You sure the noise isnt from something else? 40K is way to early to be needing a valve adjustment. You might want to get it checked out first to try and pinpoint the noise.

The valves aren't adjustable.

Rather than getting something that isn't needed you should probably find out where the noise is coming from.

the 2AZ makes a tick noise. Thats just one of the characteristics that we I4 drivers learn to live with. is this the noise? http://youtube.com/watch?v=VU8OyMq78tg

The sticker on my hood underside in my 2005 2AZ has the valve clearances on it and that this is the only tune up adjustment. Why would they list a clearance if there was no adjustment. Does not make sense.

the 2az-fe just generally makes a ticking noise....thats how the valvetrain of the engine sounds and you get used to it (i love the sound of my 2az).....post a clip of the noise, but id hazard a guess its just the normal sound of a healthy 2az

The 2AZ-FE engine uses a "shimless" valve lifter design, meaning it cannot be adjusted. However, the valve to lifter clearance CAN be adjusted by swapping out a lifter that is the correct size. According to the service manual, the lifter is available in 35 different sizes.

edit: www.camrymanuals.com, the 2AZ-FE file, it talks about this. (page12)

HaHa, I had to TRD:


2004 Toyota Camry L4-2.4L (2AZ-FE)

Vehicle Level Engine, Cooling and Exhaust Engine Valve Clearance Adjustments AdjustmentsVALVE CLEARANCE
ADJUSTMENT
  1. REMOVE FRONT WHEEL RH
  2. REMOVE FRONT FENDER APRON SEAL RH
  3. REMOVE ENGINE COVER SUB-ASSY NO.1
  4. REMOVE SPARK PLUG
  5. DISCONNECT VENTILATION HOSE
  6. DISCONNECT VENTILATION HOSE NO.2
  7. DISCONNECT ENGINE WIRE
  8. REMOVE CYLINDER HEAD COVER SUB-ASSY



a)Remove the bolt and disconnect the engine wire harness clamp.b)Remove the 8 bolts, 2 nuts, cylinder head cover and gasket.
  1. SET NO. 1 CYLINDER TO TDC/COMPRESSION



a)Turn the crankshaft pulley, and align its groove with timing mark 0 of the timing chain cover.b)Check that the timing marks of the camshaft timing gear and sprocket are aligned with the timing marks of bearing caps No. 1 and No. 2, as shown in the illustration.
  1. INSPECT VALVE CLEARANCE HINT: Inspect and adjust the valve clearance when the engine is cold.



a)Check only the valves indicated on the left.1)Using a feeler gauge, measure the clearance between each valve lifter and camshaft.2)Record valve clearance measurements that are out of the specified range. These measurements will be used later to determine the size of the adjustment shim to be installed.


b)Turn the crankshaft clockwise 1 revolution (360°) and set the No. 4 cylinder to TDC/compression.


c)Check only the valves indicated on the left.1)Using a feeler gauge, measure the clearance between each valve lifter and camshaft.2)Record valve clearance measurements that are out of the specified range. These measurements will be used later to determine the size of the adjustment shim to be installed.

Valve clearance (Cold)

  1. ADJUST VALVE CLEARANCE NOTICE: Be sure not to turn the crankshaft without the chain tensioner.



a)Turn the crankshaft clockwise 1 revolution (360°) and set the No. 1 cylinder to the TDC/compression.b)Place paint marks on the timing chain and camshaft timing gear/sprocket.


c)Remove the 2 bolts and chain tensioner.


d)Remove the No. 2 camshaft.1)Fix the camshaft with a wrench and then loosen the sprocket bolt. NOTICE: Be careful not to damage the valve lifter.




2)Uniformly loosen and remove the No. 2 camshaft's 10 bearing cap bolts in the sequence shown in the illustration. Then remove the 5 bearing caps.


3)Raise the No. 2 camshaft and remove it. Then remove the sprocket bolt.4)Remove the camshaft timing sprocket and the timing chain from the No. 2 camshaft.5)Remove the camshaft timing sprocket from the timing chain.


e)Remove the camshaft.1)Uniformly loosen and remove the camshaft's 10 bearing cap bolts in the sequence shown in the illustration. Then remove the 5 bearing caps.2)Remove the camshaft.


f)Tie the timing chain with a string. NOTICE: Be careful not to drop anything inside the timing chain cover.


g)Remove the valve lifters.


h)Adjust the valve clearance.1)Using a micrometer, measure the thickness of the removed lifter.


2)Calculate the thickness of a new lifter so that the valve clearance comes within the specified value.


Valve clearance


3)Select a new lifter with a thickness as close as possible to the calculated values.

From a maintenance standpoint, they aren't adjustable.

If you replace any of the valvetrain componants you will need to measure the clearance and install the correct lifter/shim if it's out of specification. There isn't any adjustment involved...

The shims do wear, as do the Cam lobes. It is good Preventative maintenance to check/adjust clearance at the least every 60-70k.

Per Toyota Maintenance intreval, Check you maintenance guide that came with your car, it should state the valve clearance check/adjustment in there.

Dont worry about light valve ticking, i have owned seven 4 cylinder cars and trucks and every single one has made this sound. It never affected the longevity of the engines in any way. As long as the valve clearance is within specs, it wont hurt anything. In fact, the valve to worry about is one you DONT hear as maybe it is too tight. I know the sound is a little unnerving to some but if you realize it is normal you will stop hearing it.

I think i'd let it tick, if the sound got too loud i might pull the cam cover and check the clearance myself. To do all the work shown in the post above, you might as well pull the head and do a valve job while you are at it if you are doing all that, thats what i would do.

Besides which, some mechanics dont know how to measure valve clearance, one time i took another car to a shop to have the valves adjusted, and when i got it back from them it wasnt running right. So i checked the clearances myself and EVERY SINGLE valve was adjusted too tight, some had NO clearance at all and would have burned in a few hundred miles. That is the last time i ever let somebody else adjust my valves.

Dont worry about the ticking, if it bothers you too much, check the valve clearance yourself. And if any are out of spec, then decide what to do. (Probably dont need to do anything to the valves and the car will run like a champ for 200,000 miles.)
