    35500 - Moroso Engine Seal is rated 3.8 out of 5 by 4.
    Rated 5 out of 5 by from Great product I used it on an E7 Mack with a cracked water jacket. If you follow the directions (especially the system flush) this stuff will seal most problems.

    Rated 4 out of 5 by from Ceramic seal Bought product 3 weeks ago. Good product. They don't tell you much on how to use. When you read instructions, very time consuming. Has worked good.

    In the product description it says "does not work with antifreeze", and then in the overview it says "run with antifreeze..." Which is it? What are the specific instructions? I want to use this for a Ford 300 straight six that likely has a cracked head.
