sudden oil pressure drop

Driving home from work tonight heading down the highway at 60mph. I let off the pedal and oil pressure (dummy gauge) dropped to nothing. Truck never died after about 10sec it jumped right back up. Is it the sensor did my oil cool blow. Temps were normal range when parked. The oil pressure sensor is oily. Then anything I could be missing?

If the oil pressure switch is oily it is leaking. It takes almost nothing for oil to get in the lone pin and lose contact. You should look into replacing the switch and connector. Usually when the connector is contaminated it can still cause problems even after a new switch is installed

What about cleaning the connector with contact cleaner?

It seems to be a common problem on the 6.0.Mine does the same thing even after a brand new one was installed.Still trying to find the root of the problem and most likely it is a leak somewhere in the system cause my truck still has starting issues.If you replace it and it does the same thing then you know there is a problem elsewhere in the oil system.

Well it doesn't have any starting issues. And I never have to add oil between changes I have a small leak from my turbo drain tube have the new one just waiting on my oil cooler before I replace it. And it hasn't happened since then. So hoping it may have been a fluke thing.

My 05's been doing it for over a year now. I just haven't gotten around to fixing it.
