The cornerstone of any successful repair, maintenance, or modification plan is the factory service manual. General advice from forums, while helpful, is no substitute for Toyota's official specifications and procedures. The 1G-FE relies on Toyota’s Electronic Fuel Injection
The 1G-FE is an interference engine in its VVT-i variant. A snapped timing belt will cause catastrophic valve-to-piston contact. Replace the belt every 100,000 kilometers (60,000 miles). General advice from forums, while helpful, is no
