Cylinder Head - LH: Installation

WARNING: This page is about a different car, the 2005 Ford Pickup, 2005 Ford F550 Super Duty, 2005 Ford F450 Super Duty, and 2005 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

    All vehicles 

    CAUTION: Install new D-ring seals on the crankcase-to-head tube. It requires several hours after installation for the D-ring seals to relax back to their original size. If the tube assembly is installed before the D-ring seals have relaxed, damage to the D-ring seals can occur.
    NOTE: Late build shown, early build similar.

  1. Install new D-ring seals on the crankcase-to-head tube assemblies.
    2. NOTE: Use care to avoid scratching the blue compound on the cylinder head gasket. Install the gasket with the part number facing upward and verify the 5 top holes and head gasket push rod holes line up.
  2. Install the dowels and the cylinder head gasket.
    3. NOTE: The back two cylinder head bolts cannot be installed into the head in vehicle. Lightly lubricate the threads of 2 new cylinder head bolts with clean engine oil. Position these bolts in the head and secure them in position, so they will clear the cylinder block deck as the head is installed.
    NOTE: Position the fuel lines in place before the cylinder head is installed.

    5. CAUTION: To prevent engine damage, keep the push rods in the order in which they were removed. Install all push rods back in their original positions.
    NOTE: Higher mileage engines require push rods to be cleaned so the copper-colored end of the push rod can be identified.
    NOTE: If a push rod has been replaced, it may not have a copper-colored end and can be installed with either end up.

  7. Install the rocker arm assemblies and eight bolts.
    8. CAUTION: Using too much engine oil on the threads of the cylinder head bolts can cause damage to the threads and poor sealing. Using anti-seize compounds, grease or any other lubricants other than engine oil on the cylinder head bolt threads can affect the true torque value of the bolts.
    CAUTION: Make sure the insulation blanket is not damaged (torn, cracked or fabric separated from the metallic skin) when installing the lower rear cylinder head bolt. If the insulation blanket is damaged, the entire blanket must be replaced.
    NOTE: It may be necessary to slightly compress or deform the insulation blanket to gain tool clearance to install the lower rear cylinder head bolt.
    NOTE: Lightly lubricate the new cylinder head bolt threads and flanges with clean engine oil.
