hey guys i need some help from you
yesterday when i was driving home i've noticed a weird clicking sound coming form under my hood when i opened it up i could heard this clicking sound on the right side of the engine bay where the transmission is ( driver side )
Any ideas what it can be it's pretty loud clicking so i getting woried and i do not know what it can be any ideas
Thanks in advance oh my tc is automatic

 

i got the same problem! except the sound is coming from the passenger side

 

mine is coming from the driver side for sure so it's not conected with belt or pulley

 

its a bomb. thats why you dont make enimies. sheesh

 

VVTI

 

what do you mean vvti

 

 

VVTI makes a clicking sound.


the passenger side noise could be a loose pulley.

 

its a vsv on the air box for emissions the canister control valve. it will make a loud constiant click go away them do it again. its normal

 

loose pulley? is that bad -_-

 

lol yeah, go get it checked out

 

i got the same transmission ticking. only at idle (auto), when i depress the gas pedal lightly to accelerate, it goes away. that's in a quiet parking lot with slow accel. driving at speed can't tell. road noise and all. started happening about a month ago. owned it new since 2005. yesterday after a 3 hour drive, as i exited the highway CEL came on. going to shop this week. will update on this next week

 

the thing is that i have injen cai so no air box in my car my cel is on but i have header so no idea if anything else might be wrong
maybe it will sound like a stupid question but were can i check my codes can i do it at auto zone or any other shop

 

there are a few threads about this. I'll summarize it.....

automatic tc
same noise (and no it's not the usual VVTi clicking noise since I compared it to another auto tc) extremely loud from engine bay
comes in especially at idle
went to the dealership 3 times

1. diagnosed intermittent valve sticking...uhm ok they supposedly put a cleaner but the noise stayed there
2. possible injectors issue...again ok fix it?

nope
So I got a S/C instead replaced the injectors so no more noise

 

ok so the clicking sound occurs only when the engine is warm when it's cold right after the start i could hear any clicking
any queses

 

VVTI = Variable Valve Timing w/ Intelligence. That is probably the noise you are hearing.

Is a loose pulley bad? Of course it is. but if you haven't tampered with it, im sure its not lose.


where to get CEL checked. anywhere that has an OBDII Scanner (dealer, auto parts store, etc.). When you scan the car, make sure you write down the number, and look in the book to see what that number means. If you have a header, you are probably going to get a code that is telling you your cat is bad. you should get a anti-fouler and put it in your spipe if you havent already.

 

i have antifouler but in my case it justr doesn't work so i can rid of cel
i should better go to the dealer to check it out but i hate the service since they f..ked my once

 

one anti fouler usually wont do it. get two of them drilled out with a 1/2 inch put em together then there ya go

 

Valve Tick Normal But toyotas have a tendency to have a very loud valvetrain

 

I have this same noise, but it only happens when i release the clutch, I also have a clicking noise at idle, I think it's the hydralic piston that engages when you push the clutch. It needs to be re-lubed maybe?.
