RE: Oil pressure dropping
My first thought, looking at the age, weight and hours... Overhead and replace the bearings in the lower end, along with pressurizing the motor to check for coolant in the liners. I would replace the oil pump too if you roll new bearings in. If still mandated, it could also be carbon packing, or a bad delete eating the motor alive. If you have not done an EGR tuneup on that motor, you should do that regardless, along with the overhead. I would also bake and de-ash the cans if they are still in operation... I am assuming this is a CM-871?
