Signs of a blown head gasket are. Overheating, oil level overfull, white smoke from the exhaust especially at start up, loss of coolant with no apparent leak, a gray or white foamy substance on the underside of the oil fill cap, air bubbles escaping from the radiator with the engine running, and possible engine miss.
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
my head gasket was blown and it had water in the oil which made the oil look a milky color
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.
Do a compression test.
It does not matter. If one is blown on a V6 or V8 then you need to replace them both.
i don't know, why do you even need to know. Go to an expert!
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
You pressure test the cooling system
Besides water in the oil, you will have little to no compression on the cylinder(s) in the area where the gasket is blown.
Because the head gasket is blown.
No it will not. The only thing that will fix a blown head gasket is to replace the gasket.
