iirc steff said the master tech at work made a tool instead of the sst, but im not sure what it is.
i had to remove the cams.
there is a vid somewhere of joeo from mr2oc doing it in the car with no special tools, i would check his ste, lovehorsepower.com

I used the lovehorsepower method.
Basically, you use an allen key to compress the valve, and then a flat head screw driver flipped on its side to hold it compressed by the edge of the bucket. Once you have everything in place, use a mini screw driver and a magnetic pickup tool to fish the shim out.

thats what i was thinking, sounds like a 2 person job. luckily the shimms are big. on a 2ZZ if you drop one it could fall in an oil jacket.

It sure would be cool if someone did a detailed how-to with pics for our site and our engines specifically. Mine, like most 3S's, is in need of an adjustment and I've never done it before.

Probably not, unless you've changed something in the valvetrain.
The shims wear very little, even engines with 200K+ don't tend to be out of adjustment.

Adjustment is usually required when you change something with the valves, like valve seats, or a new cam, ect.

This is basically how I did it years ago before I worked for Toyota. Not that hard, but it takes a little bit to get used to it.
Definitely a one man job.
i will do a write up with lots of pictures this weekend. i need to do it soon. this thing sounds like a diesel truck

I am watching this with interest also. I just did a short block in mine and I must have got one or two shims mixed up because I can here one in there tapping away- A write up would be great!
