Im working on having my engine rebuilt, I initially had a different machine shop do my cylinder heads (new valve stem seals), clean/cut/inspect. Got them back, and was going to install them myself but pivoted and had the whole bottom end rebuilt also. The engine shop Im using is just starting to put things back together and they find this cracked lifter bore( driver side).
Has anyone seen this before?
What would cause that?
Are there any coolant passages behind/near this bore?
