Timing belt noise?!

Hello!

I just recently had my Timing belt done and all the accesories, tensioners/pulleys etc. The shop who did the job is very reputable and have done many jobs like this before.
So when I got my car back I didn't notice anything, the car sounded fine. Drove it home, (3 hour journey) and just as im arriving when I do a pull from 1st gear in the parking space I hear a whinning noise from the engine? Was pretty tired so decided to look it up the next day. I read through some forum posts with people who experienced similar problems. That their belt would make squeaky noises, when warmed up mostly and around idle. In my case this is what i've discovered so far: Noise is there both when the engine is cold and warmed up and only seems to be apparent from 1000--1500rpm. Anyone have any ideas what this noise can be?!? More frustrating than anything!

The timing belt kit installed is a Blueprint oem replacement.

Unfortunately non OEM belts can be noisy.

My V-Spec II had a Gates belt on it and it was ridiculously loud,

Another GT-R I had had a very expensive competition belt on it and it was even worse!

Both were replaced with OEM and they were as quiet as a mouse.

You simply can't beat a genuine OEM Nissan belt from Nissan for noise.

I have a Gates racing belt on my 34R. Sounds very similar to the video you posted. As people have said, aftermarket (gates) are notoriously noisy.

My Gates has been on the car now for 20 Thou K's. No issues

(Update) We loosened everything up, starting with the easy stuff, servo, ac, and so. Noise was still there so we removed the timing belt. Then discovered that the tensioner pulley had residues of rubber on it from the belt probably? So the tensioner pulley was taken off and inspected for damage but seemed fine. Everything was removed and installed back together.

So my guess is the belt was put on a little bit too tight. The tension was doubled checked. Anyway the car is much quieter now, but I can still hear a small belt noise on idle but it goes away when the car warms up and introduces another sound (when warm) when you rev the car and it drops off at 1000rpm.

Overall I reckon the car is quieter now than before but not perfect. Guess i'll just have to drive it for a while and see if it goes away and if not, I may replace it with an Oem Nissan belt.

Same issue on my R33 S2
Timing belt done at 140ks, factory belt... Purred like a kitten before.

Approx week after getting it back it developed the exact same noise.

Was told that it maybe evident prior to even getting done and sure enough it turned up a week later.

As we all find out OEM just can't be beaten for it.

Pretty sure mine was a gates belt.

      Pops when backing off throttle, rough-ish sound through rev range.

      By AdiR34 · Posted

      Yes to both! Yes to standard ECU and tune, but exhaust is aftermarket. Unsure on brand. Actually have it sitting in at my desk haha! I have to set it up on my laptop but this is a great next step, will do. So I generally try to shift before 4.5K RPM most times. I largely don't do a lot of high-rev driving, but I will take it up to red 1-2x a week max, as I know the occasional "Italian tune-up" is good for these cars.  Oh wow, is this way better than what I'm getting. Does this mean there's a good chance I have an issue?   Thanks for all the info so far guys.

      Old Son, did you re-use the Holden ABS in the new shell or try a different module?

      Another little story of weird shit happening

      By GTSBoy · Posted

      Yeah, nah. I had the actuator rod off it today. The arm will not move at all. Neither out, nor in. Yeah, you'd think so, but I've been thinking about that. Even when the actuator rod fell all the way off at the beginning of this saga, it would build more boost and faster in lower gears than it would in higher gears, and you'd think that that was the opposite of what should happen. But I strongly suspect that there is a thing with the gearing getting the revs to rise faster, that there must be some transient effect with the gas flow rate rising quickly, that you don't get with the more steady state case of the higher gears. Keep in mind - the gate is not shut in either of my weirdnesses. So things are not "normal". We normally think about a turbo spooling up (below the wastegate target) with the gate shut. I have all sorts of mental models running now where the gate is a little bit open, and having it stuck open allowing gas out while it should be going through the turbine has all sorts of weird effects (in these mental models). I'm thinking in the higher gears, the ex mani pressure builds to the point where enough gases spill out the wastegate to just prevent the pressure rising much more at all, or just creeping up, all the whole the revs are increasing and getting closer to the point where a gear shift becomes necessary.

      Is it possibly wastegate actuator itself is sticking, or even the rod to flapper? Otherwise I reckon things are getting a bit rusty/worn   Also odd it won't boost in 3rd to 5th, but will in 1st, I'd expect the other way around with it slightly open as there's more time on your way to redline for it to spin up
