R34 Gt-T Oil Leak?

[RBrennan25]

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

Also the pressure seems to be around 1-1.5kg/cm2 when warm at idle and when around 3000rpm it's around 3.5

Is that normal or a bit low?

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.

What viscosity oil are you using?

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

What oil are you running?

[RBrennan25]

Nulon synthetic 10w 40 for winter. I'm gunna change to a a thicker oil in a couple of weeks now it's warming up

Turbo could be burning the oil. Any smoke out the back?

Just the standard ecu richness so far as I can tell. Certainly not over the top
