Hi all, I have a fairly substantial leak coming from the rear attesa system.. I have stuck my head under there and there appears To be the attesa unit above the diff and there is a lot of fluid on a wiring plug coming out of the unit. Has anyone got any pics of the unit out of the car and if it is possible fluid is coming from a switch?

Any help would be great!!

Thanks

Thanks endless, mine looks like it's leaking from the other side, looking from the drivers side just in front of the diff. Thanks for the pic.. It gives me a much better idea of what I'm looking at. Did you take this off the car without taking the diff out? Or did you need to remove the diff?

I'm not sure I can fix the leak with it still on the car.. I'm dreading having to take it out though.

That's not my picture, just a borrowed one!

You have to remove the diff to get to it. I will check mine on drivers side to see if it is wet there, mine is a pretty decent leak too as it drained the reservoir last time enough for the 4WD light to come on after a short time (only just got the system working due to other issues)

Unfortunately for me, i have JUST replaced all the diff mounts so i had access to it but didn't know it was leaking! :(

Mine is the same, I fill the reservoir and within a couple if days it's almost empty... Leaving behind a trail of everywhere I've been over the two days. The light is on and I haven't refilled it, of late because it empties too quick. Is it possible the unit would have Shat itself with no fluid? I'm thinking when I get it off I should probably just replace it with a known working unit. Problem is getting the car off the road as I have no spare..

Pull your 4WD fuse for now as this will stop it from leaking out any more fluid. I'd think the unit would be working as long as you didn't run it bone dry. I'd bleed it once leak fixed though.

Just checked drivers side on mine... looks dry. Mines definitely the other side.

I found the bleed mico was talking about, here is a useful bleeding guide showing location.

Great work mate, i look forawrd to getting the sucker off and having a look at it. If the fluid is traveling along the wiring then that could be my problem too. I reckon before I take it off I'll fill the reservoir, jack it up and then remove the white clip under the dash to actuate the pump.. Then just hope I can see the leak and be able to get to it with it still in the car. I hope the pump is still working!

      Cheers. Skyline is back on the menu, can’t get rid of it. It’s like a child you don’t want, or herpes

      I got back to Japan in January and was keen to get back on track as quickly as possible. Europe is god-awful for track accessibility (by comparison), so I picked up a first-gen GT86 in December just to have something I could jump into right away. The Skyline came over in a container this time and landed in early January. It was a bit battered after Europe, though—I refused to do anything beyond essential upkeep while it was over there. The clutch master cylinder gave out, and so did the power steering. I didn’t even bother changing the oil; it was the same stuff that went in just before I left Japan the first time. Naughty. Power steering parts would’ve cost double with shipping and taxes, so knowing I’d be heading back to Japan, I just postponed it and powered through the arm workout. It took a solid three months to get the car back on the road. Registration was a nightmare this time around. There were a bunch of BS fees to navigate, and sourcing parts was a headache. I needed stock seats for shaken, mistakenly blew 34k JPY on some ENR34 seats—which, of course, didn’t fit—then ended up having the car’s technical sheet amended to register it as a two-seater with the Brides. Then there’s the GT86. Amazing car. Does everything I want it to do. Parts are cheap, easy to find, and I don’t care what anyone says—it’s super rewarding to drive. I’ve done a few basic mods: diff ratio, coilovers, discs, pads, seat, etc. It already had a new exhaust manifold and the 180kph limiter removed, so I assume it’s running some kind of map. I’ve just been thrashing it at the track non-stop—mostly Fuji Speedway now, since I need something with higher speed after all that autobahn time. The wheels on the R34 always pissed me off—too big, and it was a nightmare getting tires to fit properly under the arches. So I threw in the towel and bought something that fits better. Looks way cleaner too (at least to me)—less hotboy, less attention-seeking. Still an R34, though. Now for future plans. There are a few things still outstanding with the car. First up, the rear subframe needs an overhaul—that’s priority one. Next, I need to figure out an engine rebuild plan. No timeline yet, but I want to keep it economical—not cutting corners, just not throwing tens of thousands at a mechanic I can barely communicate with. And finally, paint. Plus a bit of tidying up here and there.

      Nope, needed to clearance under the bar a little with a heat gun, a 1/2" extension as the "clearancer", and big hammer, I was aware of this from the onset, they fit a 2.0 with this intake no problems, but, the 2.5 is around 15mm taller than a 2.0, so "clearancing" was required  It "just" touched when test fitting, now, I have about 10mm of clearance  You cannot see where it was done, and so far, there's no contact when giving it the beans Happy days

      It's been a while since I've updated this thread. The last year (and some) has been very hectic. In the second-half of 2024 I took the R34 on a trip through Germany, Italy, France and Switzerland - it was f*cking great. I got a little annoyed with the attention the car was getting around Europe and really didn't drive it that much. I could barely work on the car since I was living in an inner-city apartment (with underground parking). During the trip, the car lost power steering in France - split hose - and I ended up driving around 4,000kms with no power steering.  There were a few Nurburgring trips here and there, but in total the R34 amassed just shy of 7,000kms on European roads. Long story short, I broke up with the reason I was transferred to Europe for and requested to be moved back to Japan. The E90, loved it. It was a sunk cost of around EUR 10,000 and I sold it to a friend for EUR 1,500 just to get rid of it quickly. Trust me, moving countries f*cking sucks and I could not be bothered to be as methodical as I was the first time around.
