Carl, that is actually something I was going to do also. Pull out that seal, and probably add 1 washer to the hood to slightly lift it up.

As for fixing the real problem. I'm starting to get stumped here. Maybe refer to my other thread about this and let me know if you have any ideas. The one thing right now that I suppose it still could be, is a headgasket. But the car passed a compression and a leak down test, and a coolant system pressure test. I'd think that if anything was getting passed the headgasket, it would show in one of those tests. I don't see the problem as being the head lifting neither, because this is happening on the freeway when I'm in vacuum and not even seeing a max of 5psi at any point.
