1986 Mazda Rx2 problems

Common 1986 Mazda Rx2 problems

The Mazda RX2, produced in 1986, is known for several common problems that owners have reported over the years. One of the most significant issues is related to the apex seals in the rotary engine. Apex seals are crucial components in a rotary engine, as they seal the combustion chamber and prevent leakage of gases. Over time, these seals can wear out or become damaged, leading to reduced engine performance, increased oil consumption, and even engine failure. Mazda replaced many engines in the RX2 due to these issues, and it wasn't until the release of the RX7 that they managed to significantly improve the reliability of their rotary engines.

Another common problem with the Mazda RX2 is the finickiness of the carburetors and spark plugs. The rotary engines in the RX2 were known for being sensitive to the condition of the carburetor and spark plugs. If the carburetor was not perfectly tuned or if the spark plugs were not in excellent condition, the car would run poorly. This issue was particularly pronounced in the carbureted models, as they did not have the benefit of fuel injection, which can provide more precise fuel-air mixtures and better overall engine performance.

The rotary engines in the RX2 also required frequent oil changes and topping up, as well as regular replacement of spark plugs and point sets. This was a time-consuming and sometimes expensive process, as it required more frequent maintenance than many other cars of the era. In addition, the early rotaries were known to eat through spark plugs and point sets, which could further contribute to poor engine performance and reliability issues.

Another issue that some RX2 owners have reported is related to the ignition system, specifically the ignitor module and coils. If the ignitor module is failing or if there is a problem with the power feed to the coils, the engine may experience issues with idling and overall performance. In some cases, a faulty coil may also be the culprit. These issues can be challenging to diagnose and repair, as they require a thorough understanding of the ignition system and its various components.

Finally, some RX2 owners have reported issues with seized rotary engines. This can occur if the engine has been sitting for an extended period or if there has been some engine damage in the past. In some cases, the engine may be salvageable, but in others, a new motor may be necessary. If the engine is able to rotate, it is possible to repair or rebuild it, but if it is completely seized, replacement may be the only option.

In summary, the Mazda RX2 is known for several common problems, including issues with apex seals, carburetors, spark plugs, ignition components, and seized engines. These issues can be challenging to diagnose and repair, but with the right knowledge and tools, it is possible to keep an RX2 running smoothly and reliably. Regular maintenance and attention to detail are key to ensuring the longevity and performance of these unique and fascinating cars.

This means that if you want to own one, you have a couple of options. One is to find a used RX-7 in the United States that is a 1995 year model or older.

Are Mazda RX-7 easy to work on?

Leaving aside those you see at the race tracks, where they get tremendous horsepower out of a 1.3 liter engine, they are really rather simple machines compared to piston engine cars. They take 1/2 the time to rebuild, and it's really very hard to mess one up if you any mechanical knowledge whatsoever.

Why was the Mazda RX-7 discontinued?

Unfortunately, the RX-7 was discontinued in most of Europe by 1996 due to emissions regulations, although Mazda continued to produce cars for some markets, eventually boosting power output on later Japan-only models to as high as 280PS. The year 2002 marked the end of one of the most exceptional sports cars in history.

What is the problem with the rx7 FC?

Engine Issues: One of the most common problems with the RX-7 (FC) is engine issues. This can include problems with the rotary engine, such as seal failure or low compression, as well as other mechanical issues like overheating, coolant leaks, and electrical problems.
