Review on Blue Devil 00209 6PK Pour N Go Gasket by David Reyes

I have tried and re-ordered literally every similar product on the market and have found that I pour and work the best for the least amount of money and being the least so far Expenditure. The lock on the bottle says "Pour it up and go." It worked 90% of everything I tried, including the Cadillac North Star engine. I order 6 packs. I have found that under difficult conditions a second treatment may be required. I urge you to remember that if you want measurable lasting results from a product, you must find the source of your engine's overheating problems and fix them first. For example, whether you have a small leak, a bad radiator, or your fans aren't working, your head gasket problems were caused by these faults. Eliminate the source of overheating, and then the cylinder head gasket. On GM 3.1 and 3.4 liter engines you will typically have leaking upper and/or lower intake valve seals which you may not recognize immediately. You must first disassemble the inlet and replace the damaged seals before the product seals the HEAD seals. Otherwise your device will not be repaired. The recording work is exponentially easier and cheaper than removing the head entirely and must be done to get results.
