My gearbox crunches going into 2 and 3 when cold especially, and sometimes when going into 4-5.

Its goin in for water pump/timing belt/gbox oil 2morrrow, should i use redline mt90 or lightweight shockproof?

OR should i listen to hills and use that new fusch(spelling..) stuff?

I would generally take their advice, but i get the feeling they are making more $$ on fusch than other oils which is why they push it so much, and after seeing the inside of their custom plenum, im not sure whether to trust what they say anymore...

True

Ill be doing the change 2morrow if i can get the nuts(!!) off.. I spoke to rick shaw performance and te guy rekcons for 33s like mine redline yellow(ultra lightweight) is the way to go.

I was gonna get it done at hills yesterday along with the water pump and timing belt, but they stuffed me around and dont actually have it in stock.

On friday i changed gearbox oil in both a z32TT and my car with a friend. A tip for people...i was gonna write a guide on doing it but didnt have a digital camera with me.

Do not try and undo the top bung! Its impossible!!! we broke a ratchet spanner doing it!

instead, undo the speedo sender, pull it out and a nice big hole will be available.

Apparently the redline oil takes at least 500km to wear in. I have driven 250km, and this morning when the car was cold, crunching into 2nd and 3rd had completely gone. Even when i rushed a change. So yeah id recommend the redline oil.

J - DO NOT use the ultra lightweight. when it gets hot it expands and bleeds out of the breather :stupid: i rekon ive lost about 500mL and the bottom of my gearbox is covered in this yellow shitty oil. Im changing to Castrol Syntrax 70/85 synthetic next weekend - see how that goes.

Just had a thought...maybe you overfilled and this makes the bleeding problem worse..cuz its only meant to have 2.8L But will accept more. I put in about 3.3L and it still wasnt coming back out of the hole..

thats shit. Hope it magically doesnt happen to me. A friend was telling me something that may contribute to this expanding problem... He saw a test on lucas additives(favoured by a few workshops...) where when gears were spun slowly the lucas enhanced stuff stuck to the gears well, but when they were sped up, the lucas stuff bubbled ad frothed....causing extra heat..expansion...stuff like that which im sure would lead to issues like yours.

So yeah do u have additives in the oil?

I guess ill have to take the car for a hard drive to find out if it happens to me.

i almost put in 4 litres and was suprised when only 3 litres come out before i filled it up.

are u sure about this?

    • I mean, I got two VASS engineers to refuse to cert my own coilovers stating those very laws. Appendix B makes it pretty clear what it considers 'Variable Suspension' to be. In my lived experience they can't certify something that isn't actually in the list as something that requires certification. In the VASS engineering checklist they have to complete (LS3/NCOP11) and sign on there is nothing there. All the references inside NCOP11 state that if it's variable by the driver that height needs to maintain 100mm while the car is in motion. It states the car is lowered lowering blocks and other types of things are acceptable. Dialling out a shock is about as 'user adjustable' as changing any other suspension component lol. I wanted to have it signed off to dissuade HWP and RWC testers to state the suspension is legal to avoid having this discussion with them. The real problem is that Police and RWC/Pink/Blue slip people will say it needs engineering, and the engineers will state it doesn't need engineering. It is hugely irritating when aforementioned people get all "i know the rules mate feck off" when they don't, and the actual engineers are pleasant as all hell and do know the rules. Cars failing RWC for things that aren't listed in the RWC requirements is another thing here entirely!
    • I don't. I mean, mine's not a GTR, but it is a 32 with a lot of GTR stuff on it. But regardless, I typically buy from local suppliers. Getting stuff from Japan is seldom worth the pain. Buying from RHDJapan usually ends up in the final total of your basket being about double what you thought it would be, after all the bullshit fees and such are added on.
    • The hydrocarbon component of E10 can be shittier, and is in fact, shittier, than that used in normal 91RON fuel. That's because the octane boost provided by the ethanol allows them to use stuff that doesn't make the grade without the help. The 1c/L saving typically available on E10 is going to be massively overridden by the increased consumption caused by the ethanol and the crappier HC (ie the HCs will be less dense, meaning that there will definitely be less energy per unit volume than for more dense HCs). That is one of the reasons why P98 will return better fuel consumption than 91 does, even with the ignition timing completely fixed. There is more energy per unit volume because the HCs used in 98 are higher density than in the lawnmower fuel.
    • No, I'd suggest that that is the checklist for pneumatic/hydraulic adjustable systems. I would say, based on my years of reading and complying with Australian Standards and similar regulations, that the narrow interpretation of Clause 3.2 b would be the preferred/expected/intended one, by the author, and those using the standard. Wishful thinking need not apply.
    • Yes they do. For some maybe. But for those used the most by abusers, ie Skylines, the numbers are known. The stock eyebrow height for R32/3 Skylines is about 365/375mm or thereabouts. The minimum such heights are recorded in adjacent columns in the database.
