  1. Thank you for the response. Update- it ran fine for about 30 minutes. Oil pressure was at 30 psi on idle and 60 psi @1400 RPM. Suddenly the oil pressure dropped to 20 psi and then 0 psi and engine shut down again. So I'm back at where I started. Update- I got a code.. 1-1 oil pressure sensor fault. I'm going to change it out now.
  2. Help please, I just did a oil change as I normally do. I filled up my oil filters and all and then I cracked up the truck and noticed oil pressure dropping to zero on the gauge and immediately the Truck shuts down as I am in the cab. I noticed that my oil filters are extremely hot, I let the truck sit a little and changed the filters again... thinking that the filters may have been bad. Now I cranked the truck back up, everything seems to be running ok but still notice that the filters are really hot and oil pressure is at 25 psi. Which it would normally be around 50 psi in a cold start. What do you guys think this could be? Engine is a 2007 Mack Aset 427
