i just got my r33 back from having the water pump and timing belt replaced

now the car is making a whiny rattling noise that was never there before, its worse when its idling and just sounds like its running crap

was thinking maybe they did the tensioner too tight or something?

anyone got any ideas? and could i be doing any damage to the engine driving it like this? :(

Theres not a lot to chose from for bearing noise, cambelt tensioners or alternator/powersteering pump/air con. You can rule out the latter by removing the appropriate belts and seeing if the noise is still there or by listening for bearing noise on each unit.

Chances are it is the cambelt tensioners if the cars done reasonable kms.

Before you got the belt replaced it would have been stretched making the load that is on the cambelt tensioners less and hiding any wear.

Now that you have a tight new belt and tensioners reset there will be more force on the bearings which will show up as a rattling noise if the bearings are on their way out.

And just to add, never had any probs with GATES belts, they make pretty good belts, Nissan don't make their own anyway.

Timing belt? Mine whined a little bit after replacing the idler, tensioner, and belt. (all stock replacements).

It might have been tight, but in the first month i'd imagine that the belt would slacken off a bit, and you'd have to retension it. Mine has smoothed out and is fine now (4 months since change).

Only other thing that comes to mind is if they didn't do the tensioner up properly... the belt will slap against the cover, and whine as it slips past the bearing.

Remove the top-half inspection plate, and check that the belts seem really tight.. maybe even shine a torch down there to check it.

is it like a high pitched noise? (like its there when u start it, and when u press a bit of gas or if ur stationery) if it is, then maybe the belts are a bit tight - I had the problem when mine was changed - its a quick fix 15 minute job

Take it back.

Did you get tensioner and idler changed when the timing belt was done?

It may be air-con tensioner bearings or others, but there should be no noises.

hmmm, well i bought the parts and only got a new belt, so id have to check that out..

Its probably a gates belt! ask them what kind they used. gates belts are crap! stick to genuine. That is if all your other cam gear is stock. who did it?

yeah all stock and mmm yes it is a gates racing belt, the blue one...

thanks for that, well its done 113000, so yeah will suss it out

You might have a baby caught in the belt, check under the timing cover for small fingers or toes.

LOL...quite the comedian

Hey! I saw your car at RE the other night when I went to pick up my car! Rays a good guy, he will fix up the problem.

hey, yeah he is, i actually asked about it after i started it up while i was still there and heard the noise, he said it should be fine and could last till next service, but yeah i just dont want my car sounding like that for the next 5000kms so id rather have it fixed, watever it is and yeah dunno wat to do yet

Sounds like the belt might just be a bit tight - its often the case with the new belts (im assuming here its the same problem that I had). It would die out in a couple of months - but it is quite embaressing driving a hot car when it makes a noise like that.

if its to tight (very common mistake) it makes a wir wir wir wir noise

if its to loose it makes a flap flap flap noise.

the belt tension adjustment needs to be as follows.

with the belt on and the tensioner not done up...wind the motor over to take up the slack in the belt. then simply lock off the tensioner. (thats what the spring is for lol :) )

hope that helps :)

Sounds like what I had after my timing belt was changed - its a 10-15 min job. Main thing is its nothing serious

if its just loosening the belt a bit, it can be done without having to remove the whole front. There is a cover underneath the car which has to be removed (can be done while the car is on the hoist), then its just a matter of using a spanner or socket spanner to adjust the belt.

Well, thats what happened to mine anyway...and there hasnt been any troubles so far...

I think your confusing the aircon belt with the timing belt, or at least one of the other two that run off the harmonic damper. The timing belt is located behind the timing covers which do need to be removed inorder to adjust the one tensioner which is also behind the covers.

The only idler that can whine/wir/squeel is the aircon idler which is obviously outside of the covers and sits below the aircon compressor.

and whoever said gates belts are shit is a moron :(

Ah - that might be it - yeah they didnt remove anything when they readjusted the tension..:(

      R33 Fuel Pump & Brakes after alarm swap

      Who did you have do the installation? I actually know someone who is VERY familiar with the AVS gear. The main point of contact though would be your installer.   Where are you based in NZ?

      R33 Fuel Pump & Brakes after alarm swap

      Look, realistically, those are some fairly chunky connectors and wires so it is a reasonably fair bet that that loom was involved in the redirection of the fuel pump and/or ECU/ignition power for the immobiliser. It's also fair to be that the new immobiliser is essentially the same thing as the old one, and so it probably needs the same stuff done to make it do what it has to do. Given that you are talking about a car that no-one else here is familiar with (I mean your exact car) and an alarm that I've never heard of before and so probably not many others are familiar with, and that some wire monkey has been messing with it out of our sight, it seems reasonable that the wire monkey should be fixing this.

      After market rear camber arm adjustment

      By GTSBoy · Posted

      Wheel alignment immediately. Not "when I get around to it". And further to what Duncan said - you cannot just put camber arms on and shorten them. You will introduce bump steer far in excess of what the car had with stock arms. You need adjustable tension arms and they need to be shortened also. The simplest approach is to shorten them the same % as the stock ones. This will not be correct or optimal, but it will be better than any other guess. The correct way to set the lengths of both arms is to use a properly built/set up bump steer gauge and trial and error the adjustments until you hit the camber you need and want and have minimum bump steer in the range of motion that the wheel is expected to travel. And what Duncan said about toe is also very true. And you cannot change the camber arm without also affecting toe. So when you have adjustable arms on the back of a Skyline, the car either needs to go to a talented wheel aligner (not your local tyre shop dropout), or you need to be able to do this stuff yourself at home. Guess which approach I have taken? I have built my own gear for camber, toe and bump steer measurement and I do all this on the flattest bit of concrete I have, with some shims under the tyres on one side to level the car.

      R33 Fuel Pump & Brakes after alarm swap

      By Jarsky · Posted

      Thought I would get some advice from others on this situation.    Relevant info: R33 GTS25t Link G4x ECU Walbro 255LPH w/ OEM FP Relay (No relay mod) Scenario: I accidentally messed up my old AVS S5 (rev.1) at the start of the year and the cars been immobilised. Also the siren BBU has completely failed; so I decided to upgrade it.  I got a newer AVS S5 (rev.2?) installed on Friday. The guy removed the old one and its immobilisers. Tried to start it; the car cranks but doesnt start.  The new one was installed and all the alarm functions seem to be working as they should; still wouldn't start Went to bed; got up on Friday morning and decided to have a look into the no start problem. Found the car completely dead.  Charged the battery; plugged it back in and found the brake lights were stuck on.  Unplugging the brake pedal switch the lights turn off. Plug it back in and theyre stuck on again. I tested the switch (continuity test and resistance); all looks good (0-1kohm).  On talking to AVS; found its because of the rubber stopper on the brake pedal; sure enough the middle of it is missing so have ordered a new one. One of those wear items; which was confusing what was going on However when I try unplugging the STOP Light fuses (under the dash and under the hood) the brake light still stays on. Should those fuses not cut the brake light circuit?  I then checked the ECU; FP Speed Error.  Testing the pump again; I can hear the relay clicking every time I switch it to ON. I unplugged the pump and put the multimeter across the plug. No continuity; im seeing 0.6V (ECU signal?) and when it switches the relay I think its like 20mA or 200mA). Not seeing 12.4V / 7-9A. As far as I know; the Fuel Pump was wired through one of the immobiliser relays on the old alarm.  He pulled some thick gauged harness out with the old alarm wiring; which looks to me like it was to bridge connections into the immobilisers? Before it got immobilised it was running just fine.  Im at a loss to why the FP is getting no voltage; I thought maybe the FP was faulty (even though I havent even done 50km on the new pump) but no voltage at the harness plug.  Questions: Could it be he didnt reconnect the fuel pump when testing it after the old alarm removal (before installing the new alarm)?  Is this a case of bridging to the brake lights instead of the fuel pump circuit? It's a bit beyond me as I dont do a lot with electrical; so have tried my best to diagnose what I think seems to make sense.  Seeking advice if theres for sure an issue with the alarm install to get him back here; or if I do infact, need an auto electrician to diagnose it.

      Then, shorten them by 1cm, drop the car back down and have a visual look (or even better, use a spirit level across the wheel to see if you have less camber than before. You still want something like 1.5 for road use. Alternatively, if you have adjustable rear ride height (I assume you do if you have extreme camber wear), raise the suspension back to standard height until you can get it all aligned properly. Finally, keep in mind that wear on the inside of the tyre can be for incorrect toe, not just camber
