Refitting

Remove the upper heat shield from the manifold

14.2a Remove the upper bolt retaining the	14.2b Exhaust pipe-to-manifold bolts
brace (top arrow) and slacken the brace to
block bolts (lower arrows)	(arrowed) - VVT-i engines

nuts/bolts retaining the exhaust pipe to the manifold (see illustrations)

3 Where fitted, unbolt the exhaust manifold brace.

4 Where the manifold has an oxygen sensor fitted, trace the wiring from the sensor back to the connector and unplug it.

5 Remove the nuts/bolts and detach the manifold and gasket.

6 Use a scraper to remove all traces of old gasket material and carbon deposits from the manifold and cylinder head mating surfaces. If the gasket was leaking, have the manifold checked for warpage at an automotive machine workshop and resurfaced if necessary.

7 Position a new gasket over the cylinder head studs. Note: The marks on the gasket should face out (away from the cylinder head) and the arrow should point toward the transmission end of the engine.

8 Refit the manifold and thread the mounting nuts/bolts into place.

9 Working from the centre out, tighten the nuts/bolts to the torque listed in this Chapter's Specifications in three or four equal steps.

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

11 Run the engine and check for exhaust leaks.
