  1. Been chasing a rattle from an ES300 with your favorite engine the 1MZ-FE for a while now in the fleet. It's in it's mid 20's so for a car, it's tough to get them to fix anything on it. Could be different. I don't believe it's the i- version. but they subscribe to time is money so they are slow to respond. Glad to hear Toyo guides are not easily broke. That was a suspect for a while. As was the timing tensioner. Seen a video lately that said not enough oil was getting to the gear so do a valve cover replacement with the small o rings inside the cover. One is a figure 8 double o ring. The engine seizing and grenading is scary to think about. Lukily they are using it for very low miles and local in town no freeway driving. It's peculiar. Many symptoms that fit other circumstances. Startup rattle for 5-8 seconds as you said. But also rattle from 1800-2300 rpm and none in the rest of the power range. They greatly fear the parts cannon. Hard to say, because I want to save the car but also not scare them. .
