HEY my tacoma makes a chattering noise, not all the time, its mainly when im on the interstate and im going 70mph and i wanta go faster so i give it gas and it will make the noise!!! im not sure if its the gas im using or what. ill take any advise!!! thanks yota ppl

 

theres no way to say without hearing it sadly. it could be anything. i've heard people talk about that thinking their engine is bad, and all it was was a loose intake box. other times exhaust leaks, intake leaks, loose brackets. never know man.

 

so with what i said earlier you dnt think theres anything wrong with the engine its shelf. how would it run or sound if my values are chatting

 

valves can make some ticking. not really a chattering noise that i know of. they would have to be really horrable to make your truck run bad seeing how tacos use lifters instead of rockers. basically there's no adjustments to make like on the older ones. they have caps on the valves that provide the right space. sometimes those can get worn down. and need to be precisely replaced. but like i said. without hearing it i can't really say. sorry dude.

 

what engine to you have? 2.7 four cylinder. or 3.4 6 cylinder? manual, automatic? try shifting down while speeding up, and see if still does it. your engine rpm will be higher, so it may stop, or be more aggressive. could only be while under a heavy load at low rpms, or it could be doing it all the time, which means it may not be inside your engine.
listen for it getting louder, or speeding up, or even stopping while you are shifting down.

 

hey guys i wanta out a lift on my 4x4 tacoma it has independent in the front i was looking to put like a 4" suspension lift from pro comp that comes with the bars that go from the fram to the rear axle im not sure what they are called! i wanted to know whats the easiest way i could go about doing this

 

its the v6, standard, and i dnt every pull anything with it!!! once in a blue moon ill put my 650 mud bike in the back! i would say it only really does it when i put my foot in it, and it will make a noise when im in 1st in the grass trying to spin the tires but thats bc the egine rpms was like at 200 lol thanks for all your advice ill get my friends dad to look at it and show him what all you said and he'll go from there

 

Do you put 87 or 91 octane? If I put 87 or 89 octane on my 1997 4Runner SR5 3.4L every time I get on the gas to pass somebody my engine will knock. What you are hearing is probably engine/piston slap from using low octane gas. That is at least my experience. Good luck!

 

im running the 87 my dad told me to burn all of it out and try the 91 but thats going to be a lot of money to run that in there

 

I'm 100% convinced that running 87 octane is the cause of the engine noise.

 

I have an 86 22re with 256k and I have a slight tick when I'm running around 2k or taking off in first. It's not really persistent but will throw off a few random ones. It's similar to the sound that alot of these engines make when first cranking up. And ideas?

 

I don't think octane would cause chatter. octane would cause a ping (tinny metal sound). a chatter would have something more to do with tranny. When you shift down does the sound disappear?

Does the ticking speed up with the rpms?

 

No, just when I go to take off and only around 1800-2300 rpm

 

Have you checked for anything loose? Plastic, medal, etc.

 

Yea. I can actually go under the hood and pull the throttle and hear it. It sounds like it's coming from the valve cover just above the exhaust

 

Have you checked your spark plugs and wires? A spark tapping can occur if it is arcing. Also I was thinking of a vacuum leak and I have also heard about the timing chain slapping on the 22RE. I can't really tell what it may be without hearing it myself. Is there a way I could tap a fork against a plastic cup or something like that to hear what it sounds like, or maybe a video that sounds like your truck. I know for a fact there are tons of 22RE videos on the internet.

 

The only sound I can explain it to is the sound alot of people have on a could startup but that sound is alot more vigorous compared to a few ticks I have while driving. And wires are new and I have bosch platinum +2 for plugs which u dont have to gap and there about 7500 miles old

 

At this point I have no idea. All I can tell you is to drive it and keep an ear on the sound. If it gets worse quickly then it may be time for a valve adjustment or a timing chain change. Maybe start pulling vacuum lines and see if sound changes when you pull them.

 

Had the noticable sound for about 2 weeks now and it hasent seemed to progress but I really wanna find out what it could be before I start damaging anything heavily

 

Something else I forgot about is your injectors make ticking sounds too. Check out this thread:

Maybe you can find something on here. Sorry I can't help you any further. Good luck
