low down is, i got car serviced on fri morn, it seemed perfectly fine, with the report saying all it needed now was a front end allignment etc...

got home from drive ins last night, put car into PARK tunred stereo off, and i could hear a fairly loudish whistling/whining noise from under the hood..as soon as i turned her off it stopped, but turned her back on and it came back again after about 5 secs..(the temp gause is always norm, i am sure of this cause i am paranoid about temp from a previous bad experince)

just took her for a burn around the block a few times at norm temp, and came back no noise at all apart from nomral, however when i switch the key off I THINK!! i heard a little slightest squel if you wanna call it but cant be sure

anyone know what this could be please..... i have to drive to adelaide tomorrow morn(moday)

i attach a pic of something that i thought was wierd but not sure if thats the way it should be or not(the little slits/holes between the pipes)

hmmmm i dont know what to do, wether to still go to adelaide or not, either way if i do i think ishould get racv total care so if i do die on the way up there, i can at least get a free tow all the way back home from anywhere in aus, and get a hire car for therest of journey hehehe....this sucks, always something happens either when you have to rely on the car or you have had a good night(ie the meet) then get home and something like this freaks you out)

it sounds like the belts, check the tightness if the belts if they are hard as a rock or loose when pushing them down, thats your problem and you'll need take it back to where you did the service and loosen them or tighten them accordingly.

yep i had a similiar problem on my silvia and it turned out to be power steering pump, it was hard to figure out what it was too!

My mechanic told me that if i drove it too long like that the pump might seize or something and damage other parts ending up in a big bill$$$...

So check your steering pump, if its not that then maybe waterpump?

A couple of possabilitys here:

1. Does it sound like Air squealing out? (rubber hose?) vacum type sound?

2. Or more of a rubber on metal sqealch?

if it sounds like no 1;

Check all your intake rubbers & seals, make sure all clips are tight. (keep in mind that this leak might not be noticable, but under presure or vacume it might open, a split or pinhole in a rubber seal somewere, or even pipping .)

After you have checked everything under the hood, it might pay to take your front bar off and check your intcooler and intercooler piping. If you car is running higher than factory boost, it could be possable that there is a slight "stress" fracture in your cooler or some of the pipping. basicly check everything air travells through.

If it sounds like number 2;

Go down to repco, or somthing and buy some CRC Belt-Grip and spray it on all your belts (Not too much otherwise it will make a whining/supercharger sound). this will establish weather it is infact a worn belt or, a worn part that the belt runs. eg powersteering, ac etc. if it still makes a whining sound, its then a process of elimination: look for worn components under the bonnet. eg leaky power steering?, is there a way that oil can leak onto a belt? Does it still make the noise with your A/C on & off??

Also it might pay to check your timing belt. ( DONT SPRAY THIS BELT WITH BELT SPRAY!! =)

Good luck & Hope this helps.

    • Hi...so a "development" here aswell The swap is "done" and car went "test drive" BUT it seems the clutch(maybe gearbox?) is a little bit sad? I bought this clutch kit https://justjap.com/products/xtreme-heavy-duty-organic-clutch-flywheel-kit-nissan-skyline-r31-r32-r33-push-type "Problem" is that the first gear is hard to put into and it seems that the clutch is not disengaged. It was not the problem with the old clutch...(or like sometime the first gear would not get as easy specialy when the fluid was cold) So? Can it be like...bad "install" or is the clutch wrong ((it should not have been) i done research to get the right one) Or is this "normal" with new clutch and needs to be break in? 
    • @Duncan I can try  and thanks i did not thought about VIN and part numbers for 33/34. @GTSBoy yeah it looks like iam gonna do that  
    • Forgot to include this but this is the mid section of my steering rack that looks like it has a thread/can be turned with that notch mentioned in the post:
    • Hey everyone, Wanted to pick some brains about this issue I'm having with rebuilding my 33 rack (PN is 49001-19U05). All of the tutorials/videos I've seen online are either R34 or S Chassis racks which seem to be pretty straightforward to disassemble but this process doesnt carry over to my rack. Few of the key differences that I've noted The pinion shaft on the other racks bolt on with 3 torx bolts: Whereas my rack bolts on with 2 allen head bolts: These changes are pretty inconsequential but the main difference is how you pull the actual rack out of the housing. The other skyline/s chassis racks can be taken out by tapping the rack out of the body with a socket and it just slides right out. I'm unable to do that with my rack because there's a hard stop at the end that doesn't let the seal/shaft be tapped out. Can also see a difference in the other end of the rack where mine has a notch that looks like you're able to use a big wrench to unthread 2 halves of the rack whereas the other racks are just kinda set in with a punch. My rack: Other racks: TLDR; Wanted to know if anyone has rebuilt this specific model of steering rack for the R33 and if there were any steps to getting it done easier or if I should just give this to a professional to get done. Sorry if this post is a bit messy, first one I've done.
    • I would just put EBC back on the "I would not use their stuff" pile and move on.
