Problems:

Oil consumption
The rotary engine in the 1985 Mazda RX-7 is known for high oil consumption due to its design, which requires oil to be injected into the combustion chamber to lubricate the apex seals.
Apex seal wear
The apex seals in the rotary engine are prone to wear and can cause loss of compression, leading to poor performance and starting issues.
Overheating
The rotary engine can generate a lot of heat, and the cooling system must be well-maintained to prevent overheating, which can cause significant engine damage.
Vacuum leaks
Vacuum leaks are common and can cause erratic idling, poor performance, and difficulty starting.
Ignition system issues
The ignition system, including spark plugs and ignition coils, can fail or wear out, leading to misfires and reduced engine performance.
Fuel system problems
Fuel injectors and fuel pumps can become clogged or fail, leading to poor fuel delivery and engine performance issues.
Carbon buildup
The rotary engine can suffer from carbon buildup on the rotor housing and apex seals, leading to reduced performance and efficiency.
Engine mount wear
The engine mounts can wear out over time, causing excessive engine movement and vibrations.
