Oil Cooler leak ? TD5

[Rosscoe68]

got some oil in my water and my first thought was the oil cooler ?. looking at the Rave cd it looks a pretty straight forward job getting it out, but Rave doesnt mention if the turbo needs to come out first, although it shows in the pictures no turbo, do i assume the turbo has to come off first?
i guess this might be a good time to take theex mani off and do thepreventative stud mods at the same time ?

anyone done one of these ?

not sure about a disco, you can get it out of a deefer without pulling the turbo but personally Id pull the turbo just on the count of the extra visability and access you get into the area so you can make sure you dont screw it up or mis torque things while your in there.
