My experience with Blue Devil: combustion leak into coolant, it did not work. When I called customer service to get a refund ( guaranteed to work or your money back ) they told me that their product rarely works on that type of leak. Since that product is guaranteed or you get your money back, there is little risk in trying.
Sorry I can't add to this thread but i do wonder . Did you get your refund?
