Any known issues with head gaskets leaking, or heads cracking on these engines? Has coolant in the oil.

Was informed that the vehicle ran hot, cooling system was slightly low but didn't boil out, however did find coolant is leaking into the oil. Engine runs good, has plenty of power, drives fine. I'm just digging to see if this is a typical head gasket problem, or if I am looking at a cracked head or cracked block. Please let me know any information that you've got, thanks!

There are no bulletins regarding this I'm aware of. A compression test should tell you if it's a head gasket, cracked head, or a block.
