Got a mystery, and looking for any advice:  My oil pressure is persistently in the 69 - 70 psi range in cruise, over 80 on takeoff with full power.  I've removed, disassembled, cleaned and examined the oil pressure regulator assembly on the back of the oil pump.  At the moment I have the adjusting screw backed out as far as it will go (usefully), and still am having these high oil pressures.  I even scavenged a spring from another engine to compare the spring tension, which seemed about the same from one to the other.  I'm really scratching my head.  Any ideas how to get this down?  Also, would running with these oil pressures actually present a problem, or cause long-term damage?  TCM recommends 30 - 60 in cruise, but state a 100 psi upper limit.
