Tried the mallet, tried a razor knife, screwdriver, and putty knife. It is like it is glued on. I had gear driven cams installed by the dealer a couple of weeks ago. Didn't know of the spring then,,, dammit!!!

What about heating it or using liquid wrench around the gasket perimeter?

You should be able to pop it with a rubber mallet. You may have to hit it a few times in different areas.

Unless the dealer did something stupid and used some kind of sealant.
