"Crack"
and/or, he knows nothing about,
or the history of the 4.7
If it was your head gasget, it would run like crap, and show water in the oil.
You probably live in a cold climate, and probably take short trips.
I could go on with my predictions, but the advice above is right on.

Well Texas Todd, It must make you feel good to talk crap about people. Big man! I think we are all here to get and give advice and or an opinion. Although I am wrong in this instance It doesn't make my point invalid about coolant eating up bearings. Either way it should be addressed.

maxx,
No, it soesn't make me feel better. I should/could have worded it differently, my apologies.
And yes you're right, that COULD be big problems like a head gasket failure.
I live in a warm climate, and my average trip is over 20-30 mins., so I never see this stuff in my filler tube. I do use synthetic also, how synthetic?, Mobil 1, whatever it's now made of.

The oil emulsion is quite normal. I have only seen one head gasket failure with this engine and it was a ram truck with about 300 miles on it. The steel gasket was actually cracked which had to be a gasket flaw. The MLS gaskets are made to resist the "rubbing" of the dissimilar metals used in this engine (aluminum head to an iron block). This being said, if there is a constantly and quickly accumulating amount of foam, there could be other routes for coolant to enter the crankcase. The front cover being one. The seal on the front/timing cover seals both oil from leaking outside and coolant from leaking inside. If one of the rubber inserts on a coolant passage leaks, it will most likely leak into the engine. If this were the case, you would get a notable amount of water out of the drain plug while doing an oil change. The newer 4.7s don't have a front cover gasket at all and just use grey RTV to seal it. In all climates there will always be some moisture in the fill cap due to it being the coldest place on the engine. Just like the water droplets on a cold beer on hot day except the outside of the cold beer is now the inside of the oil filler. I own an 00 dakota and this bothers me too but just make sure to clean it and do your regular oil changes and all should be well. This oil emulsion is one of the reasons this engine is not friendly to those who extend oil change intervals and this does include synthetics of any brand. I am not hating on synthetic users either, I do use them in my turbocharged honda but not in my dakota as it is not needed. 3mo/3000 for the truck and all is well.
