The 3.0/3.4 V-6 and 2.4/2.7 4 cylinder engines seem to love to loose torque on the Valve cover bolts. Luckily I haven't had an issue with this on my 22RE. Thermostat was done about 65k ago with a factory Toyota one, seems healthy according to my AutoMeter gauges, runs bang on the advertised 182 degrees.
Kicking off the road trip tomorrow as soon as I can sneak out of work and come home to pick up my guns, the military frown on me bringing them to work even though I fly with one, go figure...
Will post updates here, tools and spare things mentioned in this thread are all loaded, truck got suspension and drivetrain greased fresh this evening.
Starting mileage should be in the 318,225 ballpark. Will likely be knocking on the door of 322,000 by the time I get home. I'm excited to get it out on the road and stretch its legs.
