Frozen lower left alternator bolt

And nobody mentioned an air hammer.that would be my first step. With beating on it, the gaskets need replacing regardless what everyone thinks. A timing chain and gears too.
We are trying to save a 3 dollar bolt when it all should come apart anyway.
I just got a used 360 with mileage unknown. Water pump and a new timing chain without thinking twice. Sealant on threads and anti-sieze on the shanks. Clean all the threads.
