Well I have not been able to look into this issue since the first post. And yes I am talking about the engine beds, sorry for the confusion!
In the photo below it is hard to see the cracks. They are at the base of the two blocks on the sides, and at the ends of the horizontal cross brace.
Two now useless layers of repairs were attempted, but they delaminated from the original stucture because the surface was not sanded first! Other than that, the repairs would have been good.
