Update.. today I had the day off and planned on doing the compression test. I have a dead battery. Put it on charge and now get loud clicks about one second apart. I put my 32mm on the fan bolt and turned the motor via wrench. Seems normal. Easy since the plugs were out. I put the compression tester on a couple cylinders and there is some compression while turning with a wrench slowly. I believe I have a battery drain due to a RR air suspension leak or some other parasitic situation. I plan on jumping the vehicle to see if it cranks then. Any thoughts so far?
The borescope just showed the tops of pistons and the plugs looked a bit wet/oily but with everything that happened within the 2 minutes of chaos, i'm not surprised.
