A breaker bar is your worst enemy on that particular piece. You're fighting against lock-tight and also attempting to not rotate the engine backwards while you loosen the bolt. An impact wrench or impact driver if you don't have air tools, is the only realy way to go. The popping action of those tools is what breaks the loctite barrier easily. Brute force will eventually prevail, but you're risking yourself (I had a chater bar pop loose and ding me in the forehead leaving me to see stars) and your bearing surfaces by possibly rotating it backwards.
