Timing Belt Change Resulting In Noise?

[Ruxis]

Hey guys I got my 100k service done with the kudos kit. I got it done at a well known mechanic in the Wollongong area.

I lowered my idle revs the other day with the plastic screw (r34 gtt). The air flow one I think it is?

It was sitting on around 1100-1200 as that's how I got it.

I lowered it to the reccomennded 650 and since then I can hear a sorting of rubbing sound every now and then like it the timing belt?

Does this sound likely? Should I raise my revs? Take it back to the mechanic? Or is the belt just wearing in??

Yeah its sounds normal ....

Preety sure it's just the bearing in the tensioner wearing in from memory

I've had a couple of 100000 services done and no belt noise.They could of put it on too tight take it back and get them to check,better to be safe than sorry.

could me lowering the idle revs done anything??hmm i could be making myself think this but there may be a dip in power.oh really? hmm i like the first comment better then the second haha. i might give him a call.

I'm on my laptop and the sound is broken,trust me if it too tight the bearings get to hot and cook the grease in them and they sieze up,result shaved timing belt.

[Ruxis]

no not at all.it sounds like a rubbing, you can only hear it on idle.its not a squeak its a rub and it does it over and over while idleing, as if when something turns around its hitting something. if that makes sense. i could probly do a youtube video if need be.

Please take it back,mine lasted 15000 ks,cost me another big service.If you had no noise before this and now you have something is not right.And if the t belt snaps by by engine.

Ive adjusted my timing belt(gates belt) 3 times my self. First time it made a scrubbing kind of sound it was loud. Definitely too tight. Now its just down to a tame whirr which is normal if you are using a gates belt. A gates belt has almost no stretch and no room for tolerance. If you are running the belt too tight it will make noise right throughout the rev range as there is constant strain. Its a pain in the arse loosening it, pretty much everything off again just to get to the damn tensioner.

First time took me about 3 hours, second time to adjust took about 30 mins to pull everything off. I reckon I can do a full timing belt change on an R33 in about 1 hour now.

This is mine:

Most horrible sound my car has ever made. Its gone now and as I said just a faint whirr.

[Ruxis]

what do you think of the noise sarge? or anyone?

[Ty1]

simple solution, piss off the gates and get a genuine nissan belt! I had so many dramas with my previous skyline and the gates timing belt. All the mechanics I took it to said that it was normal and to let it 'wear in' and the noise would disappear. 8000km's later and it was still making that humming noise.

[Ruxis]

hmm that sucks...what if your engine blows? would a mechanic have to replace it?

I have one of these belts on my own car as well, there are two different gates belts as far as i am aware, the one i have is the "race" version and is blue, it makes a light whirring noise, although your seems louder, or it could just be that my car runs a solid top end and jun cams which are quite loud and it may not be as noticeable.

provided the tension of the belt is ok, i cant see there being a problem, apparently very strong belts, hence the noise, but i wouldn't buy another one, the nismo seems to have the best rap, or genuine

[Ruxis]

It is the blue one.

Would you take it back??

Just want it fixed zzz hah

100% belt noise, its definately tighter than it should be. Ill get a video tomorrow of how mine sounds. Its not loud(sometimes when warm it CAN get a little audible) but definately not that noticeable. It is if you stick your head under the bonnet.

And why the hell would you remove it? Adjust the tension, thats it. They are great belts, better than Nissans. Nissan belt is softer so it stretches a tiny bit to give the belt a tiny bit of play room. Get this tensioned right and she will be fine. Its not going to break, its not gonna snap, its not going to kill your engine if its fitted right. Noise is noise, its normal.

Get it adjusted and after a while you wont even notice the tiny whirr. Its inaudible from the cabin.

Alright sounds good. I'm taking it there tomorrow so he can look at it
