Saab: Sabb 1988 900 conv, blue devil, engine overhaul

Question
My sabb  turbo overheated I have it at the shop in San Antonio's euroasisan . They said I have antifreeze in my oil!!!! I want to put blue devil in it to seal the block just to get to running.  What do you think about those liquid tools for radiators ????

Answer
Bruce:
 Although most of the "block sealers" don't work, occasionally they do, thus saving many $$$!. So, I would try them all, one at a time knowing that the total investment will be far, far less than an engine overhaul.
         Good luck,
