How to replace Valve Covers on Ford Truck 5.4L Engine?



The procedure is similar for both ford and Lincoln car models:-----

Ford Truck 5.4L engine Valve Cover removal procedure is as follows.
Its for

F150 1/2 ton P/U 2WD/ 4WD
F250 Super Duty P/U 2WD/4WD
F350 Super Duty P/U 2WD/4WD
F450 Super Duty P/U 2WD/4WD

And Lincoln Mark LT car models.

Valve Covers Removal and Installation For 
5.4L Engine
Left Side
  1. Remove the air cleaner intake pipe.
  2. Remove the left side ignition coils.
  3. Remove the oil level indicator and tube.
  4. Remove the bolt and the nut and position the power steering reservoir and bracket assembly aside.
  5. Disconnect the quick connect couplings and remove the positive crankcase ventilation (PCV) tube.
  6. Disconnect the intake manifold vacuum tube hose from the brake booster.
  7. Disconnect the intake manifold vacuum tube from the support bracket and the valve cover stud.
  8. Disconnect the radio ignition interference capacitor electrical connector.
  9. Disconnect the variable camshaft timing (VCT) solenoid electrical connector and the wiring harness retainers.
    WARNING
    Do not use metal scrapers, wire brushes, power abrasive discs or other abrasive means to clean the sealing surfaces. These tools cause scratches and gouges which make leak paths. Use a plastic scraping tool to remove all traces of old sealant.


    NOTE
    The bolts are part of the valve cover and should not be removed.
  10. Loosen the 15 fasteners and remove the left side valve cover and gasket.
  11. Clean the valve cover mating surface of the cylinder head with silicone gasket remover and metal surface prep. Follow the directions on the packaging.
  12. Discard the valve cover gasket. Clean the valve cover gasket groove with soap and water or a suitable solvent.
