I don't think it is the sensors as I have two and the drop is consistent on=
 both. I have both the RWS sensor and the Dynon.   It seems to be having tr=
ouble getting in the mid 20 psi range.=20

I have a busy week so I think I am about to order new oil pump and O-ring a=
nd spacer  Hopefully it will arrive about the time my time frees up  I figu=
re it can't hurt and that will pretty much make everything in the engine ne=
w except the rotors and e-shaft.=20
