If you checked it with a mechanical pump and that is the result, it sounds like a bad pump.

I would recommend checking the oil pump. That would be my first guess based on your description. Other than that, you could have a worn out engine (bearings) that could cause the pressure to be low or even the pick-up tube on the oil pump could be plugged.

I THINK J and N MEANT IN THE BEGINNING TO CHECK PRESSURE WITH A MECHANICAL GAUGE---SCREWED INTO THE HOLE THE SENDER IS IN NOW

(NOT CHECK IT WITH A "MECHANICAL PUMP" AS HE MISTAKENLY SAID)

I GOT MINE ON A PLASTIC TUBE----I CAN RUN IT UNDER THE HOOD OR THRU A HOLE IN MY FIREWALL

YOU CAN BUY A "UNDER DASH" UNIT AND USE IT TEMPORARY LIKE MINE----OR YOU COULD MOUNT IT PERMANENTLY (IF YOU GO THIS ROUTE--PICK OUT ONE YOU LIKE IT'S LOOKS!)

When you remove it, make sure the pick up tube isn't plugged. That could cause the problem too. Let me know if you have questions.

If the sound isn't as bad with 20/50 oil, chances are the bearings are you have excessive play in the bearings. Check that.

Before replacing the rod and main bearings, check to see if they have excessive wear. You need to get a product called plastagauge. It goes between the bearing and end cap. You tighten the end cap and it causes the plastagauge to crush. The more it crushes, the tighter the bearing is. There is a wear gauge that is provided to identify if there is a problem or not.

Yes, you can replace rod bearings, but main bearings are a different story because the crank has to come out. The rods can be moved. Whatever you do, mark the end caps so that you can replace them facing the same direction and on the same rod.
