Removal
1. Remove the intake manifold.
2. Remove the timing chains.
3. Remove the LH exhaust manifold.
4. Disconnect the radio ignition interference capacitor and remove the engine control sensor wiring.
5. Remove the bolt and the oil level indicator tube.
6. Inspect the O-rings, replace as necessary.
7. Remove the bolts and the LH timing chain guide.
8. NOTE: It will be necessary to support the number eight bolt. Pull the bolt out far enough so it does not contact the block, then place a rubber band or a piece of tape around the bolt to support it. This will aid in the removal of the cylinder head by keeping the bolt out of the way.
Loosen the ten bolts in three one-turn passes in the sequence shown and remove the bolts.
9. Remove the LH cylinder head.
10. Remove the gasket.
