Checked your oil and made sure the pump is working? We were cruising around in a friends car and it started ticking pretty loudly, we thought nothing of it, then 5 minute later we had a seized engine.

Not meant to scare you, but better to be safe than sorry!

did it all of a sudden come on or has it been a gradual sort of noise over the months/years... It could be a noisy lifter so maybe u should give it an oil flush when changing oils, otherwise maybe it could be the oil pump? Either way i'd check it out asap as rebuilds aren't cool.

Guys,

try the old screwdriver test. What you do is get a long/large screwdriver, with the engine running, CAREFULLY place the blade of the screwdriver against various parts of the engine or on the components bolted to the engine and then place your ear against the butt end of the screwdriver and listen for excessive noises. If you're unsure how loud the noise should be check the same spot on a mates car. Good way to isolate a noise to a certain area.

JUST BE CAREFULL !!!

The NVCS solenoid on my car goes spastic every now and again. Makes a great clicking sound, sounds similar to a popcorn machine at full tilt. Just by holding the back of the solenoid where the plug goes into it stops it, just too lazy to fix this on a more permanent basis.

hahahaha i like ur style:D

the ticking whilst cold , as said above is the lack of oil in the top end so lifters will tick.

not too sure with skylines but in the vl , hydraulic lifters always after years of use seem to tick , and take a while to "pump up" when cold.

a water pump most likely wont make noise at idle , it is more a load thing , hold it at 3k revs , in neutral , and listen for a definate clunky noise , more evident than a tick noise.

sounds similar to a thrown big end bearing.

injectors make a constant tick tick tick , be it hot or cold , day or night.

injectors/lifters tick (probably a dupe but i cbf reading all the posts :()

mine does that fairly audible on idle with bonnet popped and head in engine bay, but if its from in the car whilst accelerating, more than likely u got a missing exhaust manifold bolt like me, dont worry about it unless it starts getting worse or the cars feeeling crap/doing something crappily noticeable :)

    • Actually looks like a Nitrous setup now 馃槅
    • @robbo_rb180 I already have a NEO head on the shitbox 馃槑 Just needs beehive springs so I can rev it past the 8600 rpm limiter, then again pointless too, turbo is out of puff lol. Wen da gods let me win lotto eh?
    • Everyone I know with a90 supra at time attack aren't having issues with 3-5 fast laps so far and one is decent powered one too. Saw a k24 swapped 86 with a 8hp70 and big slicks and aero which had no drama's at QR and Manton Park. I've stuck a 25 row cooler in my setup with 8hp45/50 in the hopes of keeping the oil cool as I plan on some racing next year that 20-30min sessions. I've also geared my car so won't be using 7th and 8th gear too. @Dose Pipe Sutututu just needs to get that samsonas in already and have that tassie guy fit a head and rev it too 11ty thousand rpm. 
    • My embedded systems thoughts have me sitting with GTS on this. Variation between same phone hardware, should be small. However, the internal "intensity" or "volume" amount that say Google passes to the app, will be quite different, as the underlying hardware will be passing different levels for the same volume to the Google OS. Until the app creator has had each individual phone, and set benchmarks and calibrations for each, the amount of error can be quite huge.   It can even be observed by using different phones, recording the same noise, and then playing it back, they end up soon ding different. A big reason for it, is even the different types of mics used in phones have different responses, and different frequency ranges. Then you need to get into the DSP, and the variations in those, their sample rates which then effect their frequency range, and then the quality of the DSP, and what type of hardware conversion they do to for the ADC within the DSP. Oh, and let's not forget at the low level phones are designed to cutout loud sounds. It's one of the reasons they suck in really loud environments (eg concerts). The louder you yell, the more you'll get cutout too Note DSP is Digital Signal Processor ADC is the analogue to data converter. I don't have any real data on what the variation would truly be, however, chat GPT says in general, their output is typically between +/-2dB to +/-5dB of what you're really measuring. So realistically, anything from 4 to 10dB variation is possible even with the same devices.
    • 'sif the error will be that low!
