symptoms: Water/antifreeze in oil, external leak of antifreeze between head & engine block (this is where head gasket located) otherwise once while antifreeze come out of exhaust - they can leak a lot or a little - also if antifreeze keeps needing refilled & you cant find a leak easily is a good sign that head gasket leaks internally. Check oil dipstick, milky color in the oil or see water bubbles. Otherwise only true way is you see the gasket when heads are removed. big job. also need send heads out check for cracks etc

How can you tell if it is a bad thermostat or a head gasket?
Check for water in your oil, if so, this is a sign of bad head gasket. White smoke from the exhaust and loss of coolant with no apparent leak are all signs of a blown head gasket. You can also remove the thermostat (it is much cheaper to replace and easier to troubleshoot as well). If the temperature of the vehicle lowers, your thermostat was the problem.
How do you know if engine overheating has warped or cracked the heads or blown gasket?
