No, it will not. That is used as an emergency repair. The only fix for a blown head gasket is to replace it.
There are two kinds on their website. One that can be used while coolant is still in the vehicle (Head Gasket Fix), and one that requires all coolant to be drained before it is used (Head Gasket Repair). One may work better than the other.AnswerMay plug heater core I just used Bar's leaks block seal permanent head gasket fix 1 step (silver bottle 24 oz) $29.99 at O'reilley's , It worked excellent for 6 days on 1997 v-6 3.1 liter engine (it did not plug any heater lines)
Intake manifold may have moved when being tightened down causing intake gasket to move and not seal. There are water passages in it . I pulled the head and the gasket had moved, replaced the gasket and this time used permaseal this fixed the leak.
The head gasket is used to seal between the engine cylinder head and the engine block
A used head gasket is not worth anything, because it cannot be reused.
== == * If water is going out the exhaust, it might. If the radiator is being pressurized, it will not.* But Bar's Leak does not work!! It will further mess your problem up more. It is better to use a chemical called Thermaweld. (Note that Thermaweld's first Google result is about it being a rip off, and Bar's Leak makes more than one product. Some are for radiators and some are for head gaskets, and one is for cracked heads.)There are two kinds on their website.

You cannot and should not buy a used head gasket. If you have a blown head gasket you replace it with a new gasket. The gasket will cost very little. The labor to replace the gasket is where the cost is. Expect to pay from $500 to $1,000. This is a major repair that takes time.
You cannot repair a blown head gasket with Stop-Leak. The head will have to be remove and a new gasket installed. Do not drive this car as serious engine damage will occur. I agree 100%. The head will have to come off and re-fitted with a new head gasket, and possibly exhaust and inlet gaskets as these tend to break if you have to remove the manifolds. Having the head "machine-skimmed" is also wise as it will ensure a gas tight seal between the engine block,head and gasket.I'm afraid that there is no way around this, if there were a bodge that could be done, I'd probably know about it!
1. freeze plug in top of head under valve cover leaking. 2. head gasket leaking. 3. head warped causing head gasket to leak. 4. pin hole in cylinder wall ( caused by water hammer if pure water has been used in cooling system for extended period.)
I don't know of a permanent solution to a head gasket leak other than replacing the gasket. In emergencies, I have used the "aluminum dust" type of leak stopper, but it doesn't last very long. You need to replace it before major damage is done. ---- Bar's Leaks Head Gasket Fix for $29.99 or so is a good repair for this problem. Cadillac has a problem with leaking head gaskets in their aluminum engines, especially if the head gets warped due to overheating. I had a problem with the water pump leaking which was replaced at a radiator shop. Later, my alternator went bad, unrelated to the water pump problem, and seized, causing the belt to break under load, and breaking one of the pulleys as well. My engine overheated, warping the head. The radiator shop fixed the alternator, belt, and a tube that was rusty that went to the heater core, as well as the pulley that broke. I found out that there was a slow leak on the right hand side of the engine coming from the head gasket after I took it to Wal-Mart for an oil change and taking it back to the radiator shop to check for a leak in the hose they replaced. The radiator shop put 'core sure' into the radiator, but the leak persisted. Bar's Leaks Head Gasket Fix, a new product, that is compatible with antifreeze (unlike other products) seems to have worked within the first 15 minute treatment. I am not sure if it will last a year, though, which is my goal.
Never use sealant for a head gasket! It is used as a quick fix for cracks in the gasket but will not last very long. Safer to get the job done correctly.
There is none. You cannot fix a blown head gasket with any head gasket sealer of any brand. They should only be used in an emergency situation in order to get the vehicle to a repair shop. The only permanent fix is to replace the head gasket.
