I finally got my tach seals and half-moon seals in the mail today and went about removing the valve cover so I could install them and the silicone Real Gasket I've been hanging on to (wanted to install them all at the same time).
So I go to pull the valve cover bolts out and two of them snapped. Then the screw holding the tach gear retainer snapped, leaving me with 2 rusted stuck screw shafts in the head and 1 in the valve cover. So off to the hardware store I go to get screw extractors.
When I get back I break the tip off an extractor in the valve cover. The extractor, of course, is super hard metal and I can't seem to drill through it. Is there a special kind of bit or something that'll cut through that thing??? Since that screw had obviously become thoroughly "one" with the valve cover I figure I might be able to just drill it out and tap the hole. But I have to be able to drill it first...
What's more, the extractors did NOT work in the head either so I've still got those stuck. And of course I also broke the tip off a punch I was pounding in one of the holes out of desperation. It's also super-hard metal. Again, these bolts have melded with the engine head so I figure I might be able to drill 'em out and tap 'em. It's just the valve cover, after all, so if I can manage some threads that'll hold enough torque to keep the gasket sealed, I'll be fine.
Please. Help. Me. I need some brilliant advice before I go insane!
