Cody.... I have hunting boots older than you, but you sound like you have been into PDS like I would have like to do!!! I really appreciate the input on my oil leak, and has been great. I am Spartan tuned with the DOC, and DPF off. My warrantee is up in sept, and don't plan on renewing. I will be taking the cooler and EGR off then. I love the truck!! Pull like a mule. I don't want to but can afford if needed rebuild. I will be rerouting CCV and a better CAI, and maybe the cold air side of he CAC. I'm retired so would like to save money if possible? I know 6.4's aren't cheap. I also have some pretty good Ford Diesel Techs I can talk to. I just don't know how much I can talk to them about????? Unless I don't have a lot of leaks on driveway or garage I going to leave the major operation alone!
