A GOOD RULE OF THUMB IS 10 LBS OF OIL PRESSURE FOR EVERY 1000 RPMS.(BIG DIFFERENCE BETWEEN 5 & 10 lbs AT 1000 RPMS) I'VE HAD THAT SAME PROBLEM A TIME OR TWO. AFTER YOU RULE OUT THE GAUGE & PULL THE OIL PAN TO CHECK THE OIL PUMP,(A REAL PAIN.. BUT POSSIBLE) PULL A COUPLE OF MAIN CAPS & LOOK AT YOUR BEARINGS. IF THERES ANY COPPER SHOWING OR YOUR CRANK JOURNALS ARE GROOVED OR THE FINISH DOESN'T LOOK POLISHED, PULL IT IMMEDIATLY & FIX IT. IF YOU DO.. DON'T FORGET TO SWAB OUT & CLEAN THE OIL GALLYS OR YOU WILL BE DOING IT AGAIN IN ANOTHER 2000 MILES. DON'T ASK HOW I KNOW.

LETS JUST SAY ALL THOSE LITTLE BEARING PARTICULS HAVE TO GO SOMEWHERE. I LIKE TO USE A SHOTGUN OR RIFLE CLEANING ROD WITH A BRONZE BRUSH ON IT. I ALWAYS HOPE FOR THE BEST & EXPECT THE WORST.
GOOD LUCK WITH IT. JOHN
