I thank you very much... for looking in to this issue for me. I guess I have to decide if I still want the car, or just get it fix. Once again I thank you.

The Jaguar v8 does not have a rocker arm or push rods, this is an overhead cam type engine.
4 cams on top of the heads which are driven by the timing chains, which are driven off the crank.
If your noise appears from the lower end, the most common issue is a main bearing in which case the car will need an engine. (the bearings go bad due to lack of oil circulation, the oil pick up tube in the oil pan gets clogged)
If the noise is upper and the car seems to run rough then the upper timing chain tensioner has broken and the chain has jumped causing the timing to be off.
If you start the car and you have a bad upper noise then the chain could be broken and by running the car you definitely will have valve damage.
