Chris,
 
    C= ertainly hope the front bearing is not the = culprit but check with Lynn Hanover about
the possibilty of pu= lling front stationary gear without disassembling engine...........I think<= /span>
it is possible as lo= ng as engine is not rotated before reassembly...........

I hesitate asking about this again, but I am too close to possibly fly= ing to drop the ball too much now.  I have a drop in oil pressure agai= n.  It has dropped from the high 60's or so to between 20 psi to 40 psi (20 to 30 at lower RPM and only up to around 40&#= 43; as I increase power).
