One or all of these. Temperature goes up quickly. White smoke out the exhaust. With the engine cold take the radiator cap off and start the car. Water may shoot out the radiator a couple of feet high. Water in the oil, the oil will look like chocolate milk.
what are you asking here? PLease be more specific ...like - how do I know if my head gasket is blown, or what do I do about a blown head gasket ......
perform a pressure test on the cylinders. if they don't hold pressure it's a blown head gasket
There are several possible indications of a blown head gasket: If the head gasket is blown between adjacent cylinders there will be poor or no compression in either cylinder. Poor compression in any cylinder can be caused by a blown head gasket. That condition can also be caused by a burned valve or piston. Coolant in the crank case can be caused by a blown head gasket. Compression in the coolant can be caused by a blown head gasket. An engine with a blown head gasket usually loses performance and runs poorly or not at all.
my head gasket was blown and it had water in the oil which made the oil look a milky color
Because the head gasket is blown.
ckeck the oil dipstick if the oil has a color like chocolate milk the oil has water/colant in it which means the head gasket is blown and its leakin water into the engine block
Do a compression test.
Sure it will start with a blown head gasket. But, if you continue to run this engine with a blown head gasket you will destroy the engine.
No it will not. The only thing that will fix a blown head gasket is to replace the gasket.
Yes, I blown head gasket will definitely effect the emissions.
It does not matter. If one is blown on a V6 or V8 then you need to replace them both.
No, a normal tune up cannot cause a blown head gasket. A blown head gasket normally is caused by an engine overheating or by a defect in the gasket or head. If it happened right after a tune-up that is just a coincidence.
