Anyone have an easy way to get that pesky exhaust manifold bolt off? The one thats on the very left hand side. I think its a 14mm bolt and there are brackets in the way.

 

Box wrench - put it on the nut, but UNDER the header. Drop a piece of rope through the header, and use it to pull the wrench. Repeat many times until it's loose enough to do by hand.

Also, please search next time. There's lot of threads about that nut.
