Default Over heated engine

A couple days ago my 242 turbo over heated and I have checked all symptoms for a head gasket being blown and the oil looks fine but when you start it it barely runs and stalls after 6 ish seconds with gas pedal on. and makes weird high pitches ”tss” noises under the hood every two or three seconds. There had been no leaks and the exhaust is not Smokey. And the oil pressure gauge bounces up and down. Anyone have any ideas to help me?

usual cause of overheating is lack of coolant. or lack of coolant circulation. IMHO, most common cause is a blown heater hose, or a broken water pump belt.

head gasket failures cause loss of compression, and/or intermingling of coolant and oil.
