Sorry, it is a 3.5L engine.
Everything up above in the cooling system looks clean. I was wondering if a head gasket leak would end up in this area, or (after reading the forums this morning) if the water pump weep hole might be the issue.
Might have to invest in a small USB camera to have a look.
It is going into the dealer Monday for this and a bunch of other issues: Right axle Shaft leak, right inner tie rod sloppy, squeaky temp door actuators in the HVAC, possible right wheel bearing etc.
