Mazda RX-3 / 808/ 818 (1971-78)

COMMON FAULTS
Please Note: Common Faults in Regularly Used Vehicles vs. Low-Mileage Stored Vehicles that have been used consistently over many years, accumulating approximately 10,000–12,000 miles annually, are more prone to common faults due to regular wear and tear. These issues typically arise from the natural aging of components subjected to frequent use, such as engine parts, suspension systems, brakes, and tires. In contrast, vehicles with low mileage that have been stored or preserved are likely to experience different types of issues. These vehicles are often better maintained to ensure their longevity and may avoid some of the typical wear-and-tear problems seen in regularly driven cars. However, they can still face unique challenges such as degradation of rubber seals, corrosion from prolonged inactivity, or fuel system issues caused by old or stagnant fuel.

The Mazda RX-3, a classic car from the 1970s, is known for its unique rotary engine. However, like any vehicle, it has its share of common faults:
1. Engine Issues: The rotary engine, while innovative, can suffer from apex seal wear, leading to loss of compression and power. This is a common issue with older rotary engines.
2. Cooling System Problems: The RX-3’s cooling system can be prone to overheating, especially if not maintained properly.
3. Oil Consumption: Rotary engines are known for higher oil consumption compared to piston engines. Regular oil checks and top-ups are essential.
4. Electrical Issues: Older models may experience electrical problems, such as faulty wiring or issues with the alternator.
5. Rust: Like many cars from the 1970s, the RX-3 can be prone to rust, particularly in the wheel arches, sills, and underbody.
Despite these issues, the RX-3 remains a beloved classic for many car enthusiasts.
