OK Frank thanks. Interestingly there's an S type sump on e-bay today, and a groove is visible in the flange. Although the mating flange is the same as the Mondeo (just a slight variation), the lower half is completely different. The Jag oil pump take off is at the front (when the engine is in-line), and the rear part tapers to a much more shallow profile. If this motor is transverse in the Jag that means with the gearbox on the right(nearside)as you peer under the bonnet, the deep section is to the left (offside). That isn't suitable for a transplant onto a Mog engine, because we really don't want the deepest part at the front!!!!!
The question remains if there are any V6 Jags which use a centre pick up - and you know what that looks like already.
