A New problem just appeared today

Kaiser370z

Hi guys
my Z has 130k miles on it and installed some boltons except headers ( still running oem headers and the headers cats still on too ) and NST pulleys

anyway today I was hanging out with my wife and everything was fine
I decided to give it a full throttle and I did
after I slow down, I stopped in a gas station and I noticed some noise
I tried to listen carefully to know where that sound come from but it's really hard to tell but I think it's not from the head or inside the engine
I felt that it is from a pulley or something like this
it feels like coming from the bottom front section from the engine

I don't know what it is exactly
anyone have any idea ??

BTW the noise sounds like ticking in idle and if I increase the RPM, the ticking gets faster and faster

pop your belt of and check your idlers the vhr has 4 idlers if you count the belt tensioner and at 130,000 (holy **** you have 100k more than me) they could be bad

Flex plate cracked sound?

I don't think so because I am running GTM's flex plate and Torque converter

I got my car checked today
It was the idler's bearings only

Good to hear it wasn't something more serious. I'm curious, how much for this repair?

130K miles.....that's just great. Congratulations. Any other issues during your journey?

I remember that thread it was "OMG why isn't my power steering working...wait no belt"

I kid I kid but yeah the idler bearings are nice to catch while they are loose and not seized, burning the belt or worse. I've seen it (not on a z) where the pulley comes apart and falls into the fan and then you lose a radiator too. Any time the belt is changed its a good idea to check the pulleys for wobble, they should be nice and tight spin freely, no sounds. If you doubt a pulley a mechanics stethoscope on the boss the pulley is mounted to will tell you its bad, a good pulley makes a quit whirr noise a bad one makes either a screechy noise or a grinding/rumbling noise
