ok if I just leave it like that and keep pumping t case oil into the t case every week or two?, is it okay? Because it's quite a nasty job to do to fix it.
Evo are miraculous in how they don't leak. They have so many seals that could. Its a testimony to the quality they put into this car.
You say you replaced the clutch a couple of months ago. Your wanting to avoid pulling the transfer case suggests a shop did it. If that's the case why wasn't it their responsibility back then? It didn't leak before right? Anyway, probably too late to come back on them now.
The transfer holds only 0.6 quarts of oil. You are playing with disaster, especially if you road trip. I'm about the laziest person on earth and I don't consider you suggested fix a good one.
I agree a leak at the t-case....if you take a long trip...forget to top it off....leak gets worse and you don't know it...
next thing you know, you have the death whine.

That's risky, dude.
even now it's got a little bit of whine noise when I on fourth gear around 2300-2500 rpm. But not very loud and only appear to have the noise at 2300-2500 rpm

yeah I know I should fix it as soon as possible but I'm thinking should I just rebuild it straight away or just fix the seals and keep driving it until the trans case dead?
so I just put a little bit on where it leaks from?
Did you fix it that problem when you had the same problem as me? Mine is same as you every time I parked it drop a very little bit of oil on the ground.
Yes that's the RTV gasket I was referring to but I think you miss understood on how to use it. Your not going to use it to stop a leak but to help hold the o ring in place as you install the tcase back . You can also use grease as mentioned earlier. Now that i remember, I think I used grease to hold mine in.
The slight noise you have is not death whine. The death wine noise is always present and increases with speed. It's not rpm dependent.
My little o-ring is glued to the transfer case using 3M weather strip adhesive (the yellow stuff). I'm amazed at how often I get to view that o-ring. It stays in place. But it could be the big o-ring got nicked during reassembly. I'd suggest having both on hand if you decide to have this fixed.

+1 they are super cheap. No harm in replacing both!

I see, okay I'll try this stuff when I install the o ring.
Thanks man I'm getting check up for the noise hopefully it's not the dead whine noise

yeah think I need to use something to hold it in placed if I fix it don't want to leak again after few weeks
I've recently found my TC leaking from what appears to be the breather. No whine or any unusual noises, I think I caught it quickly. The closest thing I have found searching the forum is that seals between the trans and TC may leak and allow pressurized tranny fluid into the TC causing it to overflow and leak out the breather. I plan to first check the tranny fluid level to see if it's low. It was rebuilt within the last year and the car doesn't leak a drop of fluid (until now) so it shouldn't be low. If it is it's safe to assume it's in the TC. Next I plan to check the level in the TC. If it's high that is further evidence that the tranny is leaking into it.
I read there are 2-3 o-rings that can fail and allow this leak to occur. First question, does anyone else know of this situation? Second, are the two o-rings listed above the o-rings in question (I've also attached an image from the manual)? Third question, how would these two o-rings allow tranny fluid into the transfer case? There doesn't appear to be any pathway from these o-rings into the T-case.
If it's not these o-rings I need to replace (assuming the above is my problem) which o-rings or seals do I need to replace?

I've never seen them fail, but they are only rubber or vitron, so it's possible. I have seen installs where the small o-ring falls out during install. The larger ones don't usually cause a problem but, again, anything is possible. How long ago was everything installed and when did you start noticing the leak? I can't see how a missing o-ring would cause anything to pressurize; it should just leak. Maybe I'm missing something too? LOL I'm just trying to walk myself through it, logically. I dunno, man.
I haven't heard of leaking from the vent, so sub'd for a fix.
Owned the car for about 3 years. Had the trans and clutch rebuilt about a year ago. Been working fine, not a drop since. Gave it a bit of a workout the morning of 6/2/18 because I had to use up some fuel (can't have more than 1/4 tank for the show), had it in the Scottsdale HIN show that day and on the way home after the show started smelling the gear oil at the stop lights. Looked under it when I got home and noticed the oil on the exhaust under the T-case. Not dripping a lot, even after sitting for a week and a half just a very small "puddle" under it. I can see it around the breather and of course it has dripped down around on a few parts.
Here's a link to the thread where I read about the tranny fluid possibly leaking into the t-case.
I'm getting check up for the noise hopefully it's not the dead whine noise
