good afternoon. today when i was under my car i noticed oil nicely spread out under my car. All down the tail- shaft all around on the floor of the car (outside) all the way to the diff.

Closer investigation tells me the oil may be coming from the back of the gear- box where the tail- shaft connects.

Any thoughts and help with this will be appreciated. :)

It sounds like the output shaft seal.

Double check to make sure it's not coming from the top of the box by removing the gearbox insulator and look at the area around the shifter dust boot.

Another point where it may come from is the breather, which will spill the oil over the top of the box as well.

If these areas are clean, then it's the output shaft seal.

I have oil leaking from the top of my gearbox. 2LV8ETR where is the breather located - is it on the passenger side or the drivers side (I am guessing it is on the passenger's side). If oil is coming from here is there a way to fix it?

When you talk about "the gearbox insulator and look at the area around the shifter dust boot" are you talking about looking around the shifter from inside the cabin?

Thanks, Ben.

It's on the starter motor side on top of the bell housing behing the inlet manifold - Or it should be.

Oil shouldn't be coming out of here. If it is, it's usually do to an overfill.

If you remove the shifter gaiter from the center console, you'll see a large square concertina rubber dust boot with a square metal surround. This is the insulator. It's actually in 3 parts, 2 rubber, and 1 steel.

Sorry to steal the thread (this may still help you). When I switched my transmission oil I had fluid come out of the breather at the top of the transmission, well I think its breathers, they are u-shaped and at the top of the transmission near where it connects to the engine. I filled the transmission though the filler hole underneath the car (not the shifter) and it still came out. It never really leaked too much on the ground as most of it just went all over the transmission. I have seen some gtr transmissions with hoses coming out of the u-shaped piece (90% sure they are breathers), so in that case the fluid would end up on the floor instead of the transmission. I also had a messed up shift boot which caused some fluid to leak. There is two shift boots, well actually 3, but two rubber ones. You first take off the shift knob in the car, then the leather shift boot, then you'll see a rubber boot with 4 screws, take that off, then you'll see another shift boot, that one tends to crack (from what I'm told). You can get it at any nissan dealer and its pretty cheap. If not PM me I have an extra.

    • Hi, i’m making a rb25det coil loom for Vag short coil. Can anybody tell me which Ecu signal wire belong to coil number 1 and 2,3,4,5,6? The connecting switch in above pic is 8 wire i think white is for +12v and black for earth.
    • Was there ever a model of the Stagea m35 that didnt have a badge on the grill? I thought I saw that somewhere, some aero edition or something? I cant find it again? davemoto
    • Its a 2002 vr-x four VQ25DET, silver. Coil overs, lowered, polished alloys and sport exhaust. Bit of a project, was sitting in a shed for a while but runs and drives great.
    • I wasn’t able to replicate the sound anymore. It was a one time sound so maybe it was just coincidence but it was like small pebbles being dropped in a coke can.   should I try cleaning the MAF? It could be it’s functioning but dirty? I don’t know.
    • Update 4: Hi all. The car drives again! Haven't driven for long, only to store it in the garage again, but the test drive was successful. The coolant and oil leaks seem to be fixed for now. Temps on the engine were also very good, while moving I never even saw 80C water during the approx. 30 minute drive. Ate up all the coolant in the reservoir though so will have to fill that even more when I go to the car next time. One thing that pisses me off is that the RPM gauge is still f**ked, I even resoldered the board twice and used copper paste on the silly screws that are used as connections. Next time I take it out I'll take apart the board and fit new components, I'll see if I can get a replacement IC for it.  I have an appointment set for 22nd of September for the engine tune to 370hp. Alignment also still needs to be done. My hope is that I can get all the legal stuff over with by the end of this season. Anyone of you have advice regarding intercoolers? Currently there is an APEXI core fitted, one of those weird hybrid ones, 600x270x76. I don't think it's bad but it's not new and now I still have the chance to change it now to legally include it in the paperwork. Only issue is that the only options that would arrive in time are a HKS Type R intercooler or generic Ebay spec intercoolers comparable to a JustJap one. Ideally I'd order a Plazmaman but it takes over a month to receive which would mean making the car legal has to wait until next season. Would love to hear some input on this. Same story for my injectors, the previous owner was a nunce and put ID 1050x on the engine. They work but are obviously not ideal at "normal" power levels. But I don't see a reason to change them unless the tuner says it's necessary. I read online before buying a different exhaust that the top secret style rear diffusers won't fit due to the size of the rear resonators. My buddy and I made it work by slightly "adjusting the shape" of the mounting bracket and making some spacers out of 3d print for the mounting bolts. Fits like a charm. Just putting this here in case someone has this problem. Even the hefty HKS Silent Hi Power rear can fits without hitting anything.
