Known Issues

Ej20 Head Gaskets:

While less prevalent than on later EJ25 engines, early EJ20s can still suffer from coolant leaks due to head gasket failure. Early detection is key.

Avcs Issues:

Active Valve Control System (AVCS) solenoids and oil feed lines can become clogged, leading to rough idling or poor performance. Regular oil changes with quality oil are crucial.

Turbocharger Wear:

Oil starvation or contamination can lead to premature turbocharger failure. Proper warm-up and cool-down procedures are essential.

Clutch Wear:

Due to the performance nature, clutches can wear faster under spirited driving or frequent abuse.

Electrical Gremlins:

Older vehicles may develop minor electrical issues with sensors, switches, or wiring harness degradation.
