Inside 2GR-FE Engine Variable Valve Timing VVT Camshaft Gears - Intake Exhaust Camry Highlander RAV4

The Toyota 2GR-FE 3.5-liter V6 engine Variable Valve Timing VVT camshaft gears are rarely seen on video. A few videos feature the exhaust cam gear which is relatively easy to disassemble. The intake gear is not easy to disassemble so nobody goes to the trouble. This video includes rarely seen footage of the inside workings of both gears, exhaust and intake. We examine the oil flow passages, the advance and return mechanism, the lock pin, the stops for retard on the exhaust side and advance on the intake side, and other specific features of each gear. 00:00 Intro 0:26 Disassemble the camshafts 1:01 Assembly bolts 1:55 Exhaust gear 3:23 Exhaust return spring 4:00 Exhaust gear failures 4:50 Exhaust advance limiter 5:15 Exhaust oil passages 5:59 Exhaust locking pin 6:33 Intake gear 7:00 Balancing rotor 8:10 Mechanical advance stop limiter 8:29 Locking pin 9:20 Lubrication sliders and leaf springs 10:45 Intake vs. Exhaust return action 12:15 Re-assembly out-take
