Review on Sierra International SR18 3851 18 3851 Gasket by Luke Right

This gasket was a huge disappointment. As my tests showed it failed to seal properly and caused leaks in my automotive engine .The material felt cheap and brittle, and was difficult to install. The only pro I can think of is that it was relatively inexpensive, but even then, I'd say it`s not worth wasting your money on a product that will only cause more problems down the line. Stick with a more reputable brand for your gasket needs..
