so I noticed that a had a small oil stain under my 4runner and took a peak underneath. its bleeding from the clutch line but is it from the slave cylinder cause its dry? here's a pic, thanks in advance...

Any leak will be much easier to find if you clean up that gosh-awful mess first. As it is, you can't even tell what color of fluid is leaking; it could be engine oil or transmission oil (through a failed seal).

I'd try some engine degreaser (wash off with a garden hose), and a cheap plastic putty knife and scrub brush to finish. In addition to helping you find what the problem is, it's much more pleasant to be working where you're not up to your elbows in crud.

Mine leaks in the same spot. 99% sure it's not clutch fluid, since my clutch fluid has never moved or needed topping off. I think it is a rear main seal (engine oil) leak which makes it's way down clutch linkage and out that spot. Yours has been at it for a really long time to look that caked up. Do you have to top off between oil changes?

martinezoi

nah I don't have to top off on engine oil. I just took another peek and everything is bone dry, dirty, but dry. The only moisture is at that spot. its a very small leak, it leaves maybe a small drip or two overnite.


I took a look at the clutch reservoir and saw that its a just a tap under full. Im starting to think that it is the slave cylinder but I don't understand why its leaking at that spot where the fork boot is...

MudHippy

Definitely not the slave cylinder. The boot wouldn't be dry. It's either grease slung off the splines of the front driveshaft or the transmission input shaft seal is leaking.

Quick way to tell would be to smell it. Does it smell like gear oil?

Slight chance it also could be motor oil. But that would mean your clutch, flywheel, and every other thing in there is drenched in it too. NOT good...

martinezoi

thanks mudhippy, I'll check tomorrow for the color and smell of the oil. I'll see if I can see any other spot but from the looks of it, it seems like its just there.

I'll 2nd the grease from the drive shaft. Pretty easy to tell if it's grease or not. And mentioned above clean the area to pin-point it. That goes for any kind of leak.

martinezoi

went back and checked... its grease and its inside the boot too!?

How much grease do you pump in that fitting??

martinezoi

I didn't. ive only had the 4runner a few months

the slave cylinder is dry. its not leaking. this looks like an oil leak from within the bell housing. either from the trans input seal or the rear main seal.

MudHippy

Guess what? It's not any of those things.

Try reading threads first. Then posting your reply in them. Preferably without duplicating anything that's already been discussed. Saves everybody time.
That's fine. It won't hurt anything. There should actually be a little bit applied to where the SC push rod contacts the release arm, and where the release arm contacts the pivot point and diaphragm springs.

Ha ha....that's hilarious...

Like everyone else has said....degrease and clean to pinpoint where it's coming from. When I first saw the pic, I also thought it wasn't the slave cylinder because the boot is dry and you can see it's not coming from the location of the slave.

I would also say that it's coming from the direction of the front propeller shaft where the shaft meets the diff. What gives it away is that the drive shaft is wet also. Check out the flange yoke which is the first thing between the u joint and the differential and see if that is wet also. I'm thinking seal in the front diff and it's leaking gear oil. And if it's gear oil, it stinks...I compare it to cat urine. Not a good smell.

The only reason I think it's not grease is because it looks like oil...not grease. But I wouldn't rule out grease...I have a rear main oil seal leak and it comes from the top down...I think. I'm not looking at it right now. It just looks different from what you have there.

Check this pic for the drive shaft components.

martinezoi

thanks for everyone's input!

im gonna try to degrease and clean it all up so that I can pinpoint it out better and then see where I have my leak.

FGZ

Here's mine, and I have been pretty convinced it is engine oil coming out of there based on quantity and color.

martinezoi

Im gonna be checking to see what fluid it is, as I stated above.
anyone ever use this on their seals? (rear main or on the trannys main input)

Usually engine oil coming from the rear main will weep out of the bottom hole in the bellhousing. Is that hole clogged?

Would not use a sealer like that. If you have such a bad rear main leak you need to change the seal.

x2 on what Rust Bucket said: "Usually engine oil coming from the rear main will weep out of the bottom hole in the bellhousing. Is that hole clogged?"

I forgot...that's what mine is doing.
