Ok, so I don’t know much about fixing trucks but I just got a 1996 Dodge Ram 1500 5.9 and trying to learn. I have a major oil leak and trying to figure out we’re it’s all coming from. The oil pan is soaked of oil but it also looks like it’s coming from above so the oils pan may be fine. The oil pressure sender unit seems to have oil at the base as well. I took a photo not sure what the pipe in the photo is but it’s not going to anything and wondering if oil is coming from that. See photo


In this one you can see the pipe I am talking about best.

I’m not sure but I think that’s the oil Pressure sender right above the pipe that looks wet as well

 

Unplug the oil pressure sensor. (yes, you are correct on where it's at. ) see if there is oil in the connector, if there is, replace it.

 

That piece of pipe is a transmission breather if I'm not mistaken. See where the hose that is connected to the tube, goes.

 

Thanks everyone I’ll try replacing the oil pressure sender and see if it fix the issue.

 

That tube is the transfer case breather
