There is nothing worse than getting in to your beautiful looking Jaguar outside a nice restaurant with your wife and a couple of friends only to start it up and be engulfed in a cloud of blue/grey smoke! It sort of spoils the moment a bit! Trust me it will get this bad and in my experience sooner rather than later, once the seals start to go they will get progressively worse.
How long they last will depend on the ware in the valve guides and the qulity of the new seals.
On a new car with factory seals 100,000 miles + is not unusual. (I have changed them for the first time on 130,000 mile cars.)
In short I would recommend biting the built and doing the job.
