Car is a S2 R33 GTS25T Manual... Everytime I start the car there is a reaaally loud screeching sound coming from what seems to be under the car on the driver's side. Definitely not the fan belt... it was coming from what seems like the rear of the engine bay. But after the initial noise, it goes away... any ideas? Thanks!

timing belt maybe loose ..... when i had a new one put in it stretched and came loose ....i sent one of the apprentice mechanics to investigate ... my car was parked two blocks away the mechanic started and my boss goes "Geezus what is that sound?" it was that loud! so get it checked cos you dont want it falling off!

Starter motor

could be on its way out.. could have dust in it.... best to get someone to look at it...

This is what it most likely is. Quite a common problem in skylines. Not a big deal. Starter motor MAY be on its way out but most likely has dust in it and will still last.

It wouldn't be a slipping timing belt, cause if that slips your engine will go by by....

Just sounds like a slipping fanbelt, nothing more serious than that (My RB25 180sx does the same thing every time I start it up, I just havn't been bothered fixing it yet!).

Ok, finally got it sorted out.. so it indeed was the starter motor. My Japanese is crap but it was something about the starter motor sticking in longer than it was supposed to.. causing the noise. Just needs to get cleaned and greased up again and it should be ok. thanks for all the input!

oh and just for anyone reading this in the future the sound was coming from what seemed to be like under the driver's side of the car.

Ahh took it to the dealership that I got the car from (here in Japan). I got a year's warranty with it so it isn't costing me anything..but from what I've heard it shouldn't be too much. I didn't take it out but perhaps if you did and then brought it there it would save you some $$ on labor as all they would have to do is clean/rebuild as opposed to taking it out themselves (which can be a pain if I read correctly). Don't know why but they wanted it there for two full days so I pick it up tomorrow. I think that's more because they were backed up with lots of cars.. not because it really takes that long. hope that helps.. good luck!

My 1991 r32 GTS does this about every 5 starts.. almost sounds as though i'm holding the key on too long, but i'm not..

Might try checking the slackness in the belts, anyway just to make sure

if the front bush in a starter lets go, its metal rubbing on metal. As for sticking in, the solenoid on top controls that, so either your voltage may drop (ups the amps drawn to compensate) and arcs the contacts together, or there is a starter relay in your car somewhere thats a bit sticky.

      Looking for a part number for this part here

      By eli995 · Posted

      (Rb25det intake manifold) I’m having a hell of a time trying to find the full part or part number of this coolant hardline so far I was given these (Below) but they aren’t what I’m looking for and was told it’s the IAR or aac valve but that doesn’t seem to be it either. If someone could point me in the right direction it’d be greatly appreciated. Or if anyone has it for sale that’d be great too. I have recently purchased a greddy manifold and I can’t seem to find my old one to pull it off.  (Front Heater Return / Water Pipe (under intake): Primary part: 14053‑21U10 (front return pipe assembly for R33/R34 RB25DET) Alternative listing: 14053‑21U00 (same pipe, sometimes interchangeably referenced)   Heater Feed Pipe: Listed as 14075‑04U00 or feed-related variant 14053‑AG500)

      This sounds cool. But, as per usual, anything really complicated like that, that I take on, constitutes a steep learning curve that I never actually "learn". I just get it working, install it and start using it. Then, when it breaks a few months later, I've got no memory of what I did, how I did it, or even the bloody IP address I gave it. I'm having more or less exactly that problem right now. My Proxmox machine was discovered to be non-responsive, and the VMs on it were ditto. Power cycle it to a stream of loud Dell beep codes - which was unpopular at midnight, I can tell you. Move it to the lounge room so I can HDMI it to the TV for a screen, see the boot messages complaining about the /PVE/data having all sorts of LVM problems, saying it needs to be fixed manually. And I'm like....great. How am I going to work out what I need to do? At least it wasn't the stupid Silicon Power SSD shat itself. Mental note for all readers - DO NOT BUY SP SSDS! They are shit. I have had one take out an entire VM setup already, and this one could have done the same. Maybe it actually has. Cheap Chinesium shitbaskets. I won't cheap out again, even on play projects with no budget. Because my time budget having to fix shit is worth far more than the cost of proper parts.

      I do typically agree. These days even the screens most people use have more of a boot time than the main device. However, I've seen an interesting use of the RPi in vehicle, however it involves effectively building your own OS and MBR, as then it boots up exceptionally quickly, as you don't have everything needing to start up, and you can then also run it up as an RTOS, while still having more compute than an Android can give for things like display, and processing. A very huge task that would be though for Duncan, I'm not sure that's his skill set (or Arduino programming and wiring) ha ha. If end goal is definitely just water cooling, Arduino would be the simpler setup especially for a rookie. If he wants extra display stuff though, bashing some code in Python on an RPi may be the better result for both systems.   Unfortunately the new device I'm building at work which runs a display, is too slow of a display for dashboard style purposes. More extreme low power, update only a couple of times a day type system

      I don't like "actual computers" for in car use. They take time to boot up, have OS annoyances, and so on. Arduinos etc are ready to go a few seconds after power on, don't mind being agressively powere cycled, because everything is non-volatile, don't mind being shaken and stirred.

      As Fred would tell us, it's all about interpreting the rules. It's not a water sprayer, it's a water mister... But everything else you've said, 100%! Even a raspberry Pi would be great, use HDMI out for a display, and add a raspberry Pi CANBus hat to read values out from the ECU.
