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.
Cracked head or blown headgaskets
Blown headgaskets let water in, so you can see steam (white smoke) coming out your tailpaipe. You also should see water in your oil.
SEE DEXCOOL CLASSACTION SUIT" I would NOT use it.......$$$$. I HAVE SEEN THE GUNK & BLOWN HEADGASKETS................................$$$$$$$$$$
bad water pump, low coolant, blown headgaskets, if the car has been overheated, there is a good chance the head gaskets are blown
I was not aware that headgaskets were repairable. I have always replaced them with new gaskets. If you mean who replaces headgaskets, then that would be an engine mechanic.
I didnt know there was a bad way to be blown
Headgaskets most commonly blow due to the engine becoming too hot, this may mean a blocked radiator or a water leak causing the water level in the engine to drop.
Either low compression, coolant leakage externally or internally into combustion chambers causing white steam, or leaking internally and mixing with engine oil creating a creamy mess
Your answers will vary on this, however I do not consider a motor "blown" unless it has a hole in it caused by an explosion or internal malfunction such as a rod thrown through the engine block, or if it has over heated ( extreamly ) and warped the engine. if the engine is not fixable I say its blown. Some others will call it blown if just the headgaskets are blown or maybe if the engine jumped timing. These are fixable and even if an engine piston rod is broke but has not injured the block it also can be fixed. each Mechanic has their own opinion on what is called blown, some will call it blown just because they don't want to work on that model. Get a second opinion always !

if it sounds like garbage
when it doesnt work
Do a compression test.
It does not matter. If one is blown on a V6 or V8 then you need to replace them both.
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 ......
You know your car has blown a fuse if whatever the fuse is for suddenly quits working. For example if your radio is playing and for no reason quits it may be a fuse has blown.
Pull it out an look at it. Most of the time you can easily see it is blown. If not check it with an ohm meter.
By the large smile on its face.
Lack of compression
As with any car, low coolant will cause this car to overheat. Common areas of coolant lose are the water pump or intake manifold gaskets. If the coolant is full, then another common problem is blown headgaskets- especially the rear head. A blown headgasket introduced compression into the cooling system causing air pocket / bubbles. This will cause an overheat.- TechJK -----------------------------------------------------------
i don't know, why do you even need to know. Go to an expert!
U hear a pop in ur ears.....
Do a compression test.
If it has just left large amounts of motor oil, engine coolant and engine parts in the road, it is probably blown.
