Well, it has been a little more than a year (or three), and I only torqued it once then.  I'm going to go the route that there isn't enough pressure holding the plates together.

On a better note, the engine is spitting oil out the sides because it is making more power.  As I've been learning to twist the right Megatune knobs, I've had to back up, reconfigure and then retune multiple times.  But I've finally got it running smooth from an idle of 1500 to 5460.

Oh, and I got one of my wings put on today!!!
