Hello everyone,
So I recently pulled the engine and transmission out of my 1989 Jaguar XJS. To my knowledge, this engine has not been worked on (in this depth) since it was made. That being said, there are alot of parts (especially plastic parts) that broke while I was working on it. This is my first time working on a Jaguar, so there are a few parts that I am not sure what they are called. Can anyone tell me the name of this broken part? Please note the plastic bell (for lack of a better description) that is laying at the bottom of the pic. The "bell" was attached to the piece directly above where it is laying. This part was attached to the rear and top (closest to the cab) of the V12 (original engine). If anyone can name it I would REALLY appreciate it. Thanks in advance! By the way me and my car are in Texas.

 

Looks like the oil pressure switch that operates the dashboard warning light

The entire assembly is the system that feeds oil from the sump to the camshafts. The thicker pipe brings pressurised oil from the pump, it goes to the casting and from there to each camshaft using the thinner pipes. On the casting are two senders: the cannister one sends the oil pressure signal to the gauge, the smaller one with the broken top sends the 'no pressure' oil warning light signal (as Doug said).

Both these things are notorious leakers, so it is a very good idea to change both while the thing is out. If you are redoing the engine a bit, there are other things to fix oil leaks that are a good idea to do in this area as well.
