2007 honda odyssey, 50000 miles. [1] last week, turn off engine, fan still running for 5 min. (overheating). Gauge not show overheat, no any lights on. [2] Check all fluids ok, except milky engine oil (no liquid oil). It is a sign, but I thought it is cold weather. [3] Sun. drove for shipping, heard squeeze sound, a bit smoke out from hood. Stop and found coolant overflow from reserve (some sticky brown coolant on floor). Added 3 qt. engine oil and saw oil over min on oil sticker. Added some coolant, not much, then drove 15 min to home. Noticed no heat now.

Milky oil can be due to not driving vehicle long enough for the engine to warm up??
There should be other things you could check before suspecting the head gasket or bent valve??

Most likely head gasket.

All signs lead to blown HG, no heat, overflowing reservoir, opaque oil. None of this sounds like bent valve.

the fact that there is oil in the coolant is a dead giveaway
