Engine

2.2L Inline-4

• Excessive Oil Consumption
  • Description/Symptoms: Owners report the engine consuming large amounts of oil, often more than 1 quart per 1,000 miles. This can lead to low oil levels, potential engine damage, and fouled spark plugs. Blue smoke may be visible from the exhaust.
  • Solution: Depending on the cause, solutions range from replacing valve stem seals and piston rings to a complete engine rebuild or replacement.
  • Estimated Cost to Fix: $500 - $3000+
  • Recalls: None Found
• Check Engine Light Due to EVAP System Issues
  • Description/Symptoms: The check engine light illuminates, often accompanied by diagnostic trouble codes related to the evaporative emission control system (EVAP). This may be due to leaks in hoses, a faulty purge valve, or a failing gas cap.
  • Solution: Diagnose the specific cause of the EVAP leak using a smoke test or scan tool. Replace faulty components as needed.
  • Estimated Cost to Fix: $100 - $500+
  • Recalls: None Found
• Crankshaft Position Sensor Failure
  • Description/Symptoms: Engine may stall intermittently, experience rough idling, or fail to start. Check engine light will likely illuminate with a code related to the crankshaft position sensor.

Summary:

The 2002 Saturn SL1, while economical, is prone to several issues related to its age. The most concerning are engine oil consumption and transmission problems, both of which can be expensive to repair. Suspension wear and electrical faults are also common.
