What I assume is this mod has been done to mine after it spat out the drive pulley bolt recently.
I didnt see the kit before fitting, but I know at minimum it comprises new bolt assembly ( hex head , not torx ) drive pulley and I think idler pulleys.

Also .... the replacement timing cover has the spacer cast in ( no washers !! ) , two forward facing slits just under the horizontal ridges on the front face , and a small gap at the bottom. All to increase airflow I guess. If I can get out to the car I will post a picture.
