i recently put on my cai been driving it for almost a month and now im hearing like a clicking sound i opened my hood and seems like i hear it on the left of my engine. Has anybody have that same problem.

 

check the brackets and such also check where the extended portion of the intake goes through the body it usually rubs on the body but you won't be able to see it to tell i put some foam there you may want to consider the doctor isotopes intake fender mount...i may have one for sale btw i gotta check

 

by left side do you mean passenger side or driver side

 

passenger side man... i dont think its in the fender from the intake

 

you know what,i know what your talking about! i recently got on 08 scion as well and once i installed the CAI i started hearing clicking noises by the engine.

I actually went to the dealer and told them about it but they said its fine!It sounded normal according to them, but they were probaby being lazy!I sure wouldnt mind knowing the answer to that problem though!

 

well i dont know about it being normal why would it be normal if when i got the car it wasn't making that noise. once i put my cai it started doing that like a month later. but is that clicking sound on the passenger or driver side in your car?

 

the clicking sound is normal. the CAI just amplifies it even more than usual.

 

alright thanks man i really appreciate it i thought i messed up my car already..... not to challenge your answer to my question but where did you get this info.?

 

Search around and you'll see that your question will be answered by something along the lines of mine. Lots of people have asked the same thing as you.

 

ok well its kool i believe you well at least i want to... lol don't want something wrong with my car just got it in nov.

 

Are engines do make A LOT of ambient noise that is muffled by the stock air box

 

yea but i dont have have the air box i have the cai jose06tc said that its just the sound that is apmlified by the cai

 

yeah i was agreeing with him

 

mine does it when iturn it off.

 

back to my post...i meant the drivers side and some of it is from the engine making noise just b/c but also sometimes it is from the cai and you avoid some of it but sometimes you can't get rid of all of it

 

I know what u mean i get it too where the belts are or it sounds like the valves are tappinig! it goes away after a while but its there and makes me worry...also does ur 08 TC idle funny when u shift to neutral on the freeway mine revs itself after dropping to 700 and comes back up to stay at 1.5K when im under 30 MPH the idle drops back down

 

well i have a manual what do you mean 700 do you mean 7k?when im doing 3 on 4th gear its around that rpm.

 

well what id does on the frway if i shift to neutral the rpms drop like normal to 700 RPM, then after it hits that point it bounces back up to around 1.5 and stays there for a while or if i slow down to less than 25 mph it will idle normal, its like i have an auto tranny ecu, u kno when u let off the gas on an auto it revs somewhere around 1.5K RPM i im wondering if other manuals do this, and it did this with the stock intake also

 

If this is what I think it is, it's the vacuum switching valve (the thing connected to the green thing in the picture below):



I used to have the DME front strut bar installed, and the VSV was pressing against the bar after installation. All the rest of my powertrain stuff is stock, but I heard a ticking noise whenever idling, and a sharp ticking noise when starting. I'm pretty sure it was this thing's ticking being amplified through to the body.

On most of the CAIs I've seen, you have to mount the VSV on the tube of the CAI, which may conduct vibrations to the rest of the body. I'm curious if it's this thing's ticking that you're hearing.

 

I have had the TRD intake on my tC for a month or so now and I haven't heard anything.
