Update… after our 20 “ of snow, it hit 50 degrees and I pulled the intake. I disconnected the three wires to the starter plus the alternator wire to avoid back feeding to a bad place. The starter got the jumper cables and jumper wires and turned the engine at about 1/3 speed. I had the plugs out so I tried a compression test on 1 and 2. 75 pounds on 1 and zero on 2. Bummer. Now I have to decide about finding a decent 3.0 motor or selling the x5. I’d be inclined to keep it and look for a motor and replace my wife’s 325. I’ll have to tear down the motor to see what happened.
