yo peeps

my mates RB25 (s2) is all of a sudden making a funny noise kinda sounds like a bearing

it was fine like a week ago, hasnt been driven.. now all of a sudden this noise

tried unplugging vvt but that didnt fix it, it feels like its coming from under the rocker cover

the engine is stock, unopened etc

take it to a mech. asap! i wish i had gone to see one earlier. i started hearing a similar noise, took it to my mech, turns out harmonic balancer had come loose... left it too long and had damaged my crank :D

hopefully this isnt your problem.

This is screwed... i have just changed the spark plugs... but i took it for a few drives and it never made any noise..

Then a couple days before i moved overseas i started the engine and it was fine no noises at all..... so i dno how a noise like that could suddenly come up?

worst of all is i now like in U.A.E and im trying to get rid of the car soon as possible.....

Could be valve guides in the head. :worship:

i dont see how the valve guides could make that noise?... i dont think its the valves themselves because i bent valves and it make a different sound to that..... so i dont think its bent valves.

if valve guide were stuffed... then oil would be getting into the cylinders and there would be smoke coming out the exhaust?

I hope it could just be the water pump?

otherwise what sort of bearings are in the head?

Idler pulley bro.

It sounds SO much worse than it is though huh? I crapped myself when mine started doing it. But with mine it went away after the car warmed up.

Check out my vid:

Same noise more or less. I changed my belts/idler/tensioner, goneburger :P

if your not sure take it to a mechanic that is..... to me it sounds like it may be a few different things so best to take it to someone that can u tell u for sure and pinpoint the problem before it gets worse....

could me your lifters if u say it started doing it after sitting there for alittle while.

the timing belt is due anyway so doesnt bother me or the owner to change it, he's giving me $100 to do it anyway :D

its not the lifters i know what they sound like

      Take the value it measured as, and pick the closest range available that is above the reading on the screen.   Also, no point just testing the coils. Read what has been said again. You need to test all your wiring, everything.

      R34 Handbrake light saying ON and intermittently flashing

      Does the scanner do all the CUs in the car, or only the ECU?

      R34 N/a And R34 Turbo (gtt) Transmission.. Uh, Problem.

      By albyz34gt · Posted

      @666DAN sorry to bring you and old thread.     I've got my de+t done and it's all running great other than 1 small issue.    Car has remained auto with the na auto and tcm, I've used a stagea ecu with. NIstune board and everything is great other than my gear selection on the dash. It illuminates park, reverse, neutral, 3rd and 2nd when selected . But nothing when in  drive or what gear your in when you pop it into tiptronic. I'm sure there is maybe 1 wire in the ecu plug I need to move to rectify this. Do ya have any ideas?     Cheers man

      Well I recently changed my rear axles and was thinking if I bumped anything, I have been driving the car for a while now though... But it has been raining today so everything is wet under the wheel arches. Brakes feel fine and can't hear any of the metal screamers, I had a squeak coming from one of the handbrake drums but that seems to have gone away a while ago. I was going down a hill when it lit up and I did feel the abs bite for a second and question why it did it?

      ECU sees many times the speed than speedo does (R34 swap)

      By GTSBoy · Posted

      Correct. Um. I dunno. I haven't cared enough about the way that the NA cars work to know for sure. But..... The 33/34 turbo manual cars have an electronic speed sensor in the gearbox that outputs a +/- (ie, sawtooth AC) voltage signal. That is connected to the speedo. The speedo then outputs a 0-5v square wave (ie, PWM) signal that the ECU (and any other CU on the bus) sees. The speed sensor is NOT directly connected to the ECU. So here's the problem. Your new ECU expects to see the PWM signal, but must somehow be getting a direct signal from the diff speed sensor. Which would suggest that the wiring of the NA car is not the same as the turbo cars. I think you will need to spend some time with (hopefully the wiring diagram for the car) and a multimeter to see what is connected to what. Then, presuming I am correct**, you would then want to separate the ECU speed signal input from the rest of the car's wiring, and probably either buy a speed signal converter, or build one using an arduino (or similar). That would take in the speed sensor signal and output a scaled (and suitably rearranged) signal for the ECU. ** We shouldn't presume that I am correct here, because there might be something else crazy going on. I don't think you could convert the speedo to be fed from the gearbox sensor, because the pulse rate from that sensor is probably different to the diff sensor and then the speedo would read wrongly. And this also wouldn't fix the ECU's problem either, because the ECU doesn't want to see the gearbox signal direct either (assuming that they are all on the same wiring, for some odd NA related reason, see above caveat!) Does this help? Probably not. Can you make it work? Almost certainly. With the above work. You should buy a handheld oscilloscope from Aliexpress so that you can view these signals directly. Connect up the probes and drive the car. Show photos of the screen when drving at known speeds and connected to different places, and we'll see what we can learn about it.
