Default Oil pressure drops (random)

I hope I am posting this in the right area. If not, I apologize.

I looked all over the forums and did not find anyone else with this same issue.

My 2001 Bonny (NA) has developed an oil pressure issue. A couple of weeks ago my oil pressure bottomed out while driving. High RPMs did help pick the pressure up a bit. There were no noises associated with the problem. I changed the oil pressure switch, and everything seemed fine. I also changed the oil and filter, as it was definitely due.

Now, I get random FULL drops of the oil pressure indicator accompanied with the usual "ding ding ding" audible warning. The loss of pressure is only momentary, say, one to two seconds. There seem to be no directly related circumstances when it happens either, although it more often than not it is under acceleration, just not always. Any ideas?

Thanks for reading my book!

get a mechanical gauge to verify that it is an actual drop in pressure.

perhaps throw an extra quart of oil in the crankcase?

Thanks for the reply. I'm not sure the mechanical gauge it very much of an option, as it only happens while the car is being driven. And seeing as I literally JUST changed the oil, the level is right on the mark (double-checked). Not sure, but if I'm correct, the way the pressure sender and the bypass are arranged in the system, I believe if it bypasses it also bypasses the sender. So maybe a condition with the bypass?

Oil Pressure Senders are common. Replaced mine already. The only difference is mine pegged real high.

But common enough to need replaced after only a few days of service? Man I hope not.

Hmmm... That'* a good thought jwfirebird. Now that you mention it, if I recall correctly, I believe there was some oil in the connector when I changed it. Looked as if it might have ran down the back right side of the engine to the connector. I will look into that. Thanks!
