How often do you adjust your valves

When they get noisy. Which is most of the time, lol, those are a pain to get right.
The FSM maintenance schedule says to check valve clearance every 30,000 miles or 36 months.

6,000 miles? That's way too much work, especially if this is a daily driver! You'd be doing valves 4 times a year or more!
30k is plenty enough, the adjusters should not be changing or moving within that timeframe.
Make sure you do it right though, 22RE's are to be done warm. If they're done cold, you will have all sorts of noise from your valvetrain.
And an fyi for others, 3VZE's are done COLD.

I'd go by the FSM recommendation, too.

I like to do it one side at a time. Get the motor nice and hot, then rock out one side, put it back together and warm it back up then do the other. I found that if I tried to do them all at once that by the time I was finishing the motor was cold and those valves would be out of spec.

That's a good idea
Does anyone know the procedure to adjust the valves on a 93 4runner with the 3vze? I just bought this 4runner and it's in desperate need of a valve adjustment however I can't seem to find anything on how to do it. I know the clearances, just don't know the procedure to get the job done. Thanks in advance for your help.

The 3VZE uses shims to adjust the valve clearance, there are lots of threads on how to do this and what tools work best, as well as some tricks and tips on doing this as easy as possible.
Be forewarned though, this is NOT an easy job like a 22RE engine! You cannot simply run a gauge under the valve, adjust the slack and tighten the locknut down! You have to measure clearance, pull the shim, measure shim, then calculate how much larger/smaller a shim is necessary and replace with new sized shim.

Make sure you clean up the half circle in the back of the head real well (and get a valve cover gasket with new plugs if you can) with scotch brite or something they like to leak there and it's kind of a ***** to see and clean back there. Also use some rtv around the new half moon plugs/cleaned up old ones. Even though it's easy you probably don't wanna do vcg a second time and a leak from back there can easily be misdiagnosed as a leaky head gasket or rear main seal

On the 1994 4runner 3.0, does anyone know the intake/exahust value sequence for the driver side? does it go intake, exhaust; intake, exhuast ; intake,exhuast. I am trying to check the clearance of the shims and want to make sure they are within spec
By memory I don't know, take a look at the valve does it line up with the exhaust or intake port?
