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.

Rotary engines typically consume more oil than conventional piston engines, which can lead to frequent top-offs and potential engine damage if not monitored.

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.

The RX-7's engine relies on various vacuum-operated components that can deteriorate over time, causing running issues and poor performance.

Issues with the fuel injectors can lead to poor fuel delivery, causing the engine to run poorly or not at all.

The rotary engine's ignition system, which includes dual distributors and coils, can be prone to failure, leading to misfires and starting issues.

The exhaust system, particularly on older models, can suffer from rust and corrosion, leading to exhaust leaks and reduced performance.

Gaskets in the rotary engine can wear out over time, leading to leaks of coolant, oil, or air, affecting engine performance and reliability.

The head gasket in the 1984 Mazda B-Series is prone to failure, which can lead to coolant leaks and engine overheating.

The body and frame of the 1984 Mazda B-Series are susceptible to rust, especially in areas with high humidity or where roads are salted in winter.

The carburetor can develop issues over time, leading to poor fuel economy, rough idling, and difficulty starting the engine.

Problems with the electrical system, such as faulty wiring or failing alternators, can lead to various malfunctions including dim lights and battery drainage.

The manual transmission in the 1984 Mazda B-Series can develop issues such as hard shifting or slipping, particularly if not properly maintained.

The brake system, especially the pads and rotors, can wear out quickly and may need frequent replacement.

The suspension components, including shocks and struts, can wear out over time, leading to a rough ride and poor handling.

The Mazda RX-7, particularly the 1984 model, is prone to oil leaks due to its rotary engine design. Seals and gaskets may wear out, leading to leaks.

The rotary engine in the RX-7 has apex seals that are crucial for maintaining compression. Over time, these seals can wear out, leading to reduced engine performance and efficiency.

The rotary engine can suffer from coolant leaks due to worn-out seals or a failing water pump, causing overheating issues.

Problems with the ignition system, such as failing spark plugs or ignition coils, can cause misfires and poor engine performance.

The RX-7's engine might develop vacuum leaks that affect the air-fuel mixture, leading to rough idling or stalling.

Issues with the fuel injectors or fuel pump can cause inconsistent fuel delivery, affecting engine performance.

The rotary engine is susceptible to carbon build-up, which can affect engine efficiency and performance.

The 1984 RX-7 may experience overheating issues due to a failing radiator, water pump, or clogged coolant passages.
