With a gasket failure, the ONLY thing that is recommended by GM is replacement of headgasket - $2,500 to $4,000. Would anyone expect anything else to be recommended? duhhh !
the chemical "fixes" are meant to extend the life of a failed headgasket for a few more years - period. Dealer not required.
If the low cost "fix" (under $100) doesnt last, you are back where you started, junk the car, replace engine, tear engine down .. If the issue is the headgasket it works, if the issue is the head bolts pulled out, you ARE OUT OF LUCK ! How do you tell what the issue is? hmmm read our FAQ .. test for both.
SADLY, many of you are buying used cars that have had the "fix" performed and you will never know it. There is no way to track it, not even upon a engine tear down. those engines will pass the exhaust gas in the coolant and the compression tests .. .. its more common that you think, some of you have had your cars done by a shop and you dont even know it .. the "fix" is that successful.
Worst yet, if you think this is a GM problem, hang on .. IT IS NOT!
It is a global problem with modern aluminum engines of every make, including US, Japan, and European engines.
in this site, we simply choose to make it the big issue it is .. for reasons that escape me, most sites fear touching it.
