How can you tell if your car has a blown head gasket?
Depending on the severity of the leak, you may see bubbles in the overflow tank, indicating that the cylinder is leaking into the cooling system. Blue exhaust smoke could also indicate head gasket failure, but so could worn rings, valve stem seals or a faulty PCV system. Discolored fluids are more subtle signs of a blown head gasket.
Can a radiator leak cause a blown head gasket?
If a radiator hose suddenly blows off its water outlet, or the dipstick won’t stay put, this could be the reason. If a head gasket has failed between the water or oil passage and the outside of the engine, the result can be a simple coolant or oil leak. This is the least dire version of a blown head gasket, but still serious.
What causes a blown head gasket on a GM 4.3L?
You can find this tutorial in Spanish here: Cómo Probar Los Empaques De Las Cabezas (GM 4.3L, 5.0L, 5.7L) (at: autotecnico-online.com ). The most common cause of a blown head gasket is that the engine overheated because: 1) Fan clutch is not working, 2) All of the coolant leaked out of the engine and you kept driving it this way.
Which is a sign of a head gasket failure?
Cylinder misfire is another sign of head gasket failure, especially if the breach is between two cylinders on the same head. Cylinder compression and leakdown tests can localize the leak for scrutiny on disassembly.
Oil goes into the engine through the drain valve. When the head gasket blows, the car starts consuming a lot of oil. You may also want to check your pistons before concluding that the gasket is the cause. A whitish smoke being emitted by the car is the first sign of a blown head gasket. There is also a reduction in a car’s ability to remain idle.

What are the signs of a Northstar head gasket failure?
Here are the most common signs of head gasket failure on a Northstar: – Overheating – High pressure build-up in the coolant surge (fill) tank, that remains when the engine cools off – White smoke from the exhaust (condensation/water vapor is completely normal for any car) – Coolant smell from the exhaust
The bubbles are exhaust gases that force their way into the cooling system during the combustion process. An easy do-it-yourself test for a blown head gasket is to perform a chemical test using this type of tester on your coolant to check for the presence of exhaust gases to see if this is happening in your car.
How much does it cost to repair a blown head gasket?
Most of the cost of a head gasket repair is in the labor costs so the complexity of the job can change the cost significantly. For example, a “V” style engine has 2 heads and it is best to replace the gasket on both so the cost increases significantly over an inline engine.
What does the head gasket do in an engine?
The head gasket forms a seal between the engine block and the cylinder head. This means your head gasket has to seal both extremely hot, high-pressure combustion gases as well as engine coolant which can be anywhere from cold ambient temperatures to the normal operating temperature of your engine.
Can a head gasket leak cause white smoke?
If the leak in the head gasket is large this white smoke can often be excessive and billow from the tailpipe. Besides allowing coolant into the combustion chamber, an internal head gasket leak allows exhaust gases into the coolant.
