15. Apply silicone rubber sealer (D6AZ−19562−A or equivalent) to the intersection of the cylinder block
assembly and head assembly at four corners as illustrated.
When using silicone rubber sealer, assembly must occur within 15 minutes after sealer application.
After this time, the sealer may start to set−up and its sealing effectiveness may be reduced. In high
temperature/humidity conditions, the RTV will start to skin over in about 5 minutes.
16. Install the front intake manifold seal and rear intake manifold seal, then secure them with retaining
features.
17. Position the intake manifold gaskets in place and insert the locking tabs over the tabs on the cylinder
head gaskets.
18. Apply silicone rubber sealer over the gasket in the same places as in Step 14.
19. Carefully lower the intake manifold into position on the cylinder block and cylinder heads to prevent
smearing the silicone sealer and causing gasketing voids.
20. Install the retaining bolts. Tighten in two stages, using the sequence illustrated, first to 11 ft. lbs., then
to 18 ft. lbs.
21. If installing a new manifold, install fuel supply rail and injectors. Refer to the necessary service
procedures.
22. Install #3 cylinder intake valve pushrod. Apply oil to pushrod and fulcrum prior to installation. Rotate
the crankshaft to place the lifter on the heel position or base circle of camshaft. Tighten to 8 ft. lbs. to
seat fulcrum in cylinder head. Final bolt torque is 5 ft. lbs.
23. Install valve covers, fuel injector harness, throttle body assembly, hose and electrical connections.
24. If equipped with distributor ignition, install the distributor assembly, using the matchmarks made
earlier to insure correct alignment. Install the distributor cap and spark plug wires.
25. If equipped with distributorless ignition, install the coil pack then install the spark plug wires to their
original locations.
26. Install coolant hoses. Connect all vacuum lines. Reconnect fuel lines. Install fuel line safety clips.
27. Fill and bleed cooling system. If any engine coolant accidentally spilled into the engine while the
intake was off, change engine oil and filter.
28. Install air cleaner hose. Connect battery ground cable. Start engine and check for coolant, oil, fuel and
vacuum leaks.
