Maintaining Your Classic Slant 6 Engine Car
If you’re fortunate enough to own a classic car powered by a Slant-Six engine, congratulations! You’re preserving a piece of automotive history. However, owning a vintage vehicle requires a bit more attention and care than a modern car. Here’s some advice to keep your Slant-Six running smoothly for years to come:
Essential Maintenance Tips:
- Regular Oil Changes: This is crucial. Use a high-quality oil formulated for older engines, often with additives to protect against wear. Consult your owner’s manual for the recommended viscosity.
- Cooling System Care: Overheating is a major threat to older engines. Flush and refill your cooling system regularly with the correct type of coolant. Inspect hoses and belts for cracks or wear and replace them as needed. Consider upgrading to an aluminum radiator for improved cooling performance, especially if you live in a hot climate.
- Ignition System Tuning: Keep your ignition system in top condition. Replace spark plugs, points (if applicable), and condenser regularly. A well-tuned ignition system ensures efficient combustion and optimal performance.
- Fuel System Inspection: Ethanol in modern gasoline can be detrimental to older fuel systems. Consider using fuel stabilizers or additives designed to combat the effects of ethanol. Inspect fuel lines for leaks and replace them if necessary. Clean or rebuild your carburetor as needed to maintain proper fuel delivery.
- Brake System Maintenance: Ensure your brakes are in excellent working order. Inspect brake lines, hoses, and wheel cylinders for leaks. Replace brake shoes or pads as needed. Consider upgrading to disc brakes for improved stopping power, especially if you frequently drive in heavy traffic.
Finding Parts and Expertise:
Sourcing parts for classic cars can sometimes be challenging, but the Slant-Six enjoys a relatively strong aftermarket. Here are some resources to consider:
- Online Retailers: Many online retailers specialize in classic car parts, including those for the Slant-Six engine. Do your research and choose reputable suppliers.
- Local Auto Parts Stores: Some local auto parts stores may still carry parts for older vehicles. It’s worth checking with them.
- Classic Car Clubs: Joining a classic car club can provide access to valuable resources, including parts suppliers, technical advice, and a community of enthusiasts.
- Specialty Repair Shops: Seek out repair shops that specialize in classic cars. They have the experience and knowledge to properly diagnose and repair your Slant-Six engine.
Upgrading Your Slant 6 for Modern Driving
While the Slant-Six is a reliable engine, there are several upgrades you can make to improve its performance and driveability in modern traffic:
- Electronic Ignition Conversion: Converting from points to electronic ignition can improve reliability and eliminate the need for frequent tuning.
- Aluminum Cylinder Head: An aluminum cylinder head can improve airflow and reduce weight, resulting in increased horsepower and torque.
- Performance Carburetor: Upgrading to a performance carburetor can improve fuel delivery and increase horsepower.
- Headers and Exhaust System: Installing headers and a performance exhaust system can improve exhaust flow and increase horsepower.
- Overdrive Transmission: Adding an overdrive transmission can improve fuel economy and reduce engine noise at highway speeds.
By following these tips, you can ensure that your classic Slant-Six engine car remains a reliable and enjoyable vehicle for many years to come. Remember to prioritize regular maintenance and seek out expert advice when needed. Enjoy the ride!
