Jac Mac was right....
I think you called it cavitation.....you can see where coolant rusted the sleeve from the back until it got thin enough to allow pin holes. Holes appear larger here as the sleeve was bored out to remove it, thus opening up the holes
BTW - also found out I had a cracked rocker arm shaft in the process as well, which was close to causing big trouble. |
