I know the oil filter will be tight as heck to get off. I also have a 2008 mustang w/ the 4.6, so I have experience with these filters.
The Mustang has no oil drain plug gasket/crush washer. In doing a search for the torque settings for the drain plug I came across a drain plug gasket from Rockauto.comm. Does my Expy have a oil drain plug gasket/crush washer, or is it set up the same as the Mustangs plug?
My last 3 Fords have all had a rubber gasket that was part of the drain plug. None of them called for a gasket outside of that. As far as torque, I've always been a "snug it up and a pinch more" type guy with drain plugs. I can't even tell you how many hundreds or thousands I have done and I've never torqued one. No comebacks either.
