Losing Oil Pressure

I have twin Crusader 270 engines - 350 Chevy Block.

Heading down from Knoxville, Tn. area I noticed my stbd engine which normally held Oil Pressure at about 55 psi, started slowly losing pressure.
Recently. I had made a new dashboard with all instruments and on short play trips of about 3 or 4 hours i noticed that it was getting lower. We were giving the engines a good run the other day because we are planning to head further south. My starting oil pressure is the old 55 -60 PSI. After about an hour or so it dropped down to about 50 and then to about 45. In idle it dropped below 30.

I tried to find a reliable mechanic but they are hard to come by. One was supposed to come by today but never called or showed.

Until he finally gets here, I am in a panic. My oil seems clean, there is hardly any smoke, I'm not using any oil and the engine seems relatively quiet and runs smooth.

Anyone have any idea what this could be?
I'm in panic mode, not just because of the expense of repairs, but also, If we dont leave soon we will probably have to stay till spring.

Thanks in advance
