The following is true for ANY head gasket failure.
The "best" head gasket sealer would be to remove the head, have it machined and put on a new head gasket.
Trust me; head gasket sealer won't do much good other than to lighten your wallet a bit.
There are always a few companies out there that will try to sell you something to solve your problem, even though it won't solve your problem.
The reasons the gasket sealer will not work are very simple:
1. the pressure inside the combustion chamber is so great that the sealing material is constantly being pushed away from the leak.
2. the temperature change causes expansion and contraction of the leak, so even if the sealing material COULD seal the leak, it would immediately break loose next time the engine heats up.
3. the high temperature of the combustion gasses cause the head gasket to continue to deteriorate and any sealing material that has built up will be immediately destroyed.
History of a typical head gasket failure.
The head gasket failed when the engine overheated. It may not show up immediately, but that's when the failure began.
If an engine is allowed to run when the coolant level is too low, the head will warp slightly. It isn't enough to notice when you look at it, but if the head gasket failed, the head is warped. The head gasket depends on even pressure between the head and the engine block. The pressure contains the high temperature exhaust gasses that are pushing against the head gasket every time the cylinder fires. When the head warps slightly, those exhaust gasses find a pinhole to sneak past. The hot gasses under high pressure then start to erode the gasket material and the head gasket will fail completely any time within a few thousand miles.
There really is only one way to repair it... sorry to be the bearer of bad news.
BTW, radiator sealer actually may work, but it's generally not considered to be a good "long term" solution.
