Anyone now someone who is missing a Black 180sx reg S843AVM....

It is parked outside my place and looks like it has been tampered with and dumped...

SAPOL said it has not been reported stolen but from everything I can see it looks like it has been.

need a lil help guys, was driving the gtr just cruising at 60 changed gears nice n slow n I felt a funny twitch in the clutch pedal and then next time I pushed the clutch is was a lot heavier all of sudden.

pulled over check the fluid levels all looks ok, then I noticed when I got back in it every time I pushed the clutch it was making a noise like gas escaping. This was in the car not under the bonnet.

so I hear this is possibly a vacuum leak in the booster? anyone got any other ideas?

anyways I drove it home and it felt fine aside from the weird noise and being heavier clutch than normal, went into gear fine no crunch.

What im wondering is, is this doing any damage to the clutch? I have the nismo coppermix twinplate so I don’t wanna stuff it up but its normally light as a feather and id actually prefer a heavier clutch pedal.

o and this car is starting to p me off

finally got it into a workshop and there tellling me its the thrust bearing is worn out and itll cost 550 in labour to rip the gbox out to replace it. they are suggesting i wait till the clutch is worn to replace it.

ive got no idea what the thurstbearing is, will it damage the clutch or make it wear out faster? it seems to feel alright other than the noise at the moment.

anyone know how much it is to rebuild a nismo twin plate anyways :P

I'd just leave it for the moment but $550 seems a bit too pricey for that type of work, it's a little brass "ring" worth about $3 from Nissan.

To rebuild a Nismo twin plate is about $900ish from NPC

Luke i think your thinking of the spigot bearing that sits in the end of the crank and the end of the input shaft runs inside it.

The thrust bearing is on the bearing that rides on you input shaft and it what pushes (or in the case of a pull type clutch, pull) the "fingers" on the clutch when you press your pedal.

Regardless both parts are worth bugger all but it is a gearbox out job so would there's a fair bit of labour involved.

I would take the mechanics recomendation and wait until your clutch is stuffed and do them together becasue the labour cost will be the same.

It won't damage anything but if you end up with a scretching noise when you press the pedal then the bearing has colapsed and you will then need to change it.

Having said that the symptoms that you have described don't sound like thrust bearing to me as that would have no effect on pedal feel.

Your thoughts about the clutch booster sound more on the money to me. The other thing it could be is a broken pivot point for your clutch leaver. I have had the same thing happen to my car and after month of not figuring out what it was eventualy (on an SAU cruise) i put my foot and the pedal and the clutch didn't engage which led an emergency pit stop at windies lookout. Ended up driving the car through the hills back to Campbelltown with no clutch which was a lesson in matching revs on gear change.

if its not a daily driver ya could tear it apart, find the problem, fix/replace the part and whack it back together yourself.

it would be an educational experiance and you could get to know your car a little more in doing so, it would make for a fun and intresting weekend.

FYI my brother-in-law David (Red back on SAU) is running his R33GTR (with R34GTR Nur engine in it) at the Bathurst Motorsport Festival this weekend. FB group below if anyone want to check out pics/join.

    • Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.  
    • Well the install is officially done. Filled with fluid and bled it today, but didn't get a chance to take it on a test drive. I'll throw some final pics of the lines and whatnot but you can definitely install a DMAX rack in an R33 with pretty minor mods. I think the only other thing I had to do that isn't documented here is grind a bit of the larger banjo fitting to get it to clear since the banjos are grouped much tighter on the DMAX rack. Also the dust boots from a R33 do not fit either fyi, so if you end up doing this install for whatever reason you'll need to grab those too. One caveat with buying the S15 dust boots however is that the clamps are too small to fit on the R33 inner tie rod since they're much thicker so keep the old clamps around. The boots also twist a bit when adjusting toe but it's not a big deal. No issues or leaks so far, steering feels good and it looks like there's a bit more lock now than I had before. Getting an alignment on Saturday so I'll see how it feels then but seems like it'll be good to go       
    • I don't get in here much anymore but I can help you with this.   The hole is a vent (air relief) for the brake proportioning valve, which is built into the master cylinder.    The bad news is that if brake fluid is leaking from that hole then it's getting past the proportioning valve seals.   The really bad news is that no spare parts are available for the proportioning valve either from Nissan or after market.     It's a bit of a PITA getting the proportioning valve out of the master cylinder body anyway but, fortunately, leaks from that area are rare in my experience. BTW, if those are copper (as such) brake lines you should get rid of them.    Bundy (steel) tube is a far better choice (and legal  in Australia - if that's where you are).
