    Removed inlet manifold to clean and saw this on the head

    is this a bad sign?
    i have seen 2 other pics in threads cleaning inlet manifold but the right hand side was only one looking like this in them
    is this coolant leak?
    and what are the ballbearing things in the head for?

    its just an area thats open, i assume the engine bay has been steam cleaned in the past and the water has sat in there till it steamed off

    That big is sealed in by the inlet manifold so water should not be able to get in there from outside

    Yeah but if you look at the pic, the corroded area is open to the elements where it extends up past the manifold/gasket, so Ste_Nova is right.

    Could be a non-return valve?
