Engine Noise On R33

Recently my engine developed this annoying rattle at 1500rpm or so. It seems to disappear once the revs climb, and it doesn't do it at idle, only in the 1500-2000 rev range. Any idea what this could be? It sounds like it's coming from the front of the motor, but i'm not sure if it's from the top or from the pulleys and belts at the base.

I believe that this is your timing belt idler or tensioner pulley bearings starting to show their age. My car had this exact noise in the same rev range and when I replaced the timing belt and pulleys, the noise was gone. If your car is coming up to 100 000 km then I would get them replaced pronto.

Mine's only supposedly done 56,000km but. How would i check if it is the timing belt?

I got my mechanic friend to do the replacement for me, but I think the best way to check the belt is to get a mechanic to take off the cam gear cover and crank angle sensor unit to inspect the belt condition. I think in my case it was more to do with the bearings in the 2 pulleys as they sounded like a cement mixer when you spun them.

It isn't a cheap exercise to replace all these components, especially when you have labour costs to consider, so I would probably get a mechanic to check it for you to be honest. This way you won't end up replacing something that might not be broken.

I think the parts cost me about $500 and there will be a few hours labour involved. My car had come up to 100000km when I bought it so I had already factored this into the equation. My car is a 95 r33 so I think it's around the same age as yours, going from your sig.

If you can get your hands on a stetescope. (kinda what docs use to listen) you'll be able to pin point the noise. Approx $15 from Autobarn... supercheap... repco ect. I've got a similar noise to what your saying and i found it's my A/C compressor bearing. It only does it between 1,500 and 2,000 RPM. It's annoying but i'd rather wait till it gets worse and buy a new one, my A/C still works fine!

Or another poss. maybe check the tension on all your belts and timing belt.

Hi I bought my skyline about 2 weeks ago and I'm still getting used to it but I've noticed sometimes when I'm shifting up from 2nd to 3rd that theres a coarse gravely noise until i get to around about 40km/h and then things start smoothing out. I haven't noticed what rev range it occurs in. Is this normal?? or I am shifting up to early (I think it should be)?? My last car was an auto and I haven't driven manual in about 2 years?

Cheers,

AF

Could be the springs on your spung centre clutch are loose...

Mine made a grinding noise b/c of a faulty clutch plate where the springs were loose. It always did it at lower revs, and most audiable in 3rd and 2nd gears.

If I changed gears to early and load it up at 1,500 rpm in 2nd or 3rd, it was very noticable...

Damn I think you hit that right on the bulls eye...I'm guessing thats going to be a fair bill to fix.

that means the clutch plate is faulty (sort of).

From what I understand, if it IS that, then it won't cause any damage, it is just an annoyance.

Cost to fix is basically replace clutch plate...

What clutch do you have?

I have a daiken exceedy organic sports clutch.

I'm not too sure, hey? I just bought it probably just on two weeks ago now but there was no paperwork (manuals, instructions or compliance or whatever else)with it, even though I bought it at a dealer...come to think of it, I think the bastard's ripped me off since now the front right small headlight thing (the corner one, the faint ones?!) doesn't work anymore..

do you by any chance happen to know where a good reliable skyline service centre is in Syndey or where I can get keys, manuals and stuff from?

      Jacks that fit under GTR lips that can reach the subframe?

      You know how your car rolled through a fence in your last jacking escapade? Scissor jacks increase the likely hood of that sort of thing happening immensely!

      http://calfinn.com.au/product/1500kg-standard-trolley-jack-cj-2t-c/1500kg-standard-trolley-jack-cj-2t-c   I have this and fits under a S3 33 GTR with no issues. Purchased in 2009 and not one issue. It was $950 back then. Not cheap but something so important isn’t worth cheaping out on.

      Just trying to get my head around this. At 5psi of boost, you turn on your wmi pump, and then you're using a 3000cc injector, to allow flow upto the actual engine, where you have your 6x200cc injectors and a 500cc injector. If the above is correct, what advantage are you obtaining by having the 3000cc injector blocking flow, is this just incase a line breaks between that injector and the motor you can stop flow immediately? Or are the 6x200cc and 500cc less injectors and just spray nozzle?

      Intro/R33 owner

      By f00stx · Posted

      Welcome! New member myself, but I had an R33 back in 2002. Best advice I could give, based on my experience: if you're running the factory turbo, be very conservative with boost. I made the mistake of just fiddling around with the boost controller and cranking the boost for fun, and the end result was my intake pipes popping off frequently from the constant deluge of oil that was being blown into the recirc by the stressed-out turbo, which itself was siphoning oil from the engine and farting it out both sides of its centre bearing (or something to that effect). If I could do it all again, I would have gotten a new turbo and had a tune dialled in professionally and then just left it alone! Funny you mention the metal shavings in the gearbox, as I had the same thing - the probe plug (magnetic drain plug, essentially) would come out caked with shavings. At least it was doing its job. Not sure if that's just sacrificial wear and part of the deal, or if my gearbox was shagged, but I wasn't abusing it. Enjoy the R33 - they're a dying breed, and if they weren't $35k+ on CarSales in Queensland, I might have picked up one of those again, instead of the 370GT I own now (though I'm loving the 370GT, that big 3.7L V6 just hits different).

      Second time Skyline owner (R33 GTS-T and now a V36 370GT)

      Howdy folks. I owned an R33 back in 2002, which was thoroughly beyond my capacity (financially speaking) to maintain/insure, so we parted ways in 2004. Fast forward 21 years (to literally yesterday, in fact) and I'm now the proud owner of a 2007 V36 370GT. I'm happily surprised by how much power the VQ37VHR makes, compared to the RB25DET, considering the latter is turbocharged. I had planned to add a turbo at some point but I'm on the fence about whether I'll even need it (though I do love the sudden onset of extra torque). Any other 370GT owners around the traps, I'd love to hear about your experiences with this car (good and bad).
