Do a compression test.
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
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
It does not matter. If one is blown on a V6 or V8 then you need to replace them both.
If you have a blown head gasket. you pour it in the radiator and it's suppose to fix your blown head gasket. I've never used it so i don't know if it actually works
They don't work and are only an emergency repair. If you have a blown head gasket the only way to repair it is to replace it.
You will not know until your remove the head. You have to remove the head in order to replace the gasket and once you have the head removed have it magna fluxed at a machine shop. That will reveal any cracks.
I have a 1990 Mustang 5.0. I know for a fact the head gasket is blown. Every time I open the radiator there is a release of pressure. So my answer is yes.
if you have water in the oil that's your problem.
If you remove the head then of course you replace the head gasket.Where can you get sodium silicate to fix a blown head gasket?Know that adding sodium silicate to an engine is only a temporary fix for a blown head gasket and will not permantly fix the problem. The only permanent fix is to replace the head gasket. I would never add any head gasket fix material to any engine.
