SOURCE: thick blue smoke. no oil
Hi! Chris, There are many causes of oil burning or exhaust smoke. There are three different causes of normal oil burning, 1; worn valve guides (smoking during deceleration), 2; worn cylinders and piston rings (smoking during acceleration), 3; split or worn out valve seal, or damaged intake manifold gasket (smoking all the time). Of course there are several variables in this equation. Sometimes coolant can also get into a cylinder and cause a blueish smoke. If you remove the spark plugs and use a pressure pump on the coolant system (radiator), coolant should leak into the intake manifold or cylinder. Coolant leaking into the intake manifold will leak into several cylinder through the valves. So, what year and how many miles are on the Jaguar?

I had the same problem. I changed the pcv valve and checked the hose. It still did the same thing. Then I checked the metal tubing that the hose connects to and found it was full of hardened gunk. I sprayed PB Blaster into the tube let it soak for awhile. Then took an old choke cable, put it on a drill and ran it into the tube like a drain snake. It took a while of doing this over and over but eventually got it cleared out. Now, no more oil all over the engine and hood compartment.

SOURCE: blue smoke from exhaust
Blue smoke is a sign that oil is being burnt in the combustion process. It is normally a sign of high engine mileage. Definately a compression test would be in order to try to pinpoint the cause. In addition to high mileage it could be something like a broken piston ring or a valve not seating properly. It might also be possible that you turbo has a bad seal and is putting oil into the air as it spins. This problem should definately be looked into soon. Hope this helps.
