Engine Swap – Quick reference donor list (North America)
The 2AZ-FE 2.4L inline-4 was one of Toyota’s most widely used engines in the 2000s and early 2010s, meaning Scion tC owners actually have a surprisingly large pool of donor vehicles when looking for a replacement engine.
Why some 2AZ-FE engines burn oil
The oil consumption problem came from piston ring design, specifically:
- Low-tension oil control rings
- Insufficient oil drain holes in pistons
- Carbon buildup causing rings to stick
This affected many Toyota vehicles roughly 2006–2011, regardless of whether the engine came from Japan or North America. If you’re shopping for a replacement engine, keep in mind it could still have oil consumption issues if it falls within these years.
