If the engine is overheating and there’s engine oil mixed in the coolant reservoir, chances are the cylinder head may be cracked. A crack may form under the front and/or rear camshaft at the journals and is a rare occurrence.
You can see this crack from visual inspection. It causes engine oil to enter the cooling system and coolant to enter the engine lubrication system.
Replace the cylinder head if you find it’s cracked.
