You will notice the coolant reservoir level low with no signs of leakage, as the condition advances you may notice white, sweet smelling exhaust coming out the tail pipe and worse, engine coolant mixing with the engine oil.
I don't know which one was at fault but I replaced the head, the head gasket, and the intake manifold gasket.
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 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.
you will have antifreeze in your oil!
You may not see anything on the gasket. Usually a head gasket "blows" because of overheating that causes the head to warp. A gasket can be bad but there should be a visable break very often in the ring around the cylinder.
The four cylinder Fiero engine has a bad problem with cracking the cylinder head. If the gasket is bad it is likely the head will need an expensive repair. If the car has the V6 engine it is possible to just replace the gasket The real question is how good was the engine before the gasket failed? Should it be rebuilt or was it not burning oil and in good condition before the failure. Did the gasket failure cause any damage to the engine?
You will need a new head gasket if you see engine coolant in the oil. I don't know about the thermostat.
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.
perform a pressure test on the cylinders. if they don't hold pressure it's a blown head gasket
You will have to remove the head, inspect the gasket for breaks, check the head for flatness, and have a machine shop test the head.You will have to remove the head, inspect the gasket for breaks, check the head for flatness, and have a machine shop test the head.
my head gasket was blown and it had water in the oil which made the oil look a milky color
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.
