Buzzing sound from rear on start up? R33 GTR V-Spec

Hi All,

I’ve done a search and couldn’t find anything on this specific topic.

On startup I have this weird buzzing sound from the rear of the car which goes away in about 10 seconds.

It’s definitely not the fuel pump. Sounds like something 4WD or HICAS related pressurising? It can be heard intermittently for about 2 seconds every 30 seconds or so after the first “prime”. 

Is it a normal V-Spec thing, or am I losing pressure somewhere?

Hope someone can shine some light on this.

Thanks!

Atessa priming. 

So this is normal?

It does it every 30-40 seconds for a second or two after the first prime.

This is my first GTR so I know nothing about what’s normal or not lol.

You should be happy that's all you hear.

Just imagine in 1995, all these whizzbang fancy electronic stuff clicking and buzzing away while your neighbours had to pull a lever to prime their carburettor.

Very true!

I had the same issue on my GTR. Change the Nitrogen canister on the atessa pump and bleed the system ( you can search for a how to )

Just jap sell the part.

Hmm ok, so there is a problem then? I’ve read that the nitrogen canister causes the relays to click, haven’t heard anything about the canister and my issue till now.

So you had the same issue and replacing this fixed it? As in doesn’t make intermittent buzzing noises now?

Just want to be sure before I spend ~$480 on this!

The buzzing noise on my car was the atessa pump running. the relay will click on to turn on the pump.

If you start the car lay under the back of it and listen to the pump. if it turns on and runs every 30-40 sec then the canister needs changing.

      How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP

      Jacks that fit under GTR lips that can reach the subframe?

      I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use

      I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.

      You are all good then, I didn't realise the port was in a part you can (have!) remove. Just pull the broken part out, clean it and the threads should be fine. Yes, the whole point about remote mounting is it takes almost all of the vibration out via the flexible hose. You just need a convenient chassis point and a cable tie or 3.

      ..this is the current state of that port. I appreciate the info help (and the link to the Earls thing @Duncan). Though going by that it seems like 1/4 then BSP'ing it and using a bush may work. I don't know where I'd be remote mounting the pressure sender... to... exactly. I assume the idea here is that any vibration is taken up by the semiflexible/flexible hose itself instead of it leveraging against the block directly. I want to believe a stronger, steel bush/adapter would work, but I don't know if that is engineeringly sound or just wishful thinking given the stupendous implications of a leak/failure in this spot. What are the real world risks of dissimilar metals here? It's a 6061 Aluminum block, and I'm talking brass or steel or SS adapters/things.
