theres a monster in my z

[Eclipsewhipping]

ok well i just noticed there is a weird noise comming from the driver side of my car. it only makes the noise when the car is idiling tho.. it is like a weird growling noise like , rIn RoN RiN RoN. well thats the best description i could give. also you cant really here it if u pop the hood, but you can here it clear as day if u put your ear against the driver side fender, any idea what this could be, my friend said it sounded like a bad distributer bearing or something but as i just found out there is no distributor. im hoping its not my turbo. but i dont think it is cause when i rev the car it goes away and comes back when its idling or driving at low rpms

any help would be greatly apreciated.

hmmm that's wierd, IDK man, I mean it could be a relay of some kind? and isn't the ECU right around there too... maybe it has something to do with that, sorry I can't help ya.

[Eclipsewhipping]

i think the ecu is on the passenger side but im not sure, maybe

[xXxRocker5150]

Yea it is, my fault, I misread your post.. hmmm that's tricky...

[k3smostwanted]

that would be you're AIV's gurgling...

rip em out...they are about useless anyways, and its cheaper to remove them than to have the unit rebuilt.

OK well im stupid ,,haha what is the AIV'S and what are they supposed to be ment for and why are they garguling .

they are gurgling because the valves are not working any more.

Air Induction Valve's...takes air from your Cat's and recirculate its back into the intake tubes.

sometimes you can drill a small hole in the bottom of one of the hoses and this will stop the gurgling. most people remove them...

here is a pretty good write-up on cleaning them...

if you have stock Mid-pipes then you will need to seal the metal line coming off of the Cat's once removed or you can just buy testpipes

nothing really to worry about except that stupid gurgling sound. you can lose a good 30lbs in weight by removing them also...

[Eclipsewhipping]

haha ya, 30 pounds is a lot in my opinion, and that garguling sound is kinda creepy..

[probehtr300]

yeah either AIV's, or the carrier bearing which might have been what your friend was refering too., its the support bearing in the middle of the 2-piece drive shaft. When that bearing goes bad it can make a sound like that

[stephenp]

i dont think his driveshaft is going to be spinning while hes sitting still..... or hes the monster and runs next to his car and pouts his ear against his fender while driving
better yet pops his hood while driving

oh my god its houdini


sorry i couldnt be of any help

nope...gurgling is AIV's, mine and almost every other Z32 out there make the same sound. plus, guess where the AIVs are located...inside the fender wells, so it would make sense that it would be loudest when he puts his ear next to the fender.

its really a simple processs to take them out...

1. remove wheel
2. remove fender well plastic covers
3. unbolt AIVs
4 plugs all holes that the hoses from the AIVs are leading to.

you will be surprise at how heavy they are...some people get them rebuilt, i dont know why. most people just remove them completely because they are useless....

[edtotalfitness]

this is interesting, a 30lb reduction for very light labor. Hmm... should this be recommended for those who have working ones? I mean why not if they don't serve much purpose, right?

yeah, aiv's are prettymuch useless... just help at low rpm's for something.... no harm in pulling them out as long as you plug all the holes that they came from..
