The angle of the piston keeps the camera on the cylinder wall just below the plug hole but perpendicular to the hole. The camera is 9 MM X about 1" to maybe 1-1/2 so the only way to grab it is by the ends to take it out but I can't grab the ends because it keeps rolling to the bottom of the plug hole. I tried jacking on side of the car up to relieve some of the angle of the piston it helped but not enough. I'll get it out and it should be easier now that the valve train problem is out of my head.
