Hey all, got under my car today to look at my clutch slave and remove front bar, noticed this oily leak around where the gearbox attaches at the front, anyone able to give me a hand identifying what this might be? Could this be the rear main seal I've heard so much about? Thanks.

I haven't noticed any fluids going down, no. My power steering has a small leak but that's leaking from the reservoir, plus this doesn't look like power steering fluid. It seems to have the consistancy and colour of engine oil.

it looks rear main seal. i had a same prob. not a big deal mate. but fix it asa u can dont use crappy stop leak stuff.

could also be the engine sump gasket weeping blowing back check around the meeting point between sump pan and block if not id be the rear main

it's not coming from the rocker cover gaskets? have a look further up the engine block and see if there is oil up there. mine had a similar problem and it was simply the leaking rocker cover gaskets and because i parked on a steep driveway the oil was coming out and running down the back of the engine.

good point mate. 75% possible. chk that as well

Check to see if your have a leak from your sump as it can run down and drip of from the front of the gearbox, basically try and find the highest point from where the oil is coming from.

If not then it looks to be a rear main. Its not really a problem unless it leaks onto your clutch or if the seal lets go completly and dumps a crap load of oil everywhere and potentially stuff the motor.

Hey all, thanks for the replies. It's not the rocker cover gasket, that's been changed since I"ve had it and all is still clean around there. It's definately got the look/feel of engine oil so yeah.

Might need a new clutch sometime in the next 12 months so I might leave it until then, and get it done at the same time... i should just keep monitoring my engine oil level in the meantime yeah?

    • Nope.    Grab a varex and turn it down as you get close to home, win win? 
    • So, I've had my V36 for about a month now and have already copped an "excessive exhaust noise" notification from QLD TMR, reported by someone in my local area. It's a twin as per the original, and can have a bit of a throaty note to it when idling cold 😄 and if I do get up it a bit, it can be noisy, but it did pass a roadworthy inspection before sale, so.... ... but in the interest of being a good neighbour, I do want to quieten it down a bit. Is anyone here running a quiet aftermarket cat-back on their V36 or 370Z? And the big, bold question: does an aftermarket cat-back really make much of a performance difference on these cars?
    • The wiring diagram for the R33 RB25 is freely available, and is essentially the same same as most other RBs (just with differences as to which pin # does which job). To get the ECU to power up, you just need to provide power to the ECCS relay, and have the other power feeds that come in from the top left of the wiring diagram (wrt the ECU) that give perma power to the fuel pump relay, the ECU itself, etc etc, all connected. When you put power on all these it will just come to life. It's pretty clear from the diagram what needs to happen. Just follow the lines from the 12V + supply stuff in the top left over towards the ECU. I've even posted snips of such diagrams (not for vanilla 25, I think for Neo and 26) to various threads here in the last few months, talking about what it takes to get the fuel pump and FPCM up and going. Search these up and they will help get you started on doing the same with the vanilla 25 diagram. Hell, for all I know, I've done the same with that one in years past and have forgotten.
    • Yep...so unless someone posts up the answer you will need to probe from the ECU connector to the dash plug with a multi meter in continuity mode to trace the wires.  Note the ECU has multiple - and + (and across different key settings - Battery, IGN and Start) and most likely the power is fed from the connector(s) that is normally near the left hand headlight.
    • Thanks Duncan, I am actually just trying to get the Rb turning and running with the RB25DET S2 original loom itself  I am just trying to get it going outside the body and not thinking about the S15 or trying to match anything to the S15 loom at all I am only trying to see if anyone has done this and what pin they found to be the ignition trigger and ECU+/- on the dash connector, that's about it. Thanks
