VVT-i engines

7 Remove the throttle body as described in Section 12.

8 Release the clips securing the engine wiring loom to the 2 brackets on the top of the manifold, then disconnect the camshaft position sensor plug and move the loom to one side.

9 Undo the two bolts and release the hose bracket from the manifold (see illustration).

10 Disconnect the brake servo vacuum pipe and the PCV (positive crankcase ventilation) hose from the manifold (see illustration).

11 Undo the three bolts, two nuts, remove the

2 brackets, then remove the intake manifold

(see illustration). Recover the intake manifoldO-ring seals. Release the wiring loom clip as the manifold is removed.

13.6b Remove the intake manifold bolts/ nuts and remove the intake manifold

may include the gasket for the air chamber cover. Unless the engine has covered a high mileage or you suspect a vacuum leak at the mating surfaces, don't unbolt the air chamber cover. If it's necessary to renew the gasket, unbolt the cover, clean the surfaces, position the new gasket and reinstall the cover.

14 Fit a new gasket/O-ring seals, then position the manifold on the cylinder head and refit the nuts/bolts.

15 Tighten the nuts/bolts in three or four equal steps to the torque listed in this Chapter's Specifications. Work from the centre out towards the ends to avoid warping the manifold.

16 Refit the remaining parts in the reverse order of removal.

17 Before starting the engine, check the throttle linkage for smooth operation.

18 Run the engine and check for coolant and vacuum leaks.
