Try cutting into the bolt with a cold chisel.This will make a groove to get a grip on by tapping the bolt to the left.work your way around tapping left until loose enoughthe grooves only need to be shallow,and of course dont miss the cold chisel and belt the timing cover.fixed the same problem last week this way.
