VVT Plug bottoms out on Camshaft screw head ... S60 2007

Searched Forum, lots on SPARK plugs, but nothing (I could find) on VVT plugs.

After replacing exhaust VVT, I noticed the gear/hub was turning very rough, throughout its small angle of rotation ... an awful, metal-to-metal type of feel. Didn't seem right at all.

Knew I hadn't overtorqued the camshaft screw (88 ft-lb), but figured I'd better remove the hub. Took out the plug, and, lo-and-behold, the binding was gone. Put the plug back in, and ... binding again! The plug is actually bottoming out on the screw head. I can't believe this is by design. Does this binding go away when the cavity is pressurized? Was there a spacer that fell out when I removed the old one? It's the same part number I took out, Volvo OEM 9497786: IPD and eEuro say it fits, FCP says it does not.

Anyone experienced this?
