Hey y’all, first post here. I have a 6.4 that has possible died on me. I was on the way home the other day and at some point it decided to dump all the oil out from the bottom of the truck and seemed to stray it. The entire bottom of the truck at oil all over it, even my tail gate had oil on it. I was not aware of this till I came to a stop sign close to home and I started hearing a tapping/knocking sound coming from the motor. I nursed it home and haven’t moved it since. I noticed a small amount of oil on the ground after a day of it sitting. Checked the dip stick and it was bone dry. All the oil is gone. The oil seems to come from the passenger side of the motor. When running after a few minutes it starts the knocking/tapping. Does anyone know what this is???
