Welcome to old Jaguar's Large drip pans sit under many. Now before you get in way to deep have the engine compression tested. Worn pistion rings could cause to much crank case pressure. If the compression is good start checking the Positive Crank Case Ventilation system. For collapsed hoses plugged PVC valves. Ahd Most of all Find someone who doesnot want to pull the v-12 and put in a chevy motor. Old Jaguar Mechanics are very hard to find. There is someting so smooth about V-12

Yes, in general, Jags stop leaking when they are out of oil. However, if your leakage is excessive, you're going to have to locate the leak and repair it. On a V12, the rear crank seal is a frequent culprit. This can be repaired in place using the rope seal from a Ford 460. You can find the procedure here:

Other seals are more straightforward. The key is locating the leak.
Whatever you do, don't even think about a Chevy motor. If it comes to that, sell the car to someone who cares.

Rubber oil seals tend to go hard and brittle over time - the ones you have not changed are likely not working well in a car that age. You can get oil additives that contain substances to re-plasticise and soften the oil seals, which can dramatically improve things in older engines. If you mean Gaskets, they are a different thing - recurring leaks are typically due to not cleaning all traces of the old gasket & any sealing compounds off the surfaces, or one of the parts is deformed (eg. by over-tightening a sump or cam / rocker cover). (Generally, 'Oil seals' are to moving parts, Gaskets are between fixed parts). If you need further info, post another question and say which seal or gasket you are having trouble with.

I suggest you put it up on a hoist and take a look to see for yourself where the oil is leaking from. If it's the front seal, take it back to the place that changed it. Actually, even if it's not the front seal take it back to them and complain. They will very quickly point out where the oil is leaking from if it's not the front seal.

You can put a motor oil dye in it, so you can see exactly where the leak is coming from.

J.P. has it right. Jags from the early to late 80's and even the early 90's are like the late 70's and 80's corvettes. You look at them wrong and they break.
