do what i did, pop down to your local halford and buy gungum exhaust putty, warm the sump up by driving about for a bit, then cover the sump in the putty, leave for about an hour then drive about for 10mins to harden then putty. ive had my car for 3months now, its came with a hole in the sump which would go through a litre a day. havent had any problems since doing this, cheap way to fix, if you havent got much cash
