Car info: 2002 (ap1) 44k miles. Just simple bolt on mods. Hasn't been starved on oil or over-revved since I took ownership 2 years ago. Noise has been there for a few months before stored for winter (chicago). I sandblasted the worm gear from the tct over the winter, didnt seem to have any affect at all on the noise.

Noise is most apparent at idle. Gets more rapid the higher the revs. But also seems to make less noise if not any at higher rpm. But i do have Invidia q300 soooo... its hard to tell ;p also its always there; hot, cold, initial start up.

Let me know what you guys/gals think. All suggestions and help appreciated.

 

Also no CEL.. and runs beautifully. And to explain on how loud it is. I can hear it with top down at idle in a garage and a little bit while sitting at a quiet intersection if i am listening for it.

 

sounds like a pulley, possible tct.

 

Does not sound like TCT at all.

Temporarily run it without the belt on (no longer than 30 seconds) see if the noise disappears.

 

i agree with the guys. my tensioner pulley went bad and made that exact noise, but only as the motor would drop back to idle after a throttle blip.

 

Alright so ran it without belt. Thought i still heard it. But picked up the tensioner pulley anyway bc i did put a stethoscope to it and it sounded shot. Just put on new one. Don't think i hear the noise anymore lol but I've heard it for so long i hear it even in my nightmares il post another vid up

thank you for the quick replies never would have thought pulley.

Still hear it?

 

Sounds the same to me mate, my MY99 has a very similar noise, I also changed the tensioner pulley and have blasted the worm drive from my TCT, not yet ran it with the TCT mod done so will hopefully report back, but am watching this thread with interest, good luck.

Cheers.....Tony..

 

It seems better for some reason haha. But the noise is still there... hopefully we figure this out tozerman.

 

Noise is still there... any other suggestions?
