I cant pinpoint where this leak is coming from..
Ever since I changed my gearbox oil I am getting a leak that looks like its dripping down the side of the case...
I did not overfill it, and even removed the fill plug to double check.

Odds are it is coming from the vent hole on top of the gearbox. Leaks a bit especially after a fill and in hot weather.Quote:

It's just going to weep. Some folk have gone to great lengths with extended breathers etc. but I just let it rustproof my crossmember.
Other usual suspects are the selector shaft seals and the seals for the shifter detent springs. Both of these will leak down the side of the gearbox.

With Transmission top cover off. Note that the detent balls are there, but the springs and seals are removed. The detent seals are the same setup as the selector seals and fit in the groove on the edge of the transmission:

A non-leaky Land Rover gearbox, tells you that there is no oil in the gearbox, and it is now time to refill, once again. :p
Remember that a Land Rover does not drip oil, it marks its territory. :rolleyes:
Leaky engine and gearbox, also called sling greasing, is a concept invented by the English to prevent rust in the undercarriage and works as you drive, it took them years to develop. :D
;) Sorry I couldn't help it. To be honest, It's a very rare sight to see a non-leaky Series Land Rover gearbox or engine, and if it doesn't it's usually only for at short time, after you spent hours changing the oil seals, I do know a guy who brags about his Land Rover doesn't leak, but he doesn't drive it either.
SAFEAIR...
thanks for the post... that will really help..
I did the rear output seal today and rebuilt the handbrake since there wasnt much left of it anyway.. pars of the adjuster were broken and sitting at the bottom of the drum..
I think I will go after the shaft and detent seals next week..
I came to grips with the fact that these things are going to leak somewhere, hence my screen name....
You can either spend time chasing your tail or just have fun and drive the thing.
Im of the same mind - and not because I have the expertise of "I Leak Oil" but because trying to solve the leaks is just too darned frustrating...Quote:

Keep 'em topped up and enjoy driving it.
IM not opposed to that. god knows I have owned enough trucks in my life where this is the case...Quote:

Believe me.. after doing it once, im not looking forward to doing it again..
Hello,
I am tracing the oil leak in S2a transmission after getting oil pond of size 2x3 feets through one month of stop during Summar (45C) :confused: suspecting worn part is their.
Clean the gearbox/transfercase and fill it with oil "140" I found the front and back of transfer case is dropping the newly added oil. The question here are these leak due to O seal? Are replacing would stop the leak?
(My plan to repair worn and leave design matter; therefore, 1st week fill the transmission with oil, clean the outside serface and monitor any leak for a week (currently in it), 2nd week drive it at low speed and monitor leak source, 3rd week drive it at full speed+overdrive and monitor the leak).
Looking for hint on transfer case leak. Thanks.
Most of our local auto parts stores sell UV dye and a UV magnifying light. Pour a bit of dye into the oil, drive around, and take a look. It is magical for finding stuff like this.
I'd be afraid that my engine bay would look like a cheap hotel room under a black light.
Scary.
and the garage and driveway like a ****** scene . . .Quote:

A cool trick would be to 3D print or machine a set of retainers that could allow for the heater hose rings to go over the existing selector seals. This would prevent having to split the top case cover.
While I was under there I noticed leaks from the transfer case from the selector seal and transfer shaft cover. I put another o-ring over the original selector seal and 4WD pin. I put RTV on the cover and let it set overnight. So far it seems to have handled the majority of the puddles. I still have a small drip from the bottom transfer case cover, but that is normal. I do have a Toro overdrive which has some leaking issues which I need to tackle next.
I have not bought any oil seals for some time but the OEM seals used to be leather with a spring around them. i've saved some of them and may elect to re-use them as opposed to the regular rubber ones, when ever i get around to dealing with it but i usually just top up the boxes in the summer and let it leak !! I miss the E brake though so will prob deal with that sometime.
