Does the car overhead occasionally when the head gasket is blown or does it overhead constantly?

Answer 1

well, it could be cracked allowing small amounts of oil to get into the water which would let it get warm then the engine would start to miss or it could be as simple as a set of head gaskets

Answer 2

usually when a head gasket is blown an air bubble will form in the coolant. if the leak is small the air bubble will grow over time and cause poor coolant circulation and poor heat transfer. this can manifest itself in running hot or overheating occasionally with the need to top off coolant frequently. if the head gasket leak is more severe the vehicle can overheat constantly. even more severe case is when coolant and oil mix causing the coolant to look brown and engine oil to look like chocolate milk. the most severe head gasket leak occurs when engine compression is compromised which results in misfire(running rough or no running at all). this is usually a result of extreme overheating.

Answer 3

A head gasket does not always blow into a coolant passage. A compression check will verify a blown gasket. If yoyr oil is discolored you have a gasket blown into a coolant passage, park thr car immediately or ruin your engine. If your car feels as though it is misfiring it could be a head gasket. If your engine is overheating go to a radiator shop and get it checked. Don't start replacing parts till you know what is wrong.

Answer 4

constantly. the symptoms will vary somewhat depending on the car, and degree of severity of the break in the gasket. your symptoms can vary from erratic temp guage at times,overheating, no heat in the passenger area, to cant keep water in the system, to water filling up the cylinder, or oil pan, or water leaking externally, or steam out the exhaust. all of these COULD BE a head gasket issue. there may be other symptoms, but i just covered 99% of them right there.

Answer 5

if you mean overheat with a blown head gasket the frequency of it all depends on how long you drive a blown head head gasket will cause overheating if you are seeing signs of oil in the radiator or overflow tank that is a good indicator of such otherwise check the thermostat

Answer 6

Answer 7

In the early stages it could only overheat at times depending on the outside temp and driving conditions. It will get worse as time goes on and get to the point where it constantly overheats. By then some serious damage could be done. Get the car looked at soon.
