My other car is a MINI!!!!
can I assume from the amazing nick-name that could only ever have come from a man named Les, that this is TJ?
New rack is the quick and easy solution mate, if it's leaking from behind the gaitor it'll be fecked, can get recon racks for about £110, or take your chances on a second hand one.
Yours being an AGU without traction control would benefit hugely from a TT225/S3 rack though, 2.7 turns lock to lock instead of 3.4. Last one I bought I paid £80 second hand.
That's the way I'd be heading if I were you.
Labour wise, it's about 2 hours work on the driveway with basic tools and axle stands.
