Are you loosing coolant? Antifreez in oil looks yellowish and is very
slimy. Sounds like comdensation in the crankcase which the 4.7s seem to be
famous for. Many have found slime in the oil cap area. If it is really
cold where you drive and your truck is often driven short trips you may have
condensation in the oil. Unless you are running a supercharger I doubt you
have a head gasket problem.
