Oil Leak

[stasis]

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.

first just make sure that line is in tight, 17mm spanner (preferably flare nut style).

Ok I took some pics today while i changed the rear upper link. i checked the bolt with the 17,, spanner and it was tight. And her is a picture of it. See what you guys think. It begin to form droplets and soon it will drip onto the floor

that had to be waht it was

it doesnt look liek an input shaft leak

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

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.

if i take off the line, would it suck in air then i have to bleed it? Cos i know its a bitch to bleed that line.

hey dude my mates had been out at one stage and was cross threaded in always leaked as it split the flange that it sealed on.

hAD to cut it and reflare it just a thing to look at.

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?

[beastien]

You will unfortunately.

hmm ok

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.
