basically when the bearing needs to be replaced the valves will hit the pistons and the engine will stop. after that you will probably need to replace the engine. LNE sells a replacement bearing for around $600 check the site. Intermediate Shaft IMS Upgrade and Retrofit Kit for Porsche 911, Boxster, and Cayman models
Many folks replace good bearings to have peace of mind.
