Sounds sort of like a valvetrain cardiologist.

Wonder if the techs had a special class on this (being facetious). I think its an easy-out remedy Toyota came up with because of all the blowback they're probably getting over the cost of getting adjustments done on older vehicles.

Our 03 6cyl 4Runner has 96k miles. The maint. schedule calls for checking valve clearances at some point (I don't remember offhand when, but I think its about right now). When I talked to the SM about it, he said it would take 23 hours to do, and it was complex. I've decided to completely skip this, unless something happens engine-wise, and then it could be too late.

Toyota: try hydraulic self-adjusters. Yes we'll all happily pay an extra $xx for the vehicle up front for the additional cost of the system.

I notice the 3.5 in the Avalon has hydraulic adjusters, and maybe in the other models that use this engine as well?? Hard to easily find this info.
