Setting the correct ignition timing is critical for optimal engine performance and HEI Distributor Installation is not complete without it.
Using a Timing Light:
- Connect the timing light according to the manufacturer’s instructions.
- Start the engine.
- Shine the timing light on the timing marks on the harmonic balancer or pulley.
- Adjust the distributor until the timing mark aligns with the specified timing degree on your engine’s specifications. Consult your engine’s manual for the factory recommended setting.
5. Testing and Verification
After the HEI distributor installation, thorough testing is essential to ensure proper functionality.
Checking for Proper Operation:
- Start the engine and listen for any unusual noises.
- Check for any leaks around the distributor.
- Check for strong consistent spark at each spark plug wire.
- Test drive the vehicle and pay attention to engine performance. Does it run smoothly or are there any misfires?
6. Troubleshooting Common Issues
During the HEI distributor installation, you might encounter certain issues.
Misfiring:
- Incorrect spark plug wire routing
- Faulty spark plug wires or distributor cap
- Incorrect timing setting
No Spark:
- Faulty HEI distributor unit
- Broken ignition coil wire
- Incorrect connection of wiring
7. Final Checks and Maintenance
After successfully completing the HEI distributor installation, perform these final checks.
Inspect Components:
- Visually inspect all connections.
- Check the tightness of the distributor hold-down clamp.
- Note the condition of the distributor cap and rotor for future reference.
Maintenance:
It’s important to service the HEI Distributor regularly. Consider checking the rotor, cap, and wires annually. The rotor and cap can wear over time and impact ignition performance. Replace them, if necessary.
FAQ
Q1: Is it necessary to replace the rotor and cap when installing a new HEI distributor? While not always strictly necessary, it’s highly recommended to replace the rotor and cap with the new HEI distributor. These parts are relatively inexpensive and they ensure peak performance and prevent future problems.
Q2: What are the benefits of upgrading to an HEI distributor? HEI distributors offer increased spark energy, which leads to improved engine performance, easier starting, and better fuel efficiency.
Q3: My engine is still running rough after the HEI distributor installation. What should I do? Double-check all connections, re-verify your ignition timing, and inspect the spark plug wires for any damage or misrouting. You might consider consulting a professional mechanic if the issues persist.
Q4: Can I install an HEI distributor myself, or should I take it to a mechanic? Many skilled DIYers successfully install HEI distributors. However, if you’re not comfortable with automotive mechanics, it’s best to have a professional perform the installation.
