Dephaser Pulley making slight noise

[Stephenx77]

Hi guys, I've had my 172 cup for 3 weeks now and I'm loving it . I have noticed though that after the engine has warmed up I can hear a slight noise from the dephaser pulley at idle and when I say slight I mean slight lol. You can't really hear it outside the car, but you can when you're in the car.

I was just wondering roughly how many miles you think its got before the pulley starts making a real racket and needs changing?

I know that the cambelt was only done a couple of years ago, so I don't see the point in paying for it all to be taken apart again until its really necessary.

Cheers

What makes you think its the dephaser??

Could also be carbon canister,injector,waterpump etc......

Theres no way I could have checked before buying as it only starts making the noise after at least 20 mins of driving and to be honest its such a slight noise I may not have even noticed it. I think its the dephasor because it sounds exactly the same as videos of engines people have diagnosed on hear as the dephaser, only a lot quieter. The noise also disappears after about 2k revs. The car only has 44k on the clock and the owner for the last 9 years was a 65 year old gent, so its unlikely to have been constantly thrashed. If the noise gets louder in the future I will have it changed, but for now I can't really afford to do it as I'm paying off the insurance

After reading up some more about this noise, it sounds like it could be the carbon canister. But if i reved the engine slightly from idle, would the knocking noise get faster if it was the carbon canister?
