The Mazda RX-7 from 1983 features a rotary engine (Wankel engine) which is known for having unique problems such as apex seal wear, which can lead to compression loss and reduced engine performance.
Oil consumption
Rotary engines, including the one in the 1983 Mazda RX-7, are known to consume more oil than traditional piston engines. This is partly due to the design and the need for the apex seals to be lubricated.
Cooling system problems
The RX-7's rotary engine can generate a significant amount of heat, which can lead to overheating issues if the cooling system is not properly maintained.
Vacuum leaks
Due to the layout and design of the rotary engine, vacuum leaks can be more common and can lead to poor engine performance and idling issues.
Fuel system issues
The fuel delivery system, including the carburetor setup in earlier models like the 1983 RX-7, can become clogged or require adjustment to maintain optimal performance.
Ignition system problems
The rotary engine relies heavily on a properly functioning ignition system. Faulty spark plugs, ignition coils, and other components can lead to misfires and poor engine performance.

Engine overheating
Rotary engines can be prone to overheating if the cooling system is not properly maintained or if the engine is pushed too hard.
Oil consumption
Rotary engines generally consume more oil than piston engines, requiring frequent checks and top-offs.
Carbon buildup
Carbon deposits can accumulate on the rotor tips and combustion chambers, leading to poor engine performance.
Vacuum leaks
Older RX-7 models can develop vacuum leaks, which can cause rough idling and poor engine performance.
Fuel injector problems
Fuel injectors can become clogged or fail, leading to issues with fuel delivery and engine performance.
Ignition system failure
The ignition system, including spark plugs and ignition coils, can wear out and fail, causing misfires and poor engine performance.
