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.

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.1982 Jaguar XJS V-12 Leaks oil like crazy. had the front seal changed but still leaks oil any suggestions?
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.
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.
dude poor you i dont know never tested it but put sealent and let desert sun bake for a while like weeks and dont drive inbetween the sun fixes leaks its different heat why donyt you tell the guy who fixed it to actually do that or else takem to small claims dont leave your car outa site with them after this!
You can put a motor oil dye in it, so you can see exactly where the leak is coming from.
