Known Issues for This Vehicle
Rotor housing wear
The RX-7's rotary engine can suffer from wear and scoring of the rotor housing, leading to compression loss and reduced power.
Apex seal failure
The apex seals in the rotary engine are prone to wear and breakage, which can result in poor engine performance and starting issues.
Coolant seal leaks
Coolant seals may degrade over time, causing coolant to leak into the combustion chamber or oil system, potentially leading to overheating or engine damage.
Oil consumption
Rotary engines tend to consume more oil than piston engines, which can lead to frequent oil changes and monitoring.
Vacuum leaks
Vacuum hoses and connections can become brittle and leak over time, causing inconsistent engine performance and idle issues.
Ignition system problems
The ignition system, including spark plugs and ignition coils, may require frequent maintenance due to the high-revving nature of the rotary engine.
Fuel injector issues
Dirty or failing fuel injectors can cause poor fuel delivery, leading to rough idling, misfires, and decreased fuel efficiency.
Exhaust emissions
Rotary engines may produce higher emissions, which could lead to difficulty passing emissions tests and potential legal issues.
Heat management
The RX-7's rotary engine can produce a lot of heat, necessitating a well-maintained cooling system to prevent overheating and maintain performance.
Fuel economy
The rotary engine's design often results in lower fuel efficiency compared to conventional piston engines, leading to higher running costs.
