I have recently bought the car and it had a bit of work done to it including having a reconditioned rallye gearbox and clutch ect fitted. I've been driving it for about a month and it seems fine in all gears. I've used the search button and from what I've read it sounds like it could be a seal/ o ring that's gone maybe?
I was kind of hoping it would just be the drain plug but I don't think it is. I'm also not sure weather it's engine oil or gearbox oil that's seeping out? I'm just after a bit of info really to see if anyone else has had the same problem or could advise me on what it could be before I have to take it to someone, which I don't want to do as I'd rather do it myself but I've never had a gearbox off one before. Any help or advice would be much appreciated.
