I'd say give it some more time. I've heard stories of folks having to soak the cylinders weeks or even months to get some movement. Lots of different favorite concoctions around here....MMO, Kroil, ATF/ Acetone, etc.

Sort of doubt that this would stick the motor as tightly as yours is....but I guess you might try to get some penetrant down the lifter bores as well.
