Radrick Nice truck!! I just purchased mine two months ago with 148k miles bone stock and i would love to get it as nice as yours. What did you use for the pmd? did you use stock one with a just extend the harness or heath? Mine uses some oil and bill heath says it has to much blow by but it runs GREAT. The oil cooler is leaking and I'm not sure how much of the oil usage is from that. 01-31-2008
