Toyota Interference engines list
Complete Toyota Interference engines list
Most late model Toyotas have interference engines, meaning the valves and pistons will collide if the timing chain fails. This leads to extensive engine damage. The Toyota interference engines list is below, but examples include the 2AZ-FE 4-cylinder, the 3MZ-FE V6, the legendary 2JZ-GTE, the modern 2GR-FKS V6, and the Lexus 4.6L 1UR-FSE V8.
Toyota started using timing chains instead of belts in the early 2000s. Chains are more durable than belts, but still wear over time and may need to be replaced. Toyota require vigilant oil changes and scheduled maintenance to prevent premature timing chain failure and extremely expensive damage. Follow intervals recommended by Toyota.
