Hi all, I rencently changed the clutch on my ep3 and while I was in there I thought I would do the crank shaft oil seal. Put it back together and I have now done around 400 miles, I have now got a bit of an oil leak where the gear box meets the block it's coming out the small black cover on the gear box (I will add pictures). I thought it could be the sump, took that off and renewed the gasket and I still seem to have a leak. Wanted to ask on here for advice before I go and take it all apart again. Back of the fly wheel is dry, is there any other places it could be coming from? The leak only happens when it is switched off.
