It is not uncommon for the intake manifold and/or valve cover gaskets to develop a coolant or oil leak. Leakage from the intake manifold may result in coolant in the engine oil. Coolant mixing with the engine oil severally impacts the lubrication ability of the oil. Internal engine may result if this condition is not repaired promptly.

I have oil in my coolant and my mustang runs very hot, I didn't know why but I've been told it's a head gasket that's blown or a cracked engine block.
