing chains
5. Rotate the crankshaft counterclockwise no more than 45 degrees from Top Dead Center (TDC) to ensure that all pistons are below the top of the engine block deck face.
6. Install a valve spring compressor under the camshaft and on top of one of the valve spring retainers.
7. Install Valve Spring Spacer T91P-6565-AH between the valve spring coils. Be sure that the valve being compressed is on its base circle. Compress the valve spring and remove the rocker arm. Repeat the procedure until all rocker arms are removed.
8. If required, pull the lash adjusters out of their bores in the cylinder head. Note their locations; they must be installed in the same bore they were removed from.
   
   NOTE

   Do not mix the camshaft bearing caps. Note the camshaft bearing cap locations for installation.
9. To remove each camshaft, unfasten the 14 bolts retaining the camshaft bearing caps (cluster assemblies) to the cylinder head. Tap upward on the camshaft bearing caps at points near the upper bearing halves and gradually lift the camshaft bearing cap clusters from the cylinder head.
10. Repeat the removal procedure for the opposite cylinder head.
11. Remove the camshaft straight upward to avoid bearing damage.
12. Clean and inspect the camshafts and related components for unusual wear or damage.

To install:

1. Clean and inspect the cylinder head covers, engine front cover and cylinder head sealing surfaces.
2. Apply clean engine oil to the camshaft journals and lobes. Position the camshafts on the cylinder heads.
3. Install and seat the camshaft bearing cap cluster assemblies. Install and hand start the retaining bolts. Tighten the camshaft cluster retaining bolts in sequence to 89 inch lbs. (10 Nm). Be sure to tighten each camshaft bearing cap cluster individually.
   
   NOTE

   Each camshaft bearing cap cluster assembly is tightened individually.
4. Loosen the camshaft bearing cap cluster retaining bolts approximately 2 turns or until the heads of the bolts are free. Tighten all bolts, again in sequence, to 89 inch lbs. (10 Nm).
5. Repeat the camshaft bearing cap installation for the opposite cylinder head.
   
   NOTE

   The camshafts should turn freely but with a slight drag.
6. Check camshaft end-play as follows:
   1. Step 1: Install a dial indicator on the front of the engine. Position it so the indicator foot is resting on the camshaft sprocket bolt or the front of the camshaft.
   2. Step 2: Push the camshaft toward the rear of the engine and zero the dial indicator.
   3. Step 3: Pull the camshaft forward and release it. Specified end-play is 0.0901-0.006 inch (0.025-0.190mm).
   4. Step 4: If end-play is too tight, check for binding or foreign material in the camshaft thrust bearing. If end-play is excessive, check for worn camshaft thrust plate and replace the cylinder head, as required.
   5. Step 5: Remove the dial indicator.
7. If removed, install the lash adjusters in their original positions.
8. If necessary, install Camshaft Positioning Tools T92P-6256-A on the flats of the camshafts and install the spacers and camshaft sprockets. Install the bolts and washers and tighten to 30 ft. lbs. (40 Nm), then tighten an additional 90 degrees.
9. Install a valve spring compressor under the camshaft and on top of the valve spring retainer.
10. Install Valve Spring Spacer T91P-6565-AH between the valve spring coils. Be sure that the valve being compressed is on its base circle. Compress the valve spring and install the rocker arm. Repeat the procedure until all rocker arms are installed.
11. Rotate the crankshaft clockwise 45 degrees to position the crankshaft at Top Dead Center (TDC).
    
    NOTE

    The crankshaft must only be rotated in the clockwise direction and only as far as TDC.
12. Install or connect the following:
    
    
    Timing chains

    Engine front cover

    Cylinder head covers. Tighten the cylinder head cover bolts to 89 inch lbs. (10 Nm).

    Power steering control valve actuator connector

    Oil pressure sensor harness connector
13. Apply silicone sealer to the crankshaft keyway
14. Install the crankshaft pulley and tighten the bolt as follows:
    1. Step 1: Tighten to 66 ft. lbs. (90 Nm).
    2. Step 2: Loosen one complete turn.
    3. Step 3: Tighten to 37 ft. lbs. (50 Nm).
    4. Step 4: Tighten an additional 90 degrees.
15. Install or connect the following:
    
    
    Engine oil pan

    Power steering pump on the engine and the 4 retaining bolts. Tighten the bolts to 18 ft. lbs. (25 Nm).

    Air conditioning clutch and CKP sensor

    Evaporative emission canister purge valve harness connector

    Engine/transmission harness connectors on the power brake booster retaining bracket

    PCV valve to the right-hand cylinder head cover

    Positive battery cable harness on the right-hand cylinder head

    Bolt retaining the battery cable bracket to the cylinder head

    Evaporative emission hose to the canister purge valve

    Positive battery cable at the power distribution box

    Water pump pulley and tighten the bolts to 18 ft. lbs. (25 Nm)

    Ignition coil brackets and ignition wires to the engine front cover. Tighten the retaining nuts to 18 ft. lbs. (25 Nm).

    Harness connectors to the ignition coils and the CMP sensor

    Air conditioning pressure line on the right-hand ignition coil bracket and the retaining bolt

    Ignition wires to the spark plugs and the brackets onto the cylinder head cover studs

    Accessory drive belt

    Windshield wiper governor

    Fuel supply and return lines

    Fan and shroud assembly

    Negative battery cable
16. Fill the engine cooling system.
17. Fill the crankcase.
18. If equipped with air suspension, turn the air suspension switch to the ONposition.
19. Start the engine and check for leaks.
20. Road test the vehicle and check for proper engine operation.

This details will help.
