Easy enough job, right? Replacing the valve cover gasket has always been up there (IMHO) with changing the oil. Easy peasy.
So, In my desire to stop a potential source of a leak that's been plaguing my garage floor, decided to do this last night.... at around 10pm. Easy enough, move cables and hoses, and take the cover off. Cleaned up the head surface, cleaned up the cover. New grommets and gasket, and we're going back together. All of the bolts went back in easily enough. I'm tightening them all down, but the one on the very back of the head is giving me fits. I figure that I must have gotten some dirt into the hole, so I pressed on. It got progressively tighter and more difficult, but the grommet still spun freely. So in an effort to be done with this, I tightened it a little more, and broke the top of the bolt off.
So... Here's where It stands... the very back bolt broken off inside the head.. Nothing much to grab on to (if any) and poor access.
I'm pretty confident that I can't get it drilled, and still be able to get an easy out in. So my options are seemingly:
1: Try and drill/easy out the bolt on the vehicle. I am doubtful.
2: RTV film on both sides of the gasket near the back using some Right Stuff.
3: Pull the head, take it to a machine shop, and have them do the drill/easyout (possibly a helicoil ifall else fails).
Thoughts? Suggestions?
