I don't see where it would hurt to try. I just don't know how well the penetrant will be able to seep past the seal and down and into the threads. Maybe if you let it soak for a couple days through a few engine temperature cycles. If you were already able to loosen them even a couple degrees, you might find it helps to tighten them just a very very tiny bit like only about 1/2" out at the end of the breaker bar, then loosen about the same amount. Work the breaker back and forth the tiniest bit until it loosens enough to start increasing the counterclockwise stroke.
