andy i have the same problem at the mo, or i hope it is that seal. i have got it, now just needing to put it in,
but i am bidding on a new clutch kit on the bay at the mo, so hopefully will be doing that as well
if i get the clutch at the price i wanna pay it will be £50 all in for clutch kit and seal, so not bad, but i do have a nice oil patch on the road where i park mine

and i have just made myself another frontera, took about 10 mins. cutting and glueing it together
