Hey all my R34 seems to be having an issue with oil. Every time I service it I put in almost exactly 5 litres of oil but then after around 3000ks I usually have to put around another litre in, which I'm guessing isn't exactly normal. Also the oil pressure gauge gets gradually lower (as you'd probably expect) so I was wondering where the usual suspects for an oil leak would be? There is nothing underneath the car when I leave it for a week or so and there is no visible oil I'm the engine bay. This is just on the outside however I haven't had any time to pull anything apart I've been to busy.

To give a bit of additional info I'm using nulon synthetic oil and a genuine Nissan oil filter. Any help is appreciated cos I have a couple of days off now so I wanna find it if possible

If it's not leaking out you don't have a leak! It would be getting burnt. Keep topping it up and thrashing the car. Also stock nissan oil pressure gauges aren't accurate so I wouldn't care what it says, if you do care get a decent oil pressure gauge.

Would it really burn that much? It's only a daily driver which rarely sees more than 2 psi positive pressure... Most of it's life is spent on freeways. Just seems excessive

well the oil cant be just disappearing! if that was a leak you would see it easily. don't worry about it.

Unless you have had it from new then you dont know how previous owners have treated the engine, maybe its getting babied now but it couldve had its arse kicked/overheated/thrashed before you got it

    • By popular demand.. it was a coil. Got my hands on 1 new OEM coil, replaced with the one that made the less noise difference when I unplugged it while the car was running and started the car up. No stutter and the engine light was gone. I guess I’ll buy the other 5 they have lol
    • No, code 21 is very straightforward. It can only be the things described in that diagnostic flow. In fact it has no way of knowing that the spark plug resistance is out of spec.
    • 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
