Can use some advise please. During a broke a water pump bolt removal (6" O Clock postion) I have accidently drilled too deep. The hole for the bolt now extends into a what would apear to be a water jacket. I have put compressed air into the hole but it really seems to be a sealed. (No air comes out of the water pump inlets/oultes or oil filler tumb etc) Is anyone familiar with what is behind this bolt? Do I have to worry about any type of oil or water tryng to work it's way past the new bolt and heli coil that I will need to put in? Thanks Brian

 

Sorry, I can't help except to offer condolences. Sounds like something I'd do.
