I had exactly the same thing happen to my 2001 2.7 Boxster, same ‘green’ hard rubber pieces in the filter, and like yours my car was running okay (at least I thought it was) and it wasn’t showing any fault codes. Also 2 of my 3 ‘Chain Tensioners’ were shot, and this combined with the ‘Variocam Tensioners’ being shot caused a rattle on start up, but again the car ‘seemed’ to be running fine. After replacing the ‘Variocam Tensioners’ and the 3 cam chain Tensioners, it was like a new car, instant increase in power and absolutely no rattle on start up ‘cold or hot’! I honestly believe that the ‘Variocam Tensioners’ and the ‘chain Tensioners’ are a bigger problem than the IMSB problem, when I pulled my motor to do the ‘Tensioners’ I did the IMSB at the same time (and it was in as new condition no wear at all). And yes the ‘Variocam Tensioners’ are expensive but mine did 150,000ks, before they became a problem, so when I compare that with my daily driver (Subaru Forester) and the cost of repairs on it, I don’t think the cost of fixing the Porsche is that bad. Let’s face it I know which car I’d rather drive.
