MY Kaaz sounds like its tearing itself to pieces!

Its was making BAd noises from the begining, as soon as i reversed out of the shed and turned it was doing it... i had to drive around 15k to get to a car park to run it in, but i drove sensibly...

when u go round a corner with the clutch in it makes a bit of a whiring noise.. that i expect.. but as soon as u are driving normally it doesnt sound happy at all....

(sounds like the thing is skipping splines on the axel... and no its not.. i checked.. twice)

if you have put redline diff oil in then this could be your problem, the oil is too thin for the kaaz diff and results it becoming very noisy; when did it start making the noises?

Ive got a kaaz 1.5 way with about 1500kms on it, and im not happy with the clunks and grinding noises either. Im thinking of pulling it out and putting a standard one back in. I changed the oil after run in with more kaaz oil, and the diff became a bit quieter, but still feels as though the rear cradle is dragging on the road when in car parks. I f**kin hate it at the moment.

I changed the oil in mine yesterday and put some Penrite Competition diff oil 140w in it and it is ten times better! still makes afew noises but nothing like it was!

So did you have the recommended Kaaz oil in it before you changed to the Penrite?

Ive heard that the Penrite seems to quieten them down a bit. When you say "a few noises", do you mean clunk!, clunk! around tight corners in car parks, or just slight grinding noises.

Thanks,

Shaun.

Toughen up people!

If you wanted a quiet diff you should have stuck with a viscous LSD.

I have changed the oil in my KAAZ diff twice, both times using KAAZ oil, each time it has quietened down a little. I am due for a third and final oil change, which will be done shortly, using a Castrol oil, which has been recommended by a friend using the same diff.

All mechanical diffs will be noisy as you accelerate gently through a corner, if you don't like the feel/noise just push the clutch to eliminate the drive force to the diff. I just don't worry about it.

REALLY bad clunkingnear on grinding noises.... One of a mates has a Kaaz and its quiet compared to mine.. mine sounded like it was tearing itself to bits!!

now with the penrite it just makes a few noises in carparks etc.. that i can live with.. very happy now!

Mate it doesnt worry me a f**k if it makes a few noises.. but this wasnt right at all.. it made more noises than a auto locker... now with the new oil its spot on!

I wouldnt recomend the castrol oil, ive got a nizmo 2 way and had the castrol stuff in there, wasnt to bad but later on i changed to penrite 90 weight stuff and it it heaps smoother, still clunks and stuff but i dont mind that :P

might be different to the kaaz ones, seems like you guys are all using a much heavier oil

2way LSDs are very aggressive and thanks to that will always make a noise and theres almost no way of drowning the sound completely but at least when your cornering you tend to forget about the noise. tho, i gotta admit the noise is annoying.

from what i heard from some, the nismo 2 way and the tomei technical trax 2way are quieter than the rest.

these diffs are supposed to make noise it feels like the whole cradle is moving and ready to drop out but if you don't want the noise then get a stock car i'm pretty sure all of these things ultimately have the race track in mind and that's where they are supposed to be used hence the lack of quietness if ya don't like it stock is the way to go mine sounds like crap but if ya want it you put up with it still works a treat oh and i use motul oil essentially the same as nismo oil just without the nismo and price tag

      Ticking Sound On Idle - Rb25

      Have you put an aftermarket oil pressure gauge on and verified your oil pressure?   Noise being on the block, on exhaust side, how high up the block does it seem to be? It could be the VCT system getting cranky, especially if it's mainly at idle, and when warm, as that'll be your lowest point for oil pressure. Could be showing that oil passages / VCT solenoid are blocking.

      Well, hydraulic lifters will get noisy if they are dirty/fouled in some way, and exactly how that manifests will depend on exactly what schmutz is where. There is a procedure on here somewhere for dismantling and soaking/cleaning them. Replacing them with new is about 50% of the work and about 5% of the money!

      Ticking Sound On Idle - Rb25

      By myrbgivesmeheadaches · Posted

      Thanks for the reply @GTSBoy this is is a hydraulic lifter engine. Yea right i did not realise the lifters were supposed to be compressible while installed. I could push them down but i had to lean almost my while body weight on them.  I have never heard of a lifter/ lifters ticking only at hot idle and getting worse the hotter it gets. I have owned a few jdm cars with noisy lifters. This noise is slightly more subtle, it is more of a sharp gentle metalic tic than the solid and more loud tapping I've heard on lifters. I have used a metal rod, alloy tube, hose and stethoscope and could not find the source of the tick. But it appears to be loudest on the actual engine block behind the exhaust cam gear and next to the oil filter. I had mate (40 year old mechanic) go over it with me and he couldn't find it either..  Could it be a cam seal issue of some sort?  Cheers

      This seems problematic and unlikely at the same time. Vanilla RB2Xs have hydraulic lifters. They do have "zero" clearance, but only when running with oil pressure inside them. When not running, you should be able to compress them and obtain heaps of clearance. RB26s and Neos have solid lifters. They should have ~0.3mm and ~0.5mm on the inlet and exhaust respectively. If they have zero clearance then bad things are happening. With nothing else being wrong, it would mean that the valves would be held slightly (ever so slightly) open when they are supposed to be closed and it should have all sorts of problems when running, caused by leakage in/out through the valves. Or, zero clearance can indicate severe valve seat recession. None of it is good. Have you used a piece of hose as a stethoscope to try to localise the noise?
