hi all,

i have noticed that im hearing some noises at the front right (passenger) side where the power steering pump is.

my car is r32 1993 skyline turbo with 86556klms.

sounds like fan belt sounds but it aint ..coz the belts are still good ( but may need replacing due to klms.)

could it be:

*the power steering pump (which i think its not coz fluids are not being drained nor steering doesnt make noises when i fully turn right or left)

*the 3 belts ? (but still looks good and still has thread)

*the buttom tensioner pulley? (when i get below the car to listen to the noise it sounds louder and *seems* like its the bottom aircond tensioner pulley)

*the air cond compressor bearings? (i currently havent re-gased the system but i dont even use it)

has anyone had this sort of problems and what was the outcome?

pls help as i drive the car everyday . (but i have another car anywaiz) but i wanna get this fixed.

thanks pepolz

:)

probably the most effective way to determine it's location would be to remove each belt until you can isolate the noise. Start with the Power steer as it is in front. Then remove the Air con belt.

If the noise disappears after removing the aircon belt then it will be either the tensioner pulley or the air con pulley bearings. A way to tell between the two would be with a very long screw driver or long thin metal probe. Place the probe over the front nut of the tensioner and listen to the end. Put it right up to your ear. If it is louder than the compressor pulley then this is most likely your problem.

Another way would be to turn on your A/C. If you do isolate it and it turns out to be one of these two, tun the A/C on, with the belt on of course. If the noise disappears then usually it would be the compressor pulley. If it stays the same then it would be the tensioner.

Obviously it also depends on the noise that it is making. If it is a high squeel then it is more likely to be a belt. If it is a growly noise then pulley or bearing or pump.

If it sounds like a belt, spray a couple of very quick squirts of WD40 onto the ribbed side of the belt. (only a small amount - don't pile it on)

WARNING! Be very very careful when placing the probe onto the tensioner pulley nut. It can be very dangerous if you are not careful.

when i turn on the A/C the sound is still there but not as loud, im thinking that it would be the tensioner pulley...

i did spray abit of WD40 on the power steering pump pulley first and on the bottom pulley and the sound is still there ... but i havent sprayed on the belts..

i guess my only way around it is remove the belts and pit point where the noise is coming from as u mentioned.

though when i look at the tensioner pulley closely i can sort of see it wobble just a little bit .. but i reckon 80% it could be the pulley.

i also rang nissan parts in Rosehill and they gave me a quote on the genuine pulley price $150 is dat right? does anyone know where else i can buy cheaper or i have to go genuine?

thanks 3LIT3 FORS3 for your reply.

My car (1989) has belt noise for 30secs (ish) following cold startup.

I'll check out where the noise is coming from (thought it was the alternator - only because it goes away after startup). Thanks 3lite3, I'll try the WD40. Cheers

found the problem ...

i tried the wd40 / rpc stuff and didnt solve the problem .. so i cut off the aircond belt (my aircond doesnt work no gas and dont use it.) and found that the problem was the bottom "tensioner pulley".

so imma get that replaced but nissan genuine parts chargin me $120-150 ...is da price right?

thanks anywaiz guys .. "problem solved"

      Strange issue RB25DET wont start

      By jtha7 · Posted

      Ps i found the below forum and it seems to be the same scenario Im dealing with. Going to check my ECU coolant temp wire tomorrow    From NICOclub forum: s1 RB25det flooding at start up Thu Apr 11, 2013 7:23 am I am completely lost on this. Car ran perfectly fine when I parked it at the end of the year. I took the engine out and painted the engine bay, and put a fuel cell with an inline walbro 255 instead of the in tank unit I had last year. After reinstalling everything, the engine floods when the fuel pump primes. if i pull the fuel pump fuse it'll start, and as soon as I put the fuse back in it starts running ridiculously rich. I checked the tps voltage, and its fine. Cleaned the maf as it had some dust from sitting on a shelf all winter, fuel pressure is correct while running, but wont fire until there is less than 5psi in the lines. The fuel lines are run correctly. I have found a few threads with the same problem but no actual explanation of what fixed it, the threads just ended. Any help would be appreciated.

I found the problem though. There was a break in one of the ecu coolant temp sensor wires. Once it was repaired it fired right up with no problems. I would have never thought a non working coolant temp sensor would have caused such an issue.

      Hi sorry late reply I didnt get a chance to take any pics (my mechanics on the other side of the city) but the plugs were fouled from being too rich. I noticed the MAF wasn't genuine, so I replaced it with a genuine green label unit. I also swapped in a different ignitor, but the issue remains. I've narrowed it down a bit now: - If I unplug and reconnect the fuel lines and install fresh spark plugs, the car starts right up and runs perfectly. Took it around the block with no issues - As soon as I shut it off and try to restart, it won't start again - Fuel pressure while cranking is steady around 40 psi, injectors have good spray, return line is clear, and the FPR vacuum is working. It just seems like it's getting flooded after the first start I unplugged coolant sensors to see if its related to ECU flooding but that didnt make a difference. Im thinking its related to this because this issue only started happening after fixing coolant leaks and replacing the bottom part of the stock manifolds coolant pipe. My mechanic took off the inlet to get to get to do these repairs. My mechanics actually just an old mate who's retired now so ill be taking it to a different mechanic who i know has exp with RBs to see if they find anything. If you have any ideas please send em lll give it a try. Ive tried other things like swapping the injectors, fuel rail, different fuel pressure regs, different ignitor, spark plugs, comp test and MAF but the same issue persists.

      Freddy Plenum vs Genuine options RB25

      My return flow is custom and puts the return behind the reo, instead of at the bottom. All my core is in the air flow, rather than losing some of it up behind the reo. I realise that the core really acts more as a spiky heatsink than as a constant rate heat exchanger, and that therefore size is important.... but mine fits everything I needed and wanted without having to cut anything, and that's worth something too. And there won't be a hot patch of core up behind the reo after every hit, releasing heat back into the intake air.

      There is a really fun solution to this problem, buy a Haltech (or ECU of your choice) and put the MAF in the bin.  I'm assuming your going to want more power in future, so you'll need to get the ECU at some stage. I'd put the new MAF money towards the new ECU.
