I just bought a 08 6.4 with 135k. Had it about a week with no issues. went and did a oil change and noticed a drip of oil. After a long drive I got out of the truck and noticed oil everywhere on the truck. Checked the oil and i was 4 quarts low. Its blowing oil out of the truck somewhere on the passenger side but I cant find it. Its dripping pure clean oil out when I fill it and drive. Also as it sits up to a point. I've crawled under but a massive steel plate blocks me from seeing anything under the motor. Anyone seen this before?
