Some of the reasons why liquid aluminum is not recommended for head gasket repair are:
Ineffectiveness: Liquid aluminum is not able to withstand the high pressure and temperatures present in an engine combustion chamber. It is likely to fail when the engine is subjected to normal operating conditions.
Potential damage: Liquid aluminum can damage the cylinder head and block if it enters the cooling system or engine oil passages. This can lead to additional issues such as overheating and oil starvation.
Temporary fix: Even if liquid aluminum temporarily stops a head gasket leak, it is not a long-term solution. The repair will eventually fail and the leak will return.
Professional head gasket repair: Instead of using liquid aluminum, it is best to have a professional mechanic replace the damaged head gasket with a new one. This will ensure a proper and lasting repair.
