I think mine's bad too...
I decided to check my AOS today and did the oil cap removal trick. There was a bit of suction and the engine began to stutter once the cap was off. Is that a sign of failure or should it be almost impossible to take off the oil cap? I was easy to take off when I initially removed it.
