Ok so my car has been using quite a bit of oil recently... checked under the car a few times and it doesn't seem to be leaking...

there is quite a few black spray marks on my rear bar when I wash my car... this builds up in the space of a week... could it just be oil blowing through the turbo and out the exhaust...

I have had to put in 2 litres so far and the oil was changed only 4,000kms ago...

The oil pressure also seems to be sluggish...

Any ideas before I take it to the garage...?

If you can smell it then it might be leaking onto your exhaust then burning away, thus no visible drips.

Get someone to drive it away from you with a bit of stick and watch for blue smoke out your tailpipe to see if it's burning it.

For 1/2 liter/1000ks you're most likely not gonna get any tell tale signs. When a car starts blowing blue smoke due to shot rings you'll be using alot more oil than that. If your car smokes as soon as u start it, valve stem seals are gone. Otherwise your turbo seals could be on their way out aswell.

What oil are you using? You could use a thicker oil like Mobil 1 5W-50 to slow the consumption, and it'll have no ill effects.

thanks for your input guys... no blue smoke on start up or revving hard etc...

I think I just was using oil that was too thin cos I put some heavier oil in 10-50w and the pressure is back to normal... but time will tell...

I don't think the engine has had a hard enough life to have farked the rings or valve seals well have to wait and see... checked the odometer last night and I've really only got about 750kms or so to go before I should get a service so once the oil has been changed I'm going only going to top up with the same oil... (which is Motul something or other whatever the guys at ice use)

      I've heard the Tomei USA head gaskets are decent if you want to o-ring the heads but otherwise not recommended.

      What brakes on R34 GTT(Europe)

      By GTSBoy · Posted

      The 296mm rotors are the R33 turbo brakes. The 310mm rotors are the R34 turbo brakes. The calipers are nearly the same, but not. They're the same caliper but the R34 caliper has longer legs so that it sits out far enough to go over the rotor. The pads are the same for both. When you say, "I bough tsome EBC"....did you just mean pads? Or rotors? 310mm rotors fit under 17" wheels. There may be some wheels without enough clearance though. I can't fit my fingers between the barrel of my wheel and the "corners" of my R34 calipers, but there is plenty of room behind the spokes. This is on Enkei RPF1. You can fit 324mm rotors inside a 17" wheel, but I'd be willing to bet that it would be close to impossible with the Nissan/Sumitomo caliper (using an adapter, of course), because the Sumitomo caliper is fatter than the Brembo caliper that is supposed to go on the 324mm rotors.

      Hi. Can someone tell me what brakes(and mainly WHERE) can i buy brakes on R34 GTT? I bought some EBC which SHOULD go on my car(i have GT but it has GTT brakes) but it does not fit, Brakes are "too" small(296mm) Are 310mm be good or? I have 17 inch wheel so no "big boys" but for me driving i just need one that fits and i can get here in EU/Czech.

      Hey. Very valuable information about pitwork, I will pay attention when buying any consumable parts 🙏 As for the carpets - I got a handful of information from nengun, from which it appears that indeed the carpets for the driver's side are OEM. They are not able to show me any pictures due to the long chain of different sales entities but after I place the order, as soon as the goods arrive at the nengun warehouse from which they will send the shipment to me they can send me photos and if my purchase differs from OEM I can immediately return it / cancel the purchase. I think I will give it a try 😉. Of course i'll let you know what's what as soon as i get them P.s. I know the topic is not relevant to the thread, but both nengun and amayama have these SICK 😍 trunk room lamps available. Do you know anyone who ordered them? I need to have one in my car
