Procedure

1. 1

   Remove intake manifold assembly
   Disconnect all vacuum lines, PCV hoses, and electrical connectors from intake manifold. Label each connection. Remove throttle body connections. Remove all intake manifold mounting bolts working from outside to inside in reverse of tightening sequence. Carefully lift intake manifold assembly straight up and away from engine. Inspect manifold gaskets and replace if damaged. Cover intake ports with clean rags to prevent debris entry.

3. 3

   Inspect and document valve train
   With valve cover removed, visually inspect all rocker arms, valve springs, and visible cam lobes for wear or damage. Take photographs of rocker arm positions for reference. Use borescope if available to inspect lifter bores. Verify which lifter requires replacement by checking for collapsed lifter, excessive play, or visible damage. Confirm camshaft is at a safe rotation position with cam lobe pointing away from the lifter to be removed.
   ℹ️If multiple lifters show damage, this single-lifter procedure is insufficient - consult full lifter replacement procedure.
4. 4

   Position camshaft and secure timing
   Rotate crankshaft by hand (using 22mm socket on crankshaft pulley bolt) to position cylinder of failed lifter at TDC on compression stroke (both valves closed). Install camshaft holding tool on rear of affected camshaft to prevent rotation. Verify cam lobe for the affected lifter is pointing away from lifter (on base circle). Mark cam phaser position relative to camshaft with paint pen for reference.
   ⚠Do not rotate engine using camshaft bolts - always rotate by crankshaft pulley only.
5. 5

   Remove rocker arm assembly
   For the affected cylinder, loosen and remove the rocker arm shaft bolts or individual rocker arm bolts (depending on which lifter is being replaced). If removing rocker shaft assembly, loosen bolts evenly in reverse sequence to prevent binding. Lift rocker arm assembly straight up and place on clean surface in organized manner. Keep all components in order for reinstallation. Inspect rocker arm roller and valve tip contact surfaces for wear.

6. 6

   Remove valve spring retainer (if necessary)
   If lifter cannot be accessed due to valve spring interference, use valve spring compressor tool designed for overhead cam engines. Carefully compress valve spring just enough to relieve tension on retainer. Remove valve spring retainer locks using magnetic tool. Slowly release spring compressor tension. Remove retainer and set aside in organized manner. Keep all components for affected valve together.
   ⚠️Valve springs are under significant tension. Ensure valve spring compressor is properly seated before compressing. Flying valve spring components can cause serious injury.
7. 7

   Extract failed lifter
   Using magnetic lifter removal tool, carefully extract the failed lifter from its bore. Lifter should slide out with moderate resistance - if stuck, apply light penetrating oil around lifter body and wait 15 minutes. Rotate lifter gently while pulling if needed. Once removed, inspect lifter bore for scoring, debris, or damage. Clean bore thoroughly with lint-free cloth. Inspect removed lifter for wear patterns, collapsed hydraulics, or roller damage to confirm failure mode.
   ⚠Do not use excessive force - damaged lifter bore will require cylinder head replacement.
8. 8

   Prepare and install new lifter
   Remove new lifter from packaging and inspect for shipping damage. Prime new hydraulic lifter by submerging in clean engine oil and manually compressing plunger 10-15 times until no air bubbles emerge. Coat lifter body thoroughly with assembly lube or fresh engine oil. Ensure lifter bore is completely clean and dry. Install new lifter into bore by hand, ensuring it slides in smoothly without binding. Lifter should sit fully seated in bore with roller facing correct direction (toward cam lobe).
   ℹ️New lifter must be properly primed to prevent valve train noise and potential damage during initial startup.
9. 9

   Reinstall valve spring components (if removed)
   If valve spring was disassembled, place valve spring retainer back onto valve spring. Using valve spring compressor, compress spring enough to install retainer locks. Carefully seat both halves of retainer locks in valve stem groove. Slowly release spring compressor while ensuring locks remain seated. Tap valve stem tip gently with plastic mallet to verify locks are fully seated. Verify retainer and locks are secure before proceeding.
   ⚠Improperly seated valve locks will cause valve drop and catastrophic engine damage.
10. 10

    Reinstall rocker arm assembly
    Apply light coat of engine oil to rocker arm shaft or mounting points. Position rocker arm assembly back onto cylinder head, ensuring correct orientation. Verify cam lobe is still on base circle (pointing away from lifter). Install rocker arm shaft bolts or individual rocker arm bolts finger-tight first. Tighten rocker arm bolts to specification in proper sequence (inside to outside), ensuring even tightening to prevent binding. Verify rocker arm rotates freely on shaft and contacts valve tip squarely.

    Verify valve train operation
    With camshaft still locked, manually check rocker arm movement by pressing down on valve spring side - should have slight spring resistance. Rotate crankshaft slowly by hand one complete revolution while observing valve train movement. Verify smooth operation without binding, unusual noise, or interference. Check that all rocker arms move appropriately as camshaft rotates. Remove camshaft holding tool only after verifying proper operation.
    ⚠Stop immediately if any binding or unusual resistance is felt during rotation - indicates misassembly.
12. 12

    Reinstall valve cover
    Install new valve cover gasket onto valve cover - ensure gasket is properly seated in all grooves. Apply small dab of RTV sealant at front corners where cylinder head meets timing cover (factory critical areas only). Position valve cover onto cylinder head, aligning all bolt holes. Install valve cover bolts finger-tight initially. Tighten valve cover bolts to specification in proper sequence (center outward in crisscross pattern) to ensure even gasket compression.

    Reinstall intake manifold
    Remove protective rags from intake ports. Install new intake manifold gaskets onto cylinder heads - ensure proper orientation with alignment tabs. Carefully lower intake manifold assembly onto engine, guiding all mounting posts into position. Install all intake manifold bolts finger-tight first. Tighten intake manifold bolts to specification in proper sequence (inside to outside in crisscross pattern). Reconnect all vacuum lines, PCV hoses, and electrical connectors according to documentation from disassembly.

    Reinstall ignition system and complete assembly
    Reinstall all ignition coils with fresh dielectric grease on spark plug boots. Reconnect all ignition coil electrical connectors. Install new oil filter and refill engine with 7.5 quarts of Motorcraft 0W-20 full synthetic oil. Reinstall engine cover. Reconnect negative battery cable. Double-check all connections, ensure no tools or rags remain in engine compartment.
    ℹ️Do not start engine yet - proceed to verification steps first.

Reassembly

1. All torque specifications must be followed exactly as listed - over-tightening valve train components causes premature wear
2. New gaskets must be used for intake manifold and valve cover - reused gaskets will leak
3. Tightening sequences for intake manifold and valve cover are critical for even sealing
4. Allow RTV sealant to set for 15 minutes before starting engine if used
5. Verify oil level on dipstick shows FULL after refilling - add oil if necessary

Verification

• Turn ignition to ON position (do not start) and verify no warning lights beyond normal self-test appear
• Check for fuel odors indicating disturbed fuel connections - repair before starting
• Start engine and immediately monitor oil pressure gauge - should show pressure within 5 seconds
• Listen for valve train noise - some lifter ticking for first 30-60 seconds is normal as new lifter pumps up, but should quiet down
• Allow engine to idle for 5 minutes while monitoring for oil leaks around valve cover and intake manifold
• Check for vacuum leaks by listening for hissing sounds around intake manifold
• Rev engine gently to 2000 RPM several times - valve train noise should not increase
• After engine reaches operating temperature, verify no coolant or oil leaks are present
• Test drive vehicle and monitor for unusual engine noises, vibrations, or check engine light
• Recheck oil level after test drive and top off if necessary - new lifter may retain small amount of oil
• Monitor engine for first 100 miles - persistent lifter noise indicates improper installation or additional failed lifters
