Craig, That is the usual suspect in the photo. The speedy sleeve is usually stainless designed to slip over the groove after cleaning and using the supplied adhesive. Also, as mentioned above, clean all fasteners on the timing cover real good and then dope threads prior to putting back. Also, there may be two bolts which are accessed through the pan (ie pan may need to be pulled.) I'm away from home and going on memory. You will need to get a new seal of course for the cover, think all the stuff needed is in the small parts gasket set (except the speedy sleeve.) Many vendors carry the sleeve, I know Jim Carter does, or take your dampener with you to a bearing supply and they should have one on the shelf.
