So I asked about this over on the truck section and got some peekers but not much help. I’m looking at buying a 2007 Chrysler Aspen (Dodge Durango) with a 4.7 with 123,000 miles. I’ve been out of the game for a while but I seem to remember something about the 4.7’s having oiling system problems. Is this true? What exactly were the problems? What steps can I take on a used truck to guard against possible problems? Thanks for any help.
