Question about Cars & Trucks
I pull the spark plug out and crank over the engine a few pulls and the cylinder is full of oil again,,,, whats wrong
What was the first thing that went wrong? Sounds to me like a valve stem is letting oil by it. When you say full of oil you dont mean clear full do you? Easiest way to test this is with a cylinder leak down test

Your valves in the cylinder head are not seating all the way or your piston rings are bad does the car smoke when it's running?

Are you getting spark from coil wire when cranking? If so, check the cap & rotor. If not, the most common failure is the crank sensor. If you have a 4,0, you can find it on the drivers side of the bellhousing, in line with the flywheel, just where it's annoying to work on. There is a test you can make, but I don't have the specific test values or the correct terminals to check. (you can find that info in any half decent manual.

If it ran good prior to spark plug replacement, then yes, I'd be looking real close at the plug wire to that particular spark plug. Perhaps it pulled apart inside boot upon removal. It may even be an indication that they are all getting weak, and time to think about a new set if it's originals.

With a service engine light blinking...don't drive it.
When replacing the spark plugs, double check that the boots on the coils are installed correctly. Check these again, and make sure to either listen for or feel a little click which tells you it's properly seated on the top of the spark plug. This is a common thing, happens all the time to people with TB's and Envoys. I've even done this myself.
In case you didn't know, # 1 cylinder is up front near the fan, then it runs in order to #6 at the firewall. Possibility....(don't take this as doubting you), maybe the wrong coil was replaced and one or more coil boots weren't set properly? Some things to check anyway.
