hey guys iv got a small oil leak in my rb20det, it appears to be coming from the turbo side at the back, heres a pic;

the area i have circled is the highest point that oil appears to have built up, it then runs down the side, there is also some oil built up behind the engine(where the arrow points)

can anyone help me determine where this leak could possibly be and if so how i would go about fixing it?

ive got the exact same leak too on my 33. had the gasket replaced by one workshop but there was still signs of leakage. had it double checked cleaned and tightened again by another workshop but it came back. my suspicions are its the oil line that goes into the block directly under and when there's air turbulence in the bay(ie driving) it throws the oil around. I can see the nice pool of oil down below infront of your gbox, mine looks exactly the same. I have yet to properly double check my hunch with a mech so i dunno but when i had it up on the hoist for a quick road worthy the guy came to the same conclusion.

are you referring to the oil line that runs from the block to the turbo? i replaced my gasket this morning and so far so good but ill keep an eye on it over the next few weeks.

I have a similar problem. Except mine is towards the front of the engine. It doesn't seem to effect the performance of tje car at all and the oil pressure doesn't appear out of the ordinary. I'll check the rocker gasket and see. Hopefully that's all it is.

    • Reasonably hard, although I haven't run it with the new Endless setup yet. The old brakes were F50's on 335mm rotors and the car did a 1:40.6 at Phillip Island which is a reasonable time, I'm seeing high 600s on the temperature paint. A guy I know ran the Endless fluid at WTAC without issues and he was doing 1:33's I think (Evo) with a 355/332 setup. I don't get out to the track as much as I'd like but we put the car on the hoist and spanner check every bolt and re-paint mark everything, bleed the brakes, change the fuel, check the coolant system and re-bleed blah blah blah before every event. Motorsport is expensive, RB's are expensive so a couple of hours before an event is time well spent. It's also a net time saving because if you can keep your RB from self destructing it saves you time in the long term!
    • Welcome Alice......hope you have a bit more luck from here on! What was done in the build?  
    • Hello! I'm new here, I have an R33 GTST that is currently being finished up! Last year was pretty rough, blew two stock turbos so I decided to build the car. Has been down since November, but I get it back next weekend!
    • Hello, I believe my car was imported to America in the 2000s by Kaizo Industries. Would anyone be able to help me find more info on them? I've only found all the basic stuff like that paul walker bnr34, them being shutdown by feds, just stuff like that. Any help would be much appreciated, thanks!
    • I am using Motec M150.  I am not working on the car myself actually.  My workshop is giving all these info, they are quite reputable in the industry and are very familiar with Motec and RBs and have done a few big setups with VCam and single turbo on RBs.  In fact, they built and tuned my engine from day one.  But they are stumped with my engine at the moment and cannot work out how come the compression is so low with the VCam. They told me that they have now swapped in some Kelford cams (without the VCam) and can achieve around 130psi compression and the low end torque is better, but now the engine is doughy as.  It boosts and peaks at more than 1000rpm slower, with twin HKS GTIII RS, it doesn't get full boost until over 5000rpm. I have always thought the VCam was a bit disappointing at the low rpm. To a point I had to ride the clutch a fair bit to get up a small hill from stand still.  That was when I had a clutch.  Now changing to a 8HP, I don't have that luxury and this problem has become a major issue. I am beginning to think the VCam never work since the day it was installed.  Maybe it was just sitting at the most advanced point, that is why it went good at top end but very ordinary at the bottom.  Therefore, with the help of the Holinger 6 speed and paddle shift, as long as it was moving, it drove pretty good.
