On my 2007, there is a small cast alum cover on the side of the oil pan, right above the oil filter area. The cover is about 2.5" long, protrusion in the center, held on by two 10mm bolts and there is a gasket (mine leaking very slightly). Anyone know what the heck this cover is?? I checked AllData and it only said "Oil Pan Cover". Looking at the diagram, it looks like there are two ports under the cover. Maybe a connection point for oil heater, extra oil cooler?? Any ideas welcome.
