Have a 621 bellhousing and everything looks great incl. the overspray from back of block but, and ain't it my luck, there appears to be a surface crack mebbee 1 to 1.5 inches in length near one of the bolt holes... Do I magnaflux the beast or will a simple water spraying test suffice?? I know the water can not simulate the torque that must go on in the various shift points, but, any opines?
Thanks!!! Ted
