Blue Devil (00209-6PK) Pour-N-Go Head Gasket Sealer - 16 Ounce, (Pack of 6)

I have tried and reordered literally every similar product on the market and find pour and go to work the best, for the least amount of money and with by far the least hassle. Locke the bottle says ' pour n go' . It has worked on 90% of what I tried it in including a Cadillac north star engine. I order the 6 pack. I have noticed in tough applications that a 2'nd treatment may be needed. I urge you to remember that you must find the source of what caused your engines overheating issues and to fix that first if you expect tangible permanent results from any product. If you have a small leak, a bad radiator or your fans are not working for example, your problems with the head gasket were caused by these failures. Fix the source of the overheating then fis the head gasket. In GM 3.1 and 3.4L engines, you typically have leaky upper and or lower intake gaskets that you maya not readily identify, you must first tear down the intake and replace the damaged gaskets before the product will seal the HEAD gaskets. Failure to do so will not get your car fixed. The intake job is exponentially easier and cheaper than a full head tear down, and must be completed to get results.
