Where is the head gasket on an engine?
What is a Head Gasket? Located between the cylinder head and the engine block, you’ll find the head gasket. This small yet vital component is used to seal the internal combustion process allowing coolant and oil to travel throughout the engine to cool and lubricate. Which means, when it “blows,” it could spell big trouble for the engine.
What are the symptoms of a blown cylinder head gasket?

Engine Overheating – If the coolant is leaked into the oil, then it won’t be able to do its job properly of cooling down the engine’s components.
What kind of gasket do I need for a new cylinder head?
