Hey guys I had my stagea rsfour on the hoist at work yesterday trying to find a leak from my engine, im new to these motors so im not 100% sure but I think its my trans cooler right where it comes out of the trans, just above the oil filter. Basically can anybody confirm this for me? Also if it is trans cooler is it better to go genuine Nissan or aftermarket?

That's not a trans cooler. That is the engine oil to water (coolant) heat exchanger. For warming up the oil faster and then kinda keeping it cool(er) when running normally.

It may be damaged, in which case getting it off pronto would be a dead necessity. But it may just be that it is leaking from the oil filter gasket. Give the area a degrease, take it for a drive, have another look.

Ok I was way off haha. I cleaned it up last night and will bring my car In again tonight to see exactly where it's coming from. Would it be worthwhile just replacing the whole thing rather than seeing how gaskets go? The motor is nearing 150, 000 km

You can't buy an aftermarket one, there's no such thing. Nissan might stock them, but they'd be a million dollars. They do have a reputation for failing internally and then mixing oil and water (obviously not good). When that happens people usually just get rid of them and/or replace with an external oil cooler (but then sadly losing the warming up aspect of it).

If it is leaking oil externally, I would be very surprised to see that it wasn't just leaking from the filter gasket.

Alright I guess I'll give Nissan a call tonight and get some gaskets, seems like I may as well go ahead and at least give that a go. Doesn't seem to be leakong internaly, no oil in the coolant and vice versa. Thanks for the help as well, much appreciated

Apart from the o-ring behind it that Scotty mentioned, the gasket you are interested in is not a Nissan supply. It is the standard rubber gasket that comes on every oil filter.

If it is leaking from there, then the chances are that the filter is just not tightened up enough, or at install time someone managed to damage the gasket or make it pop out of the groove that it is supposed to be in, or something similar.

Oh right, thought we were talking abouy a seperate gasket. I serviced it myself 2, 000 km ago and there was a little bit of oil around already, I'll check everythong again and degrease again and see how I go

Haven't pulled anything apart yet but it seems to be coming from behond the main housing for the oil warmer so im going to go with what I've been told and het and o ring for it and change it when I service my car

    • These coils draw 10amps that what i read online
    • I appreciate the detailed explanation, think I understand now. I spent the better part of last night reading what I could about shuffle and potential solutions. I had replaced the OEM twin turbo pipe with an alternate Y pipe that is separated further away from the turbo. The current one is from HKS and I had a previous pipe that was separated even further away, both have shuffle. I had heard that a divider can be welded in to the OEM pipe to remove turbulence, and figure that aftermarket pipes that are more separated would achieve the same thing. From what I read, most people with -10 turbos get shuffle due to their size, though it's a bit less common with -5s on a standard RB26. I think Nismoid mentioned somewhere it's because OEM recirculation piping is common in Australia with -5 cars. It seems that the recommendation tends to vary between a few options, which I've ordered in what I think is most feasible for me:  1. Retune the MAP or boost controller to try to eliminate shuffle 2. Install OEM recirculation piping 3. Something called a 'balance pipe' welded onto the exhaust manifolds. I don't know if kits for this are available, seems like pure fabrication work 4. simply go single turbo My current layout is as follows: Garrett 2860 -5s HKS Racing Suction intake MAF delete pipes HKS racing chamber intake piping hard intercooler piping,  ARC intercooler HKS SSQV BOV and pipe Haltech 2500 elite ECU and boost solenoid/controller HPI dump pipes OEM exhaust manifolds HKS VCAM step 1 and supporting head modifications Built 2.6 bottom end All OEM recirculation piping was removed, relevant areas sealed off I'll keep an eye out for any alternative solutions but can get started with this.  Only other question is, does shuffle harm the turbo (or anything else)? It seems like some people say your turbo shafts will explode because of the opposing forces after a while and others say they just live with it and adjust their pedal foot accordingly. 
    • That worked out PERFECTLY! Thank you big time to JJ. He was able to swap me his stock diff. He drove all the way to me as well. Killer! Removal & install was pretty straightforward. The diff itself is HEAVY. So that’s a 2 man job.  Man does the car drive nice now! Couldn’t have worked out any better 👌
    • I'm interested,do you still have it?
