Yes, both cars have the 3.3 liter V6. I was planning to replace the valve cover gaskets and spark plug tube seals. I know theres at least some oil leakage. If you start it cold with the a/c on, it makes a lot of belt squeal, despite that belt being fairly new. Last recorded timing belt change was at 56K around 2018, so that’s coming up soon. Looks like spark plug changes are a pain on the rear three cylinders, so I might as well replace the gaskets, etc. I’m more on the fence about replacing the thermostat and water pump. I used to be in the school of “replace it while you’re in there,” but now I’m questioning that since a lot of aftermarket parts are garbage. I know the water pump was replaced with the timing belt, but now I’ll have to check my records to see if it was done with actual Toyota parts.
