Many don't know that at your Porsche dealer you can purchase either just a filter element or a complete assembly consisting of the plastic container with (obviously) a new relief valve plus of course the filter element. Not a bad thing to do periodically.
Chris, the oil pressure relief valve is different from the filter bypass spring in the filter housing which you're talking about. Look at a diagram of the oil flow for 986 and you will see the relief valve at the level of the pump. It's a cap over spring assembly that Porsche updated, and the newer part helps improve oil flow during cold startups with high oil pressure (that's my understanding of it at least). Ttgator did a good video of the swap with part numbers (adds 5 min to your next oil change)
