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 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 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 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

 

i beat you to it.. look up before your post. lol

 

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)

 

^^i knew that link was useful....thats why i submitted it as a sticky

 

haha i didnt even notice camralon....i guess i kinda post without reading the other posts sometime
but yeah all the 4 cyl guys know how the engine sounds....and how theres no issue with it

 

lol. yea

 

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.)

 

I brought it to the dealership and they fix the ticking sound. It was the bearings that were loose and the replace the engine shortblock for free because it was still on warranty.

 

Horray for Beer!:woot:

I mean Warranty.....
