Intake manifold leak?

Check your oil. If it's a milky color, you have a blown head gasket. If you are overheating AND missing and it's caused by the same thing, it's a head gasket and you're in the process of spinning a bearing if you don't check it out.

ours started out loosing water, no visible leaks, then it started missing, no visible leaks, then it started blowing the cap off the over flow tank, no visible leaks, then it started surging to the point that it almost would kill the engine. I ask on here, what could it be. Everyone said, pressure test, head gaskets. Couldn't be, no white smoke coming from the tail pipe. Then one day, everything really got worse, wouldn't even pull itself out the drive. No water in oil. I bite the bullet and remove the heads, sure enough, the gasket was blown dumping water into the cylinder with a clearly burned streak across the head gasket from the water passage to the cylinder.
I hope yours is not a head gasket but have it pressure test to find out before it gets worse.

As a general rule our engines will not get milky from a blow head gasket. If you where getting milky oil it would most likely be an intake or intake gasket. Yes intakes can go bad in the coolant if not maintained. The antifreeze can eat right thru the intake. Our engines do not have oil pressure going thru the heads so most of the time when a head gasket blows its from the cylinder to the the coolant. To get milky oil from a head gasket the coolant would have to blow out to the oil return hole. The coolant system simply does not have the pressure to blow out a hvy gasket that is crushed by cast iron. Possible Yes, Likely No. I would imagine it would take a defective head gasket or a major over heat to cause it.
In the video I posted the guy was worried about milky oil but with an over head cam like that you do have oil pressure going thru the head and the head itself is Aluminum. So the head gasket is seeing up tp 60 PSI of oil pressure (a lot more then the 16 PSI from coolant) For that car milky oil is a danger and a common problem.
