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.

EGR stands for EXHAUST GAS RECIRCULATION.
This is a loop back system between your exhaust manifold and the underside of your filter.
The EGR valve is located between the inlet (exhaust manifold) and the outlet (intake manifold).
About 8-12" below the air filter....toward the passenger side.
EGR carbon built up can be clean.
Check the soft membrane on the EGR valve and see is it crack/torn. If it's in good shape then you may reuse it.
The professional use a vacuum hand tool to determine the travel of the EGR.
There are carbon built up inside the EGR air passage tube too,
Make sure you give both a good cleaning.
The EGR base gasket MUST BE REPLACE!
Order one before you start the job.
Please post more info on the comment window.

hi, i know you say the belts seem good but one way to rule the fan belt or alternater belt out is to pour water onto the belt and if the noise stops then the chances are the belt needs tightening.
If how ever you still have the noise then this would point towards one of the pulleys bearings running dry you can try putting oil into where the bearing is its difficult to get the oil in their as their is very little gap so using a spray oil would be your best option.
If after doing this you still have the noise then your going to have to replace the pulley thats giving you the noise to find out witch pulley it is spray each one in turn with spray lube and see witch one makes the noise less and then this is the one that needs replacing.
Your power steering pump can give you the noise your getting if the fluid is to low so make sure you check all the levels ok.
Let me know how you get on or if you need further assistance ok

Testimonial: "I think the response was right on. Excellent!"
very nice pictoral of where things are located on the corolla .for some reason the PCV valve does not seem to be listed but everything else is ...nice for general maritainence ..
here is what the valve looks like
the valve is probably on the right side of the valve cover .. it has a thick vacuum hose going to the intake manafold .. it plugs into a rubber hole on the valve cover ...
