i have a friend turn the engine slowly with a big wrench (i use the power steering pump, despite some warnings). When i see it coming i yell really loudly to stop! then he inches it (alway clockwise) until i can get the allen wrench in. Alternatively, i do it myself, which means getting really lucky, or crawling under the car 10 or 20 times. It's worth it, though!
