DD13 - No Oil Pressure

[deanwoda]

I have a 2015 114SD with A DD13 engine.
I have followed all the steps and still have no oil pressure. Just started all of a sudden. Replaced oring, pump, filter and oil pull the pressure switch out nothing out of the hole.
Anyone have this problem with there truck and get it fixed.
I have been to a Detroit shop and they are puzzled saying they have not seen this happen.
Any help would be appreciated.
Thanks

The two tube that run inside the oil pan have o rings on each end. Either the tubes have cracked or the orings on either end of them are allowing the pump to suck air. Detroit has put out a service bulletin on it.

I have replaced the o-rings and inspected the tube and pick assy.
I have oil to the oil filter but no pressure

Dumb question:

Have you checked this with a mechanical gauge? Or just going off the gauge in the dash?

I have manually tested and replaced oil pump sending unit O-rings, inspected tubes for cracks, inspected oil pick up manifold for cracks, replaced oil and filter, checked play in bearings. I can take the oil pressure switch out and no oil comes out of it with truck running.

Have you been doing regular oil samples?

Have you had one done since this current problem started?

How bout the bypass relief valve? Maybe stuck open? The stand pipe in the filter housing cracked?

Also oil filter drain back valve stuck open or fell out?
