If the pump has been left to run and run because of a leak they can be just worn out, it's worth trying the piston ring first though...

Tank is visible under the drivers sill, early ones were alloy and lasted well, later ones are steel and rust out... Pete

If your going to keep the car then a new compressor will give you peace of mind... the bore on the compressor is a chemical lining, in an alloy cylinder, it does wear out and very quickly once the piston ring has worn out. There is no way of refurbishing a scored cylinder, and as far as I know, you can't buy a replacement cylinder without buying the whole pump.

Oh and £300 isn't a refurbished price, that's the new non Land Rover price.... It never ceases to amaze me just how much cheaper things get when they come without the LR sticker  Yesterday I couldn't spell Engineer... Today I are one!

Thanks again guys

Miggit, where would you get a new compressor from? Seen a few sellers for around £300-£320 online, am guessing they're all of the same quality?

It pays to do a google, as they discounted every now and then, I think mine came from Ribble Valley 4x4, but it might have been Island 4x4! I would do a search for RQL000014 and see what you can find...and remember that a supplier will only sell new.. if you go to the bay of fleas be careful... there are SH and "refurbished" which I wouldn't trust  Yesterday I couldn't spell Engineer...
