HYDRAULIC LASH ADJUSTERS | CHECK, REMOVAL AND INSTALLATION CHECK (Refer to illustration 6.1)REMOVAL (Refer to illustration 6.4)
- Check the hydraulic lash adjusters for freeplay by inserting a small wire through the air bleed hole in the rocker arm while lightly pushing the check ball down (see illustration).
- While lightly holding the check ball down, move the rocker arm up and down to check for freeplay. There should be a small amount of movement. If there is no freeplay, replace the adjuster with a new unit.
- Remove the valve cover(s) (see Section 4) and the rocker arm shaft components (see Section 5).
- Pull the hydraulic lash adjuster(s) out of the rocker arm(s) (see illustration). Note: Be sure to label each rocker arm and adjuster and place them in a partitioned box or something suitable to keep them from getting mixed with each other.
- Installation is the reverse of removal.
INTAKE MANIFOLD | REMOVAL AND INSTALLATION REMOVAL (Refer to illustration 7.13)
- Relieve the fuel system pressure (see Chapter 4).
- Disconnect the cable from the negative terminal of the battery.
- Drain the cooling system (don't forget to drain the cylinder block) (see Chapter 1).
- Remove the air cleaner-to-throttle body inlet hose (see Chapter 4).
- Remove the spark plug wires and distributor cap. Be sure to mark the spark plug wires for proper reinstallation (see Chapter 1).
- Remove the throttle cable and transaxle kickdown linkage (see Chapter 4 and 7B).
- Remove the Idle Speed Control (ISC) motor and throttle position sensor (TPS) electrical connectors from the throttle body.
- Remove the EGR tube flange from the air intake plenum.
- Label and detach any vacuum liens from the throttle body.
- Detach the fuel lines from the fuel rail (see Chapter 4).
- Remove the throttle body, air intake plenum and the fuel injectors (see Chapter 4).
- Label and remove any remaining hoses, wires or cables attached to the intake manifold or its components.
- Loosen the manifold mounting bolts/nuts in 1/4-turn increments until they can be removed by hand. Loosen the outer bolts first, then the inner bolts (see illustration).
- The manifold will probably be stuck to the cylinder heads and force may be required to break the gasket seal. Caution: Don't pry between the manifold and the heads or damage to the gasket sealing surfaces may occur, leading to vacuum leaks.
