For a "shim under bucket" adjustment, clearances are measured, written down and compared with specification. Camshafts must then be removed, and the correct shims installed to arrive at the correct clearances, re install cams, and recheck clearances. $1000.00 is in the ballpark for this job. What I am trying to find out is on this model, do they really have to do all of that. As I stated, two toyota mechanics have said that they ONLY tear down and adjust if noise is present. The real question is do these valves get noisy when they need adjustment, or not?
