Hey

I've done searches in regards to this, but there are differing opinions and not many proper answers...

I've dumped oil plenty of times. This time though, after letting the oil drain for about an hour, I went ahead and put in fresh oil. But I've accidently overfilled...

It's 4L engine + .4L oil filter on a RB20DET. Engine has done 150k.

I put about 4L in, let it sit, had a look at the dipstick and it showed above H. Went for a small drive, let it sit again, but still sitting about 4mm too high. The dipstick shows the oil level about 4mm above max. and it just touches the letter H.

Should I drain some out?

Cheers

Nah no dents, sump is all good. A fair bit of oil must have remained even after draining...

I think the best thing to do is simply get it at the correct level.

I'll see if I can drain some without undoing the plug completely, otherwise I'll dump the lot and then put it back in at the appropriate level.

Just to recap.

You come on here asking if the oil overfill is ok.

2 people say it is ok.

You somehow decide you should drain it.

Seems odd.

I don't know why you'd say that, I get asked for help all the time and it goes roughly like this:

*phone rings*

Me: "Hello"?

Caller: "Hi I need your help with X, it's doing Y"

Me: "I know what the problem is, you need to do Z"

Caller: "I don't think so, I reckon it's.............."

every. single. time.

I think people are just f*cking useless at asking for help.

To weigh in on the original conversation I fill between the H and the hump on an oil change (in an RB25 you can just dump 5L in if you have drained it on a level surface). I assume the hump is the danger zone much like there's a hump on the low side as well.

      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.

      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).
