Guys ,

took the car in for alignment 2 weeks ago after i changed my suspension. While the car was up on the hoist i noticed in the middle of the undercarraige theres a bis pot of oil. So i slipped underneath the car when i got home. i can pinpoint where the oil patch is from. Its located directly underneath at the start rear tail shaft. Whats that thingy right underneath the rear tail shaft?! It looks like a wiper motor and its got an insulated tunbe running to the rear of the car. The oil is not dripping on the floor when parked for long periods. Its just annoying to see the patch of oil on the car itself. I hope somebody is able to shed some light onto this.

Since its seeping oil, will it affects any of the components?!

Thanks guys

Hey Yudy its the attessa hydraulic actuator it presses the 4wd clutch packs when its supplied pressure from the attessa pump above the rear diff by pushing fluid through the line u see screwed into the back of the actuator. Is it leaking from the line or between the actuator and the tf case?

i cant remember if the unit has a gasket between it and the tf case, if so then its obviously stuffed and u need a new one (if its leaking from there)

i will take a look tommorow and will try to take a couple of pics to be uploaded.

Although, after changing the coilovers before i discovered the leak. I did a few tight turns and the rear seams to disengaged somthing. It happened tiwce, and once when i was backing out from a parking lotwhile turning and it also seemed to disengaged somthing. None of the warning lights came on. The fluid level at the back of the boot is at normal levels.

yep - its your atessa pressure line. The main issue is the fact that it will probably only leak when it is running (ie - puttting any poer to the front wheels) which will make it hard to see in action, unless you are the sort of person who doesn't mind sticking their head under a moving vehicle :D

Take the line off and have a good look at the sealing area. You may be able to use some teflon tape if it is a tapered thread, but if its a crush fitting you might have to take it down to EnZed or somewhere like it and get them to slap a new fitting on the end.

Could also be the seal under the cap, that the line goes into.

The hose fitting usually wont leak if it's in good nik and tight.

you mean the o ring in thecap? If i take off the cap replace the oring and put it back on, will i need to bleed the system?

While changing oxy sensor yesterday I found a leak from this same position. Has anybody taken the body off to know if there is an oring or gasket seal. I degreased under car ready to reseal. Any sizes and numbers would help before I crack it open. Thanks.

    • sold listed as a Tomei LSD 1.5 Way For 1998+ Nissan Skyline ER34 25GT RB25DE w/Open R200 https://www.ebay.com/itm/174006114594?campid=5338967980&mkevt=1&mkcid=1&toolid=10050&customid=&mkrid=711-53200-19255-0&loc_physical_ms=108689&loc_interest_ms=&campid=5338967980&mkevt=1&mkcid=1&toolid=10050&customid=71883f2ccc571356e0a757bc7adfdde2&mkrid=710-53481-19255-0&loc_physical_ms=108689&loc_interest_ms= it went in like butter all gears, alignment, back lash etc, rotation and clearances correct, and if rolling all rotates smooth and free when coasting down road , clutch in or out over 10 mph smooth... its the binding, clunking and jerking from a stop that is most concerning, also seems like its going to tear the tires off in 10 miles of normal road driving. 
    • What 1.5 way? There's no such thing really as a 1.5 way, just different ways of explaining 2 ways with different ramp rates. HOWEVER. In any driving in a straight line your 1.5 or 2 or 1.7 way should have no clunking at all. With the clutch fully depressed the diff should be silent (unless it's welded but I'm assuming it's not). Something aint right here.
    • Clutch is a spec brand, new clutch system,( PP, flywheel, friction disc, etc. pull type) installed 100 miles ago, with no problems.
    • looking for some help and maybe some insight on others experience with a new LSD. R34 GT ran and drove beautifully, but always alot of grip loss due to the open R200 rear end, so I just installed a new 1.5 LSD way into the stock open R200 for a ER34. Simple. Everything seemed right. I test drove for the first time this weekend. as I started to back out the garage the first time slowly with tires straight it sounded and felt like I had a loose or half disconnected drive shaft...that was clucking around loose and shaking entire vehicle, and making it feel like the trans clutch was spontaneously slipping then grabbing very roughly while just letting out pedal slowly. I backed it out went to pull forward with the same noise, shake and slip grab feeling with hesitation, I turned the tires to back out more and then pulled ahead some same thing but worst because of added wheel resistance (which that I expected) puzzled … pulling it back in checking everything over and finding nothing wrong, I tried it the next day. same thing, couldn’t believe how it shook everything again making a terrible noise and making it feel like the trans clutch was slipping and grabbing, but I got it out of garage into the driveway, got it straight, drove forward and then reveres a few times in a straight line everything shaking , causing what felt like clutch slip and grab every time, sounded like right behind front driver tire and I could feel it in the floor board with my feet,... worst right when beginning to let clutch pedal out to engage slightly, shuttering and sounding terrible along the way…I managed to slowly get down the road, babying it the whole way, once I was rolling (out of 1st) seemed to be better and between shifts, then clutch felt closer to normal…not slip/ grab etc., but back down to any stop, straight road or turning, same thing. Made no difference if all tires were straight or if I was turning. All other gauge read out correct. with in 2 miles as planned I reached the empty parking lot and performed the break in procedure that came with lsd, essentially to drive in a figure 8 a bunch.  Did this, binding chattering, and shaking the car the whole way. I drove it back home seemed somewhat normal once I was in straight line and past 10 mph or so, and I know it will “bind” on corners and cause some tires squeal when turning especially from a stop, but when I begin to move it still causes what feels like the trans clutch to slip and jerk badly as well as shaking the entire car, and sounds terrible, that I didn’t expect. I used the fluid they supplied with LSD kit and did the breaking, planning to change fluid as they suggest after breaking, but wondering will it get smoother or less aggressive with use? maybe a 1.5 is just too aggressive for normal road driving?   I have a LSD that I put in my 71 cuda when I restored it, with amazing smooth , quite yet effective results. Different style LSD but that ones a joy to drive. maybe expecting too much from this R200?
