I recall a guy who had a Beetle with the motor tilted to the left, ( running in a sand pit) he had tied to correct a bent frame horn by torch heating it with the engine still in and made it worse with a floor jack because he didn't understand the characteristics of annealing and tempering steel...metallurgy. I pulled the engine and trans reheated the frame horn and with a huge C clamp and 6' pipe realigned it then let it cool properly to return the hardness. Stuffed the engine back in and somehow it was straight on the first try.
