I'm guessing as it took a litre to top it up, it would have had a vacum if anything
I think it was more to do with the car sitting for a while in the heat.
I did about 10000K's before I changed the oil, just checking and topping it up every couple of weeks.
Got to the point it didn't take any at all, so I lashed out and bought some semi synthetic gear oil and it's as good as stopped leaking.
When I first noticed the leak (after I had done a 1000K's or so, it was not leaking pre purchase) it got that bad it would not have passed a RWC.
I will pull it all out one day and give it the once over but for the moment it's all good.
