Probably been covered before, but I'm interested to know....

What do your gauges sit at at cold start up? Then when normal temperature is reached what does it sit at? ie. idling in traffic?

Mine on cold startup sits just over 4 then when idling in traffic is just slightly over the 1st quarter on the gauge.

This could make an interesting little poll....

Ev.

RB26DETT here:

Sits on 4 ish when cold. When it heats up it sits on 2 ish. If drive it hard, with some full throttle etc, it drops right down to 1 or below.

As the oil heats up the pressure should drop. Changes will vary between oils, a low viscosity at hot oil (ie: 5w/30 or 10w/40) will have a lower pressure than a higher viscosity at hot oil (ie: 5w/50 or 10w/60). The second number refers to the oils hot temp weight.

I have found that it reads different depending on the oil level, if I have over filled it a bit, it reads higher than normal until hot, if its a bit under it reads just a bit lower, when hot as well. it reads alot higher for the same amount of less does.

Anyone think mine is too high?

R32 GTR, freshly built, n1 oil pump

cold 8 bar,

warmed up 4

driving hard between 3-4

Oil - Mobil 1... forget viscosity of it...something like 10-50 or 5-50..

About the same as mine.

When its cold, its just under 8 bar tho.

      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).
