I recently purchased a gasket for my automotive engine and was disappointed with the results. According to my experience, the sealing capability was subpar and caused OIL leakage. The only pro was the ease of installation. However, the cons outweigh the pros. The gasket did not meet the high performance standards that I expected and had to be replaced soon after installation. i would not recommend this gasket for those seeking a reliable seal for their high-performance cars..
