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 range 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. This can't be by design. Does this binding go away when the cavity is pressurized? Was there a spacer that fell out when I removed the old hub? It's the same part number I took out, Volvo OEM 9497786: IPD and eEuro say it fits, FCP says it does not.
Anyone else experienced this?
