Put her in the barn back in mid October, battery was fully charged and plugged in my CTek, and closed the barn door.
Weather was pretty good yesterday, temps finally reached the low 70's, so I though I'd open the barn door to see if she was still there.
She was, so I took off the cover, climbed in, turned the engine over for about 30 seconds, then started her up. Her response was perfect, ran for 20 minutes like she never was asleep for the past 6 months. No red lights came on, no messages appeared on the screen, and all gauges worked like they should. No leaks on the floor,, and very little blue smoke when started, cleared up in less than a minute.
We still have snow in the forecast so she'll stay covered for another couple of weeks, but it sure felt good to see her in a good mood.

 

Yes indeed, life with a fully charged battery in the Jaguar is a very sweet thing.

 

Not sure about 5.0s but the 4.2 will smoke once in a while. Mine has done it and my AjV8 4.4 in the Rover does it once in a while. Its a good idea to remove the TB and clean the intake once in a while.
