Problems:

Overheating
The 1985 Mazda RX-7 with the N3 engine is prone to overheating due to the rotary engine design which generates a lot of heat.
Apex seal wear
The rotary engine's apex seals can wear out prematurely, leading to compression loss and reduced engine performance.
Oil consumption
The rotary engines in the RX-7 are known for higher than average oil consumption, as oil is used to lubricate the apex seals.
Vacuum leaks
Vacuum leaks are common in older vehicles and can lead to rough idling and poor engine performance.
Ignition issues
The ignition system, including spark plugs and ignition coils, can fail, causing misfires and poor engine performance.
Fuel system problems
Issues such as clogged fuel injectors or a failing fuel pump can lead to poor fuel delivery and engine performance.
MAZDA RX-7 1984

The 1984 Mazda RX-7 is a classic coupe featuring a 1.3L engine with a power range of 122 to 148 hp. Manufactured by Mazda Motor Corporation in Hiroshima, Japan, this gasoline-powered vehicle is designed for optimal performance and style with its sleek two-door body.

Problems:

Rotor apex seal wear
The rotary engine in the 1984 Mazda RX-7 is prone to wear on the rotor apex seals, leading to loss of compression and engine performance.
Oil consumption
Rotary engines typically consume more oil than conventional piston engines, which can lead to frequent top-offs and potential engine damage if not monitored.
Cooling system issues
The rotary engine can generate a lot of heat, making the cooling system critical. Problems with the cooling system can lead to overheating and engine damage.
Vacuum leaks
The RX-7's engine relies on various vacuum-operated components that can deteriorate over time, causing running issues and poor performance.
Fuel injection problems
Issues with the fuel injectors can lead to poor fuel delivery, causing the engine to run poorly or not at all.
Ignition system failures
The rotary engine's ignition system, which includes dual distributors and coils, can be prone to failure, leading to misfires and starting issues.
Exhaust system corrosion
The exhaust system, particularly on older models, can suffer from rust and corrosion, leading to exhaust leaks and reduced performance.
Gasket failures
Gaskets in the rotary engine can wear out over time, leading to leaks of coolant, oil, or air, affecting engine performance and reliability.
