When do you adjust the valves on the 3UZ-FE engine?

[Paul Cook]

There is nothing I can find in the Supplemental Maintenance Manual regarding valve adjustment periods other than to "Inspect for excessive Lifter noise and engine vibration. 

I know it has the same "shim" type of valve adjustment as the 1UZ-FE and 2UZ engines and would be an incredible PITA if I ever decided to do one. But I was just curious if anyone has ever bothered to do the procedure for their SC430?

Some engines seem very sensitive to having their valves adjusted. 

The 430 is not one of them.  The subject seems to never come up even in high mileage cars.
