If you have time, please upload pics when you install.Something really cool finally showed up out of Australia. On the Toyota #1FZ blocks we get to enjoy a timing chain instead of a silly belt. The timing chain has a timing chain guide and adjuster. The adjuster, located just above the thermostat, is hydraulic and uses oil pressure to keep slack off the timing chain. Low oil pressure, wear, etc keeps the adjuster loose and it’s what makes your timing chain noisy. There are lots of noisy timing chains out there.
This bad boy is self-adjusting. It has a firm spring pushing the adjuster forward all the time. But it goes one step further, it has a ratcheting anti-reversing lock built into it. As the timing guides where AND the adjuster adjusts, it will click and prevent the adjuster from going slack. Really smart setup. Although neither of my LX450s needs it currently, I will be trying it out on the turbo truck. Excited to see how it turns out.
