Dayuum... has anyone tried this on an r33 yet? it's right under the inlet manifold! basically need to take the whole inlet off to even see it! this will be a bastage of a job...

Hence my tut and pics to show where it is. It took me forever to work out what it was based on people's description! haha

I dont think you need to take the whole inlet manifold off. I was trying to get to mine coz i have a high idle problem. If you take the oil filter off it will give you a bit more room.

I just did an oil and filter change so the air regulator is going to have to wait

yeah it's actually in a different spot again... the biggest thing for me was knowing what the damn thing looked like! but yeah descriptions alone just dont cut it! below that WHAT, exactly? :P

good work mate

Inasnt you're right removing the oil filter will free up a bit more room, still think it'll be a caaaaan't all the same. I'm in the same boat as you, just did the oil change. it's just a right piss off! the other day my damn car stalled because of it... and I hate hearing that pinging when it pulls itself back up off 100rpm! think i'm just gonna have to skin some knuckles...

This was an absolute pain in the ass to do, had to open up the air reg while inside the car coz the harness would just not come out. But I am so happy after checking AFM, throttle body, TPS, cleaning AAC this finally semi-fixed my idle.

It has however mostly fixed my idle, I'd like to know whether inside of it the opening is meant to be over the hole at all. In the picture posted it looks like there is still a slight gap(about 1mm), and that is the same with mine, however I would have thought it should be fully closed. The idle has dropped down now(but now its almost stalling coz it drops well under 500 after reving then flicks back up), but I wanna know whether i will need to buy another air regulator to adjust it all properly.

btw I couldn't find a spring to buy that was small enough anyway.

Cheers,

Adrian

I will be trying this tonight...Does anyone have any pics specific for R33?

I had a look last night to see if I could find it based on this thread, with no luck.

I might take the plenum off to make things easier.

I took mine out and gave it a clean however I noticed that the spring was not holding the bimetallic plate on fully, allowing air to escape on idle (causing idle to stay around 1500-2000 depending on temp)

I got a quote from Nissan, $276.95 for a new valve. I will give this a go and report back. Hopefully the idle will drop back down to normal.

For an R32 RB20 you don't need to remove half the stuff listed. I just pulled off one side of the 2 small vacuum lines and the larger lines with the T-piece. The only tricky bit is working around the loom which runs over the top over the unit. Oh and dropping the bolts down into the manifold :).

Hence me saying...

"2) Have a look, and work out if you can get to it as is. I couldn’t; so I chose to remove the following, you can skip ahead if you think you can get to it without removing them."

      Leak from Tokico BM50 Brake Master Cylinder

      By brillo · Posted

      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.

      R33 GTST Steering Rack (49001-19U05) Rebuild?

      By Gantai · Posted

      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

      Leak from Tokico BM50 Brake Master Cylinder

      By SteveL · Posted

      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).
