Can't Get Valve Cover Off - Help

[SmartSolution]

Got it! Thanks for the info.

A few weeks back when I did an initial inspection under the cover I noticed the breather hose insulation was torn. I'm guessing it's ok since the X5 runs fine and gets lots of highway miles. I'll just hope it's not too brittle and break when removing because I didn't order one. Whoever worked on it did a bad job. My leak seems to come from a prior leak around the eccentric sensor that was a patch job so I'm replacing the whole VC with a new one.
