Personally, I don't expect to ever have to do this service. As with many such engines, I expect mine will run for many years without this service procedure ever being performed.
Details can be found in this post in this thread: Valve adjustment info found under hood ...
It will be a labor-intensive process. At least it'll go faster because the 3A92 has only three cylinders haha.
palebeachbum, have you checked your valvetrain yet? Hopefully you can share what you've found.
