Like water, oil won’t compress in an engine. If the cylinders are full of oil, you’ll bend a rod and/or fracture a piston. A couple bumps of the starter told us the engine didn’t want to spin freely. We pulled the plugs and hit the starter to shoot oil out of the cylinders, but with the plugs reinstalled it still wouldn’t spin. The intake had filled with oil, so Hazel pulled the throttle body and sopped out a quart or so. McGee pulled the plugs once more and we blew the remaining oil out and got the engine to fire.
