Need help removing Oil Fill Tube LS2

[RebekahsZ]

I am installing Holley plastic coil covers onto my LS2. I need to remove the oil fill tube in the valve cover. I can't get the darn thing off!!! It looks like it needs about a 1/2 turn counter clockwise, but it just sort of stops turning, then won't come out. If I look at the oil fill tube that came with the coil covers, there is a little plastic tongue clip that snaps up when you screw the oil fill tube in, but I can't figure out how to release that little tongue clip.

 

Please send recommendations.

Edit:

Went to LS1tech.com. Seems this is a universal problem. Now I've found 2 areas where the GM engineers goofed up. The first was the clutch bleeding system, and this is the second. You have to remove the passenger side valve cover (an area where the engineers totally rocked) and destroy the oil fill tube from inside out. This was not made to be removed. I was able to fish out several plastic chips that I had broken off trying to avoid removing the valve cover. Easy job, now that I've done it. Out of respect for the GM engineers, I managed to design my fuel system such that the fuel tank must be dropped from the car in order to service the fuel filter-not one of my better moments.
