Wah-wah. Scratched the camshaft replacing the seal. So much for stopping that leak. Much more luck with the intermediate and crank seals.

I can expect it to just leak, right? Or is it going to chew up the seal once she starts spinning?

    What were you using to remove the old seal that scratched the camshaft? In any case, when you scratch something that rides against a rubber seal, do your best to buff out the scratch, or at least remove any sharp edges with fine sand paper (600 grit, as much as you like, 400 grit okay, but don't go crazy and remove too much metal, and finish with 600 grit after) and cross your fingers. Unless the "scratch" is a gouge, you'll probably not shave too much time off the life of the seal.

      I was trying the "drywall screw" trick mentioned in the FAQ. Not really that great a trick, I'd not recommend it.

      Just deep enough to catch your finger nail. I hope that's not what you call a "gouge".

      I buffed it with some 1200; was concerned about taking off too much metal. I'll get a tiny bit more aggressive.

        I scratched my cam (with a drill-bit doing that stupid screw method >.< ).
        No leaks yet, that was about 4,000 miles ago. I managed to put the lip of the seal behind the scratch, but it is a bit worrisome. I wish I'd thought to buff it out then and there.
