Rocker Arm Cover Sealing:
3. Reseal rocker arm cover with gasket 1627340 or apply a continuous bead 3-4 mm in diameter of RTV sealant, such as 1052751 or equivalent, to the sealing flange of the cover. DO NOT USE RTV ON GASKET.
4. Position cover to cylinder head and install screws. Do not slide cover around to align screws as sealing may be compromised. Try to lower cover on to head in aligned position. Alignment dowels cut from 6 mm bolts will allow exact positioning. Torque to 5 Nm (4 ft. lbs.).
5. Install PCV valve to cover grommet.
6. Position accelerator cable bracket to intake manifold and secure with 2 screws (25 Nm, 20 ft. lbs.).
7. Connect accelerator, transmission downshift, and cruise control cables to throttle body.
8. Position spark plug wire retainers over cover bolt studs and connect wires to plugs. Firing order of this engine is such that cylinders 5 and 7 fire in sequence. Therefore, care should be exercised to see that these wires are isolated from each other as much as possible to prevent cross-firing. Specifications
