I'm interested in why you believe the valve adjustment will cure your issue? Most of the motoring public has no idea what a valve adjustment is, and when specific questions like this are posed at our shop, most of the time somebody told the customer somewhere else to perform said service. Is there a check engine lamp on by any chance? How many miles on the vehicle? Anyhow, if I looked it up correctly in my information system, the labor time appears to be 5.2 hours. This particular setup involves replacing shims underneath the cam follower cups, it's a pretty involved process, and not something that is done as a maintenance item very often, which is why I am curious as to how you came to the conclusion of valve adjustment. Hope this information helps, let me know if you need more assistance.

The vehicle has 160,000 miles. I purchased in May of 2007 when it had 70,000 miles. I've done all the maintenence suggested to me for the last 4 years and 90,000 miles. The car has been a little doggy recently. I had a mechanic neighbor listen to the engine idyling and he seemed to think the clicking noise suggested the need for a valve adjustment? Thanks for responding.

Great answer by Prestonfitz. We work on a lot of Toyotas about 5 hours to adjust the valves.Loose valves you may here, tight valves you don't hear until a valve has burned or the engine just starts to have high hydrocarbons when a state smog inspection is done. Toyots hold there valve adjustment well, maybe at 90k you may have to adjust a valve or two, if they were never checked and you plan on keeping the car long term it is a frequently neglected service item on many Toyotas and Honda engines.
