    could be corrosion hole from water jacket. looks like metal mend to me so greys advice is good or you could get it tig welded. look at both costs.

    Thanks
    got a new one with the spare engine....any tips
    got the raidiator off , hoping i dont have to drop out engine.
    Also what is a good silicon sealent for the gasket.
    I did notice some small marks from the timing chain on the new rocker cover
    it`s all new to me
    will it matter?

    with it being the rocker cover a little automotive blue silicon can be used sparingly. many a motor has been killed with excess silicon strands.
