DamirGTI 342 Posted February 23, 2008 (edited) Hello ! Yes most common places are driveshaft seals , next - oil drain plug , dif. cover , O ring seal in between the speedometer housing , 5-th gear cover on the end of the box on the wheel side and thats it me thinks (theres also gasket in the middle of the gearbox where the front and the rear box housings are bolted together but they rarely leak out from that area ..) The best way to find from where it leaks out is to clean/degrease the gearbox with solvent , wait until it dries out then start the car and look underneath for leaks at these areas ... or place a piece of cardboard underneath the engine/gearbox and leave it for a few hours or over night .. afterwards you'll be able to see from where it leaks by looking at the oil spots on the cardboard surface .. Are you sure that it's gearbox oil ? Damir Edited February 23, 2008 by DamirGTI Share this post Link to post Share on other sites
djinuk 2 Posted February 23, 2008 (edited) yep defiantly gearbox oil, the smell makes me churn. its quite a large leak, car sat for 30 mins not running and it left a puddle about 5 inches wide, , really hopping its a simple fix, just want my pug to work with me . are drive shaft seals hard to replace, never done it before. You say diff cover, not sure i have never spotted this, Edited February 23, 2008 by djinuk Share this post Link to post Share on other sites
djinuk 2 Posted February 23, 2008 i have no speedo cable at the moment (not even a cable present ) could this be the problem, with no cable present will the gearbox leak out of the top? Share this post Link to post Share on other sites
DamirGTI 342 Posted February 23, 2008 The seals are easy to remove/replace , but you need to pull the driveshafts out from the gearbox first .. This is the dif. cover : Rgs ! Damir Share this post Link to post Share on other sites
DamirGTI 342 Posted February 23, 2008 i have no speedo cable at the moment (not even a cable present ) could this be the problem, with no cable present will the gearbox leak out of the top? maybe if the hole is fully opened without the speedo gear inside ...

KRISKARRERA 2 1 Cars Posted February 23, 2008 What other parts of the gearbox have surfaces that mate together? Mine leaks a bit too. Share this post Link to post Share on other sites
welshpug 1,657 Posted February 23, 2008 if there is no cable present it will leak, if the drive gear is also missing then you've got a BIG leak! Share this post Link to post Share on other sites
djinuk 2 Posted February 23, 2008 Well today i went around the G-box and cleaned it off, i put in a speedo cable and went around did up the plugs a bit tighter, however i cam home after leaving the car for another few hours and indeed it is still leaking , looking at doing the diff housing, anybody want to give me a quick guide on how to go about doing the job, I took a glance and it looked like it would be a (drive shafts out) then unbolt it all , then seal and rebolt and then drop the drive shafts back in .(after dropping the gearbox oil of course), Would it be worth doing the drive shaft seals at the same time? are they hard to do, also what kind of sealant should i use on the diff housing?

danpug 1 Posted February 23, 2008 Yes you may as well do the seals at the same time, can be a pain to prise out. I always dive them a smear of oil then gently tap back in. Share this post Link to post Share on other sites
djinuk 2 Posted February 24, 2008 where should i get the drive shaft oil seals from, must i go genuine or will my local Motormania do the job. Also I am guessing it a job of dropping the gearbox oil, can i reuse this in anyway, can you fil the gearbox from the top, its just that its such fresh Share this post Link to post Share on other sites
uncle buck 0 Posted February 24, 2008 You don't have to fit genuine oil seals you will probably be able to get them from your local place...if not try GSF. Yeah you will have to drop the gearbox oil.....there's no reason why you can't reuse it, but if its been in for years now would be a good time to replace it. If you know how much oil the gearbox holds (Haynes manual) you can refill from the top....take out the breather or reverse light switch & pour in the correct amount of oil from there.... It's still wise to check the oil level after doing this just to be sure. Share this post Link to post Share on other sites
