If you are only leaking coolant into the exhaust and use the type with copper in it, then yes, it should stop the leak. If coolant is getting into the oil or exhaust is getting into the radiator then no, none of them will do any good.
Yes, that is possible. A blown head gasket will destroy the engine.
It may work as an emergency temporary repair but the only permanent repair is to replace the head gasket.
In your dreams bubela! Buy a new gasket.
No.
Not likely.... I'd never use anything "temporary" on a head gasket.
Yes it does.
No. You need to remove the head(s) and have the head(s) checked for cracks and straightness, then install the head(s) with new head gaskets. Most head gasket manufactured are assembled dry, no sealants.
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.
IMO, this is only a temporary emergency fix. It will not permanently fix the problem. You will need a new head gasket.
It may work for a short period of time and should only be used as an emergency repair. The only permanent fix is to replace the head gasket.
No, it will not. This is just a temporary emergency repair. The only way to fix a blown head gasket is to replace it.
No, that is, at best, a temporary fix. The only permanent repair is to replace the gasket.
