Crank is out again...
John, I dont know of any cleaning solution in a hot tank that will eat iron. Rust, yes, but not freshly turned steel. We leave blocks in them for a week if they are real bad, and it doesnt hurt the exposed iron. Dont blame the sobriety..lol. The first trans I did with a friend who brought over cocktails while we worked..lol. Had a great time..trans didnt shift out of first, but we had a great time..lol. the drinks are for AFTER the car stuff now..lol.
