This is not a task for a beginner mechanic. If you're not comfortable with significant engine work, it's strongly recommended to take your car to a professional mechanic.
The steps outlined below are highly simplified and may not be completely accurate for your specific vehicle. Consult a repair manual specific to your 1997 Camaro Z28 LT1 engine for detailed instructions, diagrams, and torque specifications. Improper torque can lead to serious engine damage.
General Steps (Highly Simplified - Consult Repair Manual):
1. Safety First: Disconnect the negative battery terminal.
2. Access: This is the most challenging part. You'll likely need to:
* Remove the air intake system: This involves disconnecting various hoses and possibly removing the mass airflow sensor (MAF).
* Partially or completely remove the upper intake manifold: This is a significant undertaking requiring the removal of numerous bolts, vacuum lines, and potentially fuel injectors (depending on the specific approach). This often involves removing the throttle body as well. Again, a repair manual is essential.
3. Locate Distributor: Once the intake manifold is sufficiently removed (or partially removed – allowing access to the distributor), you'll locate the distributor.
4. Mark Rotor Position: Before disconnecting anything, carefully mark the position of the rotor relative to the distributor cap and engine. This is crucial for proper reassembly and to avoid misfiring.
5. Disconnect Wires: Carefully disconnect the spark plug wires from the distributor cap. Note the order of the wires so you can reconnect them correctly. A diagram is helpful.
6. Remove Distributor Cap: Carefully remove the distributor cap.
7. Remove Rotor: The rotor usually simply pulls off.
8. Install New Rotor: Install the new rotor.
9. Install New Distributor Cap: Install the new distributor cap, ensuring it's seated correctly.
10. Reconnect Wires: Carefully reconnect the spark plug wires in the same order as they were removed.
11. Reassemble: Reinstall the upper intake manifold and all associated components (air intake, etc.) in reverse order of removal. Pay close attention to all hoses and vacuum lines, ensuring they are properly connected.
12. Reconnect Battery: Reconnect the negative battery terminal.
13. Check for Problems: Start the engine and check for any misfires or other problems.
Important Considerations:
* Repair Manual: A factory service manual or a reputable repair manual specifically for your 1997 Camaro Z28 LT1 is absolutely essential. It will provide detailed diagrams, torque specifications, and step-by-step instructions.
* Tools: You'll need a variety of tools, including sockets, wrenches, screwdrivers, and possibly a torque wrench.
* Parts: Ensure you purchase the correct distributor cap and rotor for your LT1 engine.
This job is far more complex than a simple cap and rotor replacement on older vehicles with easily accessible distributors. Unless you have significant mechanical experience, seek professional help. Improperly reassembling the intake manifold can lead to serious engine damage or failure.
