Hey guys not really sure how to explain or ask this but here goes;

The car SOMETIMES im not sure how to make the car do it again but it will randomly every now and then some drives it wont some drives it will.. in tiptronic mode going from 2nd gear to 3rd gear when i shift it will have a massive squeak noise i believe to come from the back.. i hav argued with mates taht its back right but some say back left - either way its from the back we can agree on this -

The sound started off as a little squeak... its really high pitched and now its getting louder to the point where over my exhaust, sound system and general conversation i can hear it and it gets alot of disgusted loooks from others on the sidewalk etc when and if it does it..

The car will also do it sometimes when im in high rev's in 2nd and coming to a stop at lights as the rev's creep down it will give a sligh jolt and hey presto theres the high pitchd squeak again..

one day i was at lights and decided to stick her in neutral and give it a little rev.. and it did the high pitch squeak again..

as i said it randomly does it some days it wont do it at all some days it just wont stop... and i dont know how to make it do it.. i hope this is making some sense does anyone know what it could be its really bugging meeee!!!!

:happy::):):down::down:

are you sure its not a belt slipping? i cant think of anything in the bac that might make such a noise, and sometimes its easy for noises to sound like they are coming from places they arent, one time i was sure that my ac compressor had threw its bearings, cos of a loud scraping noise (also got some disgusted looks!) but turned out to be a rear brake pad stuck on and wearing thru the pad

i recently had a car with a slipping drive belt and it would squeal in almost the exact same situations u have mentioned

i suggest you try a can of that sticky belt spray stuff just to quickly and cheaply eliminate or target the problem of a slipping belt

and if it squeals when reved while sitting still in neutral i dont see how any squealing noise can come from the rear of the car, has anyone had a listen while outside the car??

nah mate no one has listened from outside the car because i dont know how to make it do it again lol :happy:

for example today i was driving with mates it did 3 massive ones in a row and kept squeaking away a few more times... stopped parked the car for a bit had some lunch and a chat and drove it again all arvo and it did it once again only so its pretty inconsistent..

and yeah u may be right its probably not from the back but it surely does seem like it.. as it gives a slight jolt and the squeak when going from 2nd to 3rd as i said.. i dunno but yeah man thanks ill check out what you said and hopefully that shed's some light

cheers

yeah man...im not to familiar with the tiptronic, mines a manual...and my other car that had the slipping belt was a manual, and would squeal often when changing gears up or down due to the changing loads and speeds of the motor versus the rest of the car

...but usually with the belts its pretty clear that its coming from the front, i just cant think of anything else it could be, does the 'jolt' pull the car foraward or let it slow backward?? cos i would attribute the 'jolt' to be the belt catching and griping and thus puling the car forward again or slipping and letting it backward

like i said i dont know anything about the tiptronic but i cant think of any parts of it that would squeal or squeak, after all, isnt it just gears controled by electrical signals from the paddel shiters?

ok so ive put it down to when i have my climate control on (aircon or heater etc) then the squeak is very loud even if i just rev it in neutral or park also when im driving... when i have climate control off it hasnt done it lately??

Have you changed your timing belt n idler tensioner pulleys before it happened? When I done mine I got a high pitch screech sound in higher revs n even when revving in neutral, but only when I had climate control on. I took it back n they just adjusted a couple of belts n problem gone. Just when you mentioned climate control it sounded similar to the issue I had.

i get this thing here and there to o.o exactly what you said Nathan. higher pitch squealing sound when the revs goes up, especially above 4rpm... but i also noticed it usually only happens to me at night time? and i never use the climate control... is my thing related or.... lol

well i tested the theory out tonight with mates.. and its definatley only happening when i hav the air con fan switched on.. with it off it doesnt do the squeak but when its on i can sit ther rev it up and at about 4500 - 5000 rpm it will squeak from teh front...

It's the belt slipping as the aircon compressor kicks in. Mine used to do it at higher revs but it can still happen at lower revs- you just may not hear it. Ask a mechanic to tighten the belt if required and it should all be sweet. Alternatively the belt may be old and need to be replaced.

    • Hello, everyone. I'm new to the forum. I have a 1989 Nissan Skyline R32 GTR. I have lost all power to the interior, including AC controls, the gauge cluster, turn signals, and windows. Stuff that still works includes the horn, brake lights, radio, and headlights. All fuses, in the interior and exterior boxes, tested good.  It starts and runs fine, just with no gauge power or anything stated above. No warning lights either. Things that I have tested: - Fusable link tested fine - No other fuses blown - Alternator good - IGN switch tested fine - With my power probe, I can backfeed power through the IGN pin to the plug on the back of the gauge cluster, and everything comes back on.    So my theory is something on the control side that sends the ignition power through the system isn't doing its job, or a wire is broken. (I would think that it is the ignition switch that would do that, but who knows?). The ignition relays don't fire (all relays tested good). So what tells them to fire other than the IGN switch?  I would really appreciate it if someone had some insight on this. I have tons of hours into this; I don't want to give up in defeat! I have the HD wiring diagram, but having all those wires laid out like that on one sheet of paper makes things pretty hard to follow.  Thanks for reading, and thanks for the replies.  Where should I look next? Thanks.
    • Install a MAP sensor pre and post throttle. Best data you could have for NA, then play with the bends and/or air box and see how much of inflection is created at WOT on the plot.
    • And gone to a new home  
    • The car remains in paint jail. I am now pretty convinced that the whole "RB25 Airboxes are kinda limiting to ~300kw" could be a thing. Also saw a good video from Engine Masters: (Sorry for FB link) (https://www.facebook.com/watch/?ref=search&v=761771519471924&external_log_id=c10bcbb6-2c39-4ff3-9240-287e9921fde6&q=Cold Air Considerations) Where they tested Pod Filter sizes and kept adding bends to a LS3 on an Engine Dyno to find if bends caused power loss. It's a good video worth watching - They did lose ~25hp from making an intake which had 3x90's and a 120 degree. They only lost maybe 1hp with a basic 90. I feel that by sealing up my airbox I have: 1) Created the same restriction a stock airbox would have. 2) Created a very convoluted set of intake 'pipes' by forcing all the air through the ducts. So I am pretty confident I'll be going full circle and have a huge hot air intake pod and actually see a benefit. The air does *not* stay hot once it gets flowing, aided by the ducts, and the pod can then pull air from anywhere. All the posts of yore talk about the stock airbox costing 10-15kw at 300kw+ but you know what? I f**king would very much like that 10-15kw and I remember my own pod filter in engine bay experiences. Turns out the GTT Reo and Headlight brackets really don't allow you to mount GTR items, no matter what the internet says. Various brackets have had to be made up to actually make it fit right for the front bar. Also some idiot mounted a 3L Accusump right where the bumper wants to go, so that has had to be 'relocated' To where, I am still not sure, but it's supposedly mounted in the pictures and I can't see it.
    • Sounds like the oil pressure light is wired into the oil temp sensor... As it warms up, resistance on temp sensor reduces, hence more current can flow and the dash light gets brighter.
