Foam coming out of oil breather

[deserth3]

Was looking for oil leaks this morning. As most of us know there is no PCV valve on the I-5 engine. Week when I took off the resonator, foam came out of the hole where the oil breather tube connects. There was also a layer of foam in the tube.
Is this normal, our do I have a blown gasket.

I have 165,000 miles on the truck. Oil was changed about 1k miles ago using Mobil 1 high milage.
Dealer changed head and about 21,000 miles.
I am loosing both coolant and oil. But I believe the coolant is water pump and/or radiator.

What's the oil look like on the dipstick?

Engine oil looks normal. Tranny fluid looks and smells normal. antifreeze looks and smells normal.

I think if the weather is cool enough to cause condensation and your normal driving is short trips that could be normal. If you don't make a lot of long trips and completely warm the engine condensation can build up. If the head is leaking I think there would be more water in it and you would see it in the oil.

Man, first fear is that is water causing the foamy emulsion. Play it safe and do an oil change with it cold and sitting for at least a day, lets the water separate from the oil and you will see it as soon as oil is drained. It only takes a few ounces of water to foam up a 1/2 gallon of oil. I know, I see it every day working in an oil refinery.
