1. Remove the cam chain (see page 6-18).
2. Hold the exhaust camshaft with an open-end
wrench, then loosen the variable valve timing
control (VTC) actuator mounting bolt and the
exhaust camshaft sprocket mounting bolt.
3. If the VTC actuator is reused, do these steps. –1 Remove the intake camshaft, and seal theadvance holes and retard holes in the No. 1
camshaft journal with tape (see step 6 on page
6-11).
–2 Punch a hole in the tape over one of the advance holes (see step 7 on page 6-11).
–3 Apply air to the advance hole to release the lock (see step 8 on page 6-11).
–4 Remove the tape from the No. 1 camshaft journal.
4. Remove the VTC actuator and the exhaust camshaft sprocket. 1. Install the variable valve timing control (VTC)
actuator and exhaust camshaft sprocket.
NOTE: Install the VTC actuator to unlock position.
2. Apply new engine oil to the threads of the VTC actuator mounting bolt and the exhaust camshaft
mounting bolt, then install them.
3. Hold the exhaust camshaft with an open-end wrench, then tighten the mounting bolts.
4. Hold the exhaust camshaft with an open-end wrench, and turn the VTC actuator clockwise until
you hear it click. Make sure to lock the VTC actuator
by turning it.
5. Install the cam chain (see page 6-21).
