Man its nice to know that its a chain and not a belt! There is one thing I'd like to mention though, for the higher mileage guys. I'd still change the chain after about 200k. In my experience on other cars, they stretch. Eventually. It does take a good long time, but I've pulled the timing chain off an old ford that had nearly an inch of slack in it lol. From the factory it was tight.

Now I don't know if Toyota has rectified that situation or not. Maybe they never even had the problem. But I bet they have, on some of their vehicles. It seems to me, that they could fix it by using hardened metals in the chain, but maybe they already do. Somebody else might know. At least check the slack once you get to 200k. It can be the cause of a lot of problems that can be hard to find, but its the timing chain.
