hey guys i have my c32 that has a code 3 intake/pulley and k&ns and other small mods...anyways recently i noticed a bearing sound or knocking noise coming from under the hood. The noise goes away a bit when the engine gets warm(to operating temperature since im in toronto, Canada and its pretty cold now). However the noise is amplified when the car is put in gear ( D or R ). i took off the serpentine belt today and moved the pulleys and all bearing seemed fine, i couldnt hear anything either with my stethoscope. The tensioner pulley was moving a bit though and it kind of seemed consistent with the sound...anyways i dont know what it is and my local shop doesnt either...im not really intrested to take it to the stealership cause theyre gunna charge me an arm and a leg plus give me **** for my code 3 pulley. So if anyone has tips comments or any help please respond cause i dont know what im gunn do

** I just called HP in California and they did confirm that the OEM bearing is the same for the Code 3 bearing.......................
If that's the case, I believe there's a post on here where someone is selling for $25.00??

tensioner is spring loaded and will move as the belt runs over it. with the engine running VERY CAREFULLEY use the stethoscope on the end of the bolt attaching the various idler and s/c pulleys . the one thats bad will be obvious

i tried that with a pry bar listening to the end of it but got nothing. however i took it to the shop that installed my code 3 pulley and they said it all seems good but that was ebcause my engine was very warm. its a lot worse when the engines cold or in gear. anyways ill get a stethoscope tommorow and try it...is it a special automotive stetho. or any will do?

if it's the clutch bearing the noise will go away when you step on the throttle in gear when it engages.
if it's a constant noise then it's most likely the idler bearing. it's usually the #4 pulley that's common to have issues. i would suggest replacing it asap. you do not want it to seize and blow up while driving.

When I put it in gear it's loud but when I start moving it's gone, however when I'm at a stoplight and im holding the brake I can still hear it. Btw this only started happening as soon as i switched tothe code 3 pulley; If that helps. Where is the clutch bearing? Behind the code 3 pulley? How do I change it and who sells it?...frank if u pm your email I can send u a video if it helps cause I dont want this thing blowing up on me

guys the sound starts at about :38 seconds...let me know if thats what the noise from the supercharger clutch bearing is....and also if the squeal tht starts at 2 seconds and later goes away is normal...that squeal usually starts only on cold starts

The problem is that your belt is too long and it is causing the tensioner to bottom out causing the ratcheting noise. You need a shorter belt or you need to use a bigger pulley on one of the idlers.
