We bought this Fel Pro timing chain repair kit for our little 2.5L at our local auto parts store. In addition to the timing chain cover gaskets (which we didn't need), the kit included a new balancer seal, which we carefully tapped into the cover using a seal installer. You can use a regular hammer to install the seal if you're careful. The kit also included a steel repair sleeve for our balancer. You coat the balancer seal surface with the included Red Loctite and then carefully tap on the sleeve to create a smooth, unmarred seal surface.
