Clio 172 cup gearbox leak (o/s diff)

[St03 cup]

Hey guys I've recently bought a Clio 172 cup and noticed a few weeks bk that it was slowly leaking gearbox oil from the drivers side .. On inspection the big diff seal was damage so I replaced this but a few weeks on and I noticed the leak again but is actually coming out more than ever . I'm unsure as the why this is any ideas?appreciate any help as I've heard u guys know ur stuff

Come on guys surely someone can help !!!

I think i may have a similar problem my car has been parked up for 2 years and when i got it out i noticed oil on the floor not a lot but enough to be a leak, cheked the engine and was still full so dropped the bottom tray and thye bottom of the gear bos was dripping haven't managed to find the leak yet checked the plug and filling hole and NS DS and all good so suspectmine could be leaking from the right hand side
