Need Help: Funny Noise From Front Of Car

Hi all

Over the last few days I have heard a strange sound coming from the front passenger side of the car.

This only seems to occur under acceleration/ pressure.

It sounds like a rapidly tweeting bird or a rapid squeak (sorry of the bad description). It could also be explained as high pressure air having something waived in front of the flow.

When I had the 3in zorst made the guy said that there was a bolt missing on the zorst manifold. At first I thought it could be just leaking pressure, then thought it was the turbo but now I fear it could be something else. A mate just said it sounds a bit tinny to him….????

Don't have a clue???

Any thoughts???

Check all pipes for leaks? Could be a cooler pipe leak? Same with exhaust?

Or pinging? best way to describe pinging from me is like put a small stone in an empty coke can and shake it inside your engine bay...?

After asking a mechanic mate:

Could be something loose or broken and rubbing, like a motor/gearbox mount, or a tailshaft?

If it is only happening under load, then it is being caused by the load, or associated under load variables (eg increased airflow), or torque twist.

Not a stupid question

Yeah the sound is different to a spooling turbo…..The funny thing is it doesn’t do it all the time.... sometimes when I try to accelerate harder to hear it again trying to suss it out it doesn’t make the noise….

It’s not pinging, I know that 

I think you could be onto something about the broken or rubbing of a part but don’t think it’s a tailshaft or mount….

Definitely only happens under load but as said above its not constant….

Will get the bolt sorted on the manifold this weekend get new manifold also just in case and check all pipes etc… wonder if it could be the air box as I put it back in from having a pod in there???

Really stuck!!

Heres a stupid question… my charcoal canister is loud as a mofo… could it be playing up under load ??

sorry should have just said it makes a (loud) rattling noise

Could be not bolted down tightly, maybe? You sure it's the canister? Sounding more like something is definatly loose.

Anyone thought about the climate control unit? this is located in the front passenger foot well. a belt or fan motor could be loose or have come away from something else. i'd dig around there and see if that's the problem

Yeah could be loose/slipping belts, good point Leshy!

I personally have never heard any noise from my stagea or my skyline canister, although I have never really tryed to listen specifically to it before either....?

Honestly I wouldnt have a clue, all I know is what I have heard from mates and stuff. Have been told that all it does is filter out the petrol vapour out of the air venting from the fuel tank so that it does not vent to the atmosphere....?

But hey I am by no means a mechanic, just offering suggestions...? :P

      Rv37 400r questions

      By elir32 · Posted

      Hey guys. I have a 400R on its way to Australia from Japan currently and have a few questions I’m hoping others may be able to help with.   Wondering if anyone here has had any luck getting the Sat nav unit to work in Australia!? Assuming the Stereo is as simple as a band expanded and tv won’t work?  Seeing as they’re based off a Q50 which is Aus delivered is there any way to link that system to the nav? Nav modules and head unit are different part numbers and appear slightly different at the rear with plug ins etc. can I put my xtrail sd card into the rv37 and will that convert the maps or update to Australian? Has anyone got any advice here?     also has anyone fitted the factory remote start and Security system once it’s landed in Australia? I put an enquirey to Nissan Japan in via a third party, and they suggested it needs a Nissan Japan dealers device to setup and couldn’t guarantee if one here could do it or not. They can supply and I can physically fit it but to setup I would need a dealers device. Any information here would be appreciated also. I’ve seen one here with it fitted already prior to leaving Japan at a dealer/inporter, so clearly passes compliance and works when fitted Japan and doesn’t need changing here.      also, does the tyre inflation sensors work here? Does anything change with them when the vehicle arrives? Where are they actually situated? I’ve read they have batteries and they need to changing at times and seems like resetting involves the nav system?    any help here would be appreciated and any other aust specific information to help would be great. Looking forward to see what the current generation skyline is like and eager to see how many of the gadgets can be utilised here.  Thanks in advance

      Do need to take it with a pinch of salt. One of the adapter failures, they clearly had setup issues with the flywheel.  One of the slipping ones I spoke to and it was pretty clear the throwout was riding, rather than fix, just swapped to a new clutch.    These clutches are being put in anything from 5k offroad 4x4 beaters, GR yaris, 500hp commodores to 1200hp barra monsters. Bound to be some issues in some of them when they are not a simple bolt in affair due to the changes in height.    There is a lot going on in this picture and unless I did the job myself no way to tell what really happened.

      R34 GTT Battery Relocation To Trunk

      By NZ-GTT · Posted

      I did this mod in 2019  You just have to modify the top bracket of the ABS/TC/Fuel Pump Control ECU so it sits more upright and closer to the back seat and run a good quality positive battery lead from the engine bay, the negative lead i just bolted down to the body in the boot.
