I checked the valve clearance. With 220k mi the clearance was:
exhaust; valves for 1,2,3,4 is .011" 5,6 is .012" range is .010-.014
intake; 1 is .006 2,3,4,5,6 is .007 range is .006-.010
With the 1fz motor, it uses shims to adjust. As the motor wears, the clearance between the valve lifter and camshaft should increase, right?
