I was recently replacing my engine mounts. While I was replacing the passenger side mount, I sheared off the head of one of the two vertically oriented bolts that anchor the bracket to the engine block. I suspect that the bolt was cross-threaded when I had the belts replaced about four years ago. In any case, I have tried drilling out the broken bolt shaft to no avail. I have been told by a trustworthy mechanic that I need to replace the female threaded mount bracket, part #5. Has anyone done this? Is or as simple as removing three bolts and lifting the engine and replacing?
