Toyota 2AZ-FE
2.4 L · inline-4 · naturally aspirated · petrol · 2000–2019
Also known as: 2az, 2.4 vvt-i, 2az-fe, az engine, 2.4 four-cylinder, 2az-fxe, 2az-fse
The 2.4-litre member of Toyota's AZ family — aluminium block with cast-iron liners, aluminium DOHC head, VVT-i on the intake camshaft, and the volume petrol engine in Camry, RAV4 and Highlander through the 2000s.
Oil consumption is the pattern fault, traced to piston-ring design on a defined range of production years, and it matters more here than the same phrase does elsewhere: this engine gives little warning. Owners on long service intervals have run them low enough to cause bearing damage without a low-oil light doing anything useful. On any 2AZ of this era, check the level before believing any other diagnosis — a lean code, a misfire and a knock complaint can all be downstream of it.
The second known issue is stripped cylinder-head bolt threads in the aluminium block, which presents as a head-gasket failure that recurs after a conventional repair. A second gasket failure on the same engine is a thread problem until proven otherwise, and needs thread inserts rather than another gasket.

Information, not instruction
CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.
Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

What makes one worth reading:
- The car — make, model, year and engine. The same fault behaves differently on each.
- What you measured, not only what you replaced.
- What actually fixed it — or that nothing did, which is worth knowing too.
