Hi All Well, guys let me put my 2 cents in about what to use to free up an engine. I know this subject has been beaten up. I bought a 348 cu in Chevy engine that had been out in the rain and was locked up as much as I had ever seen so I asked my dad what to do. To make a long story short I used kerosene and automatic trans fluid mixed 50/50. After 2 weeks it turned over by putting a small pry bar in the started ring. Just another home remedy. Mackey |
