If you can do another quick Vid with light on the tensioner pulley just to see how steady she is, would be handy , thanks.I uploaded this but I doubt we'll hear my noise, may show the tensioner vibraion on the belt Hyundai i30CW D4FB chain noise - YouTube

Hopefully its there in vidThat's nice and steady. Going to be a process of elimination I'm afraid. Isolate the drive belt, if it goes then you'd spin each pulley for any roughness. I guess you've never taken the belt off yourself before either. Take images of how the belt is routed too before youtake it off if you decide to remove it. Does my head in every time trying to remember.Motor sounds pretty good otherwise.if the sound remains, likely internal, does sound very similar to what I heard like something rotating and travelling at the chain end of the motor.Sorry I can't be more specific or offer any solid advice.

Havent taken off a belt before, but willing to give it a crack and see how she goes and see if the sound is still there.
Just dropped in briefly because I see all this well intentioned advise being given, based upon an inaccurate microphone being waved around. Use a stethoscope!!@Misha get a short piece of hose, put it to your ear and move it to the place of the noise. Then if necessary remove parts, then do it again.

One for workshop and other for wife who recently found a dead cyclist during her early morning walk.
It won't help the dead cyclist!

$150 is a bit of overkill. I thought you said the belt had just been done?I'll have a look at that kit to see what it includes. Torx 40 I think, getting in there is awkward, I use a 1/4 drive with 1/4 socket with the bit and just fits. Bit of tape on the 1/4 end of the torx so it don't fall out of socket and drive you nuts fining it in the under tray.Maybe a torx key but avoid those cheap chromey looking ones at supercheap. One good slip of the torx and the torx slt can round and then it'll be less fun like rounding a philips screw.Is the plastic idler at top the noiseiest?Some threads are normal right hand, some are left. , example tensioner pulley, right turn to loosen, OEM belt should be 5PK1815, I think you'll see other sizes suggested just because that brand does not do that size

Was getting ahead of myself i guess From what i could tell (using the diagram from before) the top right IP was the most noisy out of the bunch, followed by the other IP middle top. Tensioner pulley was the best of the 3.From spinning the other wheels they all seemed good. alternator spun smooth and true IMO
One other thing, there was some disagreement on the direction of the bolt in the tensioner, so for the record, both of mine have 14mm std hex head, thread is left hand, clockwise to loosen. I've just checked this on my spare engine.Some of these have torx heads, they may differ I can not be sure but I'll see if I can find the thread where basically I said left thread, he said right thread. He had the torx headed bolt so be warned. Drive belt tensioner pulley
Pulleys came in mail today Was able to replace the 2 idler pulleys easily with a torx 40(only knocked off 1cm chunk of skin... ) , they where both anti-clockwise to loosen.Grooved ilder pulley was only a little noisy. But the flat, top idler pulley was noisy AF, so bearing was definitely shitty.However I was unable to get the tensioner pulley off, was a torx 30. Its on there well and truly, the cheap torx keys i got ( ToolPRO Long Hex Key Set - Metric / Torx, 18 Pieces | Supercheap Auto) started to bend at the tip, and the bolt maybe threaded like 5% (not much but enough to stop me).Problem is my torx socket set i have ( Kincrome 11 Piece 1/4, 3/8 And 1/2" Drive Spline Socket Rail) doesn't fit in the gap (unless anyone knows of a 1/4 ratchet thats skinnier than my sideways fingertip :/ )Started cold engine up, noise is still there, tho definitely less noise, the distinct original wobbling noise is still there, upon further intense continued looking at the tensioner pulley, the noise definitely appears to be in rhythm with the tensioner pulley slightly going back and forth. New short vid : ( Tensioner pulley noise ? - YouTube)Anyone know of a skinny ratchet and torx socket out there ? Or if its seized do i have to buy the whole belt tensioner unit to replace it.
