Shims are ONLY available from the Toyota dealer. The special tools are reasonably priced and can be found on EBay or elsewhere on the Internet. That said, I'm a professional mechanic. Even for me, the job is a PITA [difficult] This is not a job for an amatuar mechanic. It will be an expensive job.

SOURCE: need to know how to adjust valves, or a print-out

This engine utilizes shims to set proper clearances, you will need a micrometer, valve clearance adjustment tool set for shimmed lifters,small magnetic arm, appropriate shim selecting charts (manufacturer will have this if you can get the nec. measurements).
Measure thickness of shims removed (using micrometer) and use this formula where T=Thickness of old shim; A=Valve clearance measured; N=Thickness of new shim required.
Intake valves:   N = T + (A - 0.02 mm (0.008 in.)) Exh. valves:     N = T + (A - 0.25 mm (0.010 in.))
Then you need to find shims as close as possible to the calculated values.
Valve clearances (cold) are as follows: Intake 0.15 - 0.25 mm (0.006 - 0.010 in.) Exhaust 0.20 - 0.30 mm (0.008 - 0.012 in.)
Note, if you are not familiar with precision measuring using a micrometer, this may be better left to a trained tech. These are high revving little power plants and you don't want a problem at 8K rpm.

You might as well inspect/replace the PCV valve while you're there.

How do you adjust the valves


you need to state which engine you have. Sometime in the 90's a lot of Toyota motors went to a shim system for valve adjustment so the usual simple valve adjustment techniques are not used. Job for a dealer or toyota specialist shop. You need to have a good reason to adjust them anyway. What is the compression in each cylinder./Are the valves burned?

Can the valves be adjusted on a 1996 Toyota Camry 2200 (number on the valve cover)


Yes they can but you will need a couple of special tools. This style of valve adjustment is Called a shim an bucket. First the valve to cam clearance needs to be measured. Then if that measurement is out of spec you will need to use. Couple of special tools to compress the valve so that the shim can be removed. Once the shim is out you will need to measure it's thickness with a micrometer than figure out the correct size replacement. The replacement will need to be purchased from the dealer. These are not easy or DIY friendly. I can give you more info if you think you want to tackle it.

How to adjust the valves on a 1993 toyota camry 2.2


It is not an easy process. It has cam buckets with shims under the cam lobes. You need to adjust them with different thickness shims. you need to measure the clearances then change the shims to adjust them. This may be able to be done with a special tool to hold down the valve otherwise the cam shafts need to be removed. I would reccomend checking the clearances whilst the valve bucket is at the back of the cam and if the clearance is close to that reccomended it will be ok. If they are out a long way have a Toyota specialist adjust them. Often they will not need adjusting for the life of the engine.

Is valve adjustments needed on 2000 camry V6 I am hearing noises that seems like coming from under valve cover, you can hear the noise from inside car,but not from outside of car. I was told this engine...


The valve adjustment usually isnt done unless there is valve noise. If you think its valve noise, have the dealer check it or a shop that does a LOT of Toyota work. Special tools and shims are needed to adjust the valves. Its a LOT of work and will not be cheap. You will want to replace the spark plugs at the same time.

Are the valves adjustable on the 1990 3.0L? I


1) The valves are adjustable, but they are of the shim-type adjustment. You will need to obtain the proper shims from a dealership parts department.

2) Any Toyota dealer can, by you giving them your VIN, tell you whatever was done to the vehicle under warranty

3) There are no special service campaigns for bed replacements, nor has there ever been one. Any bed that 'was' replaced was under factory "goodwill", to maintain customer satisfaction.

I have a 4runner 1994 v6 3.0....how do I turn down the idel


You need to adjust the timing on the belts. This can be adjusted with a wrench. Adjustments should be made with slight measurements, a hair can change it. After adjustment, turn the car off and restart. Drive for a block and see where the RPM goes to when at idol. Keep adjusting until you get around 700-1,000 RPM.
Let me know if this helps.

Hi, I have a 1994 4runner and I want to turn the idel down , how would I do this thanks so much. v6 3.0


here is the same disappointing news i got.. with the 3.0 you can adjust the idle .. which is good and bad! good being it will adjust itself,, bad being if its idling a lil high you cant turn it down some...most common reason it will idle high is due to a bad sensor or a vac, line leak.

however.....
in my case mine was idling about 1200 to 1500 rpms and huge power loss,,, i just dropped heads off today at cylinder head shop with burnt valve lol
