1988 Mazda RX-7 Mileage Danger Zones
The mileage windows when the 1988 Mazda RX-7 most commonly needs attention. Plan ahead, budget accordingly, and inspect before you cross each threshold.

Engine Rebuild Risk Zone
For many RX-7s, 90,000 miles is the point where an engine rebuild becomes a strong possibility due to apex seal failure, coolant seal degradation, or simply carbon locking. This is also when major suspension, electrical, and rust issues…
High Risk / Project Car Zone
