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.
It's not even worth trying. The pressure in the cylinders during compression will blow away any gasket sealant. The ONLY way is to remove the head, have it resurfaced then put it back together. NO IT WON'T only thing that will help is a new gasket set ( I KNOW DAMET )
none. if you use a gasket dont use sealant. Also never use sealant on a automatic trannsmission. It could damage the tranny and will not last.
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.
You will need a new head gasket if you see engine coolant in the oil. I don't know about the thermostat.
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.
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.
my head gasket was blown and it had water in the oil which made the oil look a milky color
