Thats 100% gearbox oil look at the colour and it'll smell like shite. Bad news its leaking there too, thats a box split clean up and reseal to stop that. Theres no proper gasket between the bellhousing and the main gearbox casing its an instant gasket job and I guess that ones seen better days by the look of it.
They usually weap out the selector but thats not normal.

Thought it was gearbox oil but the engine oil is that clean i wasnt 100% sure, althou it does smell like af68 hydraulic oil = s**t lol
you reckon split the box off and seal it then?
When you say instant gasket.. i take it your meaning some sealent or hylomar type stuff?
Also, have you done this before, id like to know whats involved.
Thanks.

Ahh sorry i thought you had shortened it yourself lol, just had a quick search online and it does mention it somewhere.. also in a reno gearbox manual it mentions the use of loctite 518. Might have to order some in at work for a "job"
Dont think ill take the box out if im honest, just to much work, ill split it in the car and see how it goes from ther, mite make a start by draining the box later if i have time. Thanks for your input, ill be seeing you at a meet sometime i spose, not on the road with the 172 till mid august though!

TBH unless the gearbox oil was pissing out i wouldnt bother.. they always leak out the selector shaft anyway. Id just change the gearbox oil, clean the oil off the box and keep an eye on it. But thats upta you.
Il be at a meet sometime soon. Had lots on with the clio and its an embarresment at the min!

Im in 2 minds at the moment, ill have a look later and see whats involved. ive only got to split it enough to get some rag in and clean the face, then bang sum sealent in the lower half... ill see. have you done one before then?
That drip appears daily, and i think the drive would get messed up tbh lol
What you mean had lots on mate?
Theres a specific sealent renault sell in the a tube for this, probably just some generic sealent but its not very expensive so I got the proper stuff. Splitting the box is easy enough but its a bit fiddly to get back together. I wouldn't attempt it unless you've done gearbox internal work before and as said its a pig to get out in the first place.
Best idea would probably be get it out and then get a gearbox specialist to split and reseal it. Thats if its worth doing, depends how long its took to gather that ammount of oil?

Wait, which bit am i actualy sealing then, am i not just splitting it where the torx bolts are on the pics above and re sealing that part?, i could do that with it in the car if so.
Erm as for how long, it was all cleaned off and the pic taken the net day, with a few drips on the floor, You think its worth doing?

You can't get to all the bolts as some are inside the bellhousing and you don't want to be doing anything like that as you could dislogde no end of small parts that are in there. Even if you could I imagine you'd never be able to get it back together anyway as the detents will move so you wouldn't be able to get the gear shafts back into the journels at each end of the box.
Its a big job to reseal that!

Yes i have done one before..You could do it with the box still bolted to the engine... Remove the ring of torx bolts, and the selector shaft pin iirc.. but if u gonna do it you might aswell take the box out and do it on a bench, That way you can do a proper job.
The proper stuff for the job is renault caf.. theyll know what you mean.

Tbh, i did think i could do that but i wasnt about to argue with someone when i didnt know for sure, i think im just going to split it and seal it whilst its in the car mate, i havnt got the time or mainly, space to do it.
I may have to PM you for help if i get stuck if you dont mind a few questions.
Thanks very much

Also (pictured) where the gear selector shafts sit into the back of the bellhousing here there are 3 iirc detents that fit in between to stop you engaging 2 gears at the same time. The detents slide between cutouts in the selector shafts so when one gear is engaged a detent will stop the other shaft from moving to engage another gear until that one has been disengaged to release the detent to allow it to move.
As you can see they're not very deep and to open the box enough to reseal it you'll drop the shafts out of here and the detents will drop and you won't get the box back together, the shafts have to be reinserted in a specific order when you split the box to get them back in then drop the gearset in and put the main box section onto the bellhousing and get the external selector fork into the middle of the cutouts at the other end of the selector shafts where it acts upon.
Also as you can see the gear bearing journel beneath it isn't very deep either.
