Toyota 1GR-FE 4.0 V6 Engine Guide: Specs, Problems & Reliability

The 1GR-FE is Toyota's 4.0L (3,956cc) aluminum V6 with a timing chain. It powered the 2003–2024 4Runner, 2005–2015 Tacoma, 2007–2014 FJ Cruiser and 2005–2009 Tundra V6. Early engines are single VVT-i (236–245 hp); the 2010+ 4Runner and FJ got dual VVT-i with roller rockers (258–270 hp). It is one of Toyota's most durable V6s, with 250,000+ miles common. The real known issues are an early front timing cover oil leak, occasional head gasket seepage at high mileage, and secondary air injection pump failures on later trucks.
