i am not familiar with the guardian system, but having been an aviation mechanic (helicopter) for 8 years, I know the effectiveness of a chip detector. it is mandatory on all the gearboxes and engines I worked on in the army. it saves lives and the equipment. also there was an extensive oil testing program for the detection of non ferrous metals. the fact there is an available chip detector, is a great preventative measure to avoid catastrophic engine failure. anyone who has a link to the various systems available, please post it. I am new to the Porsche community, but have been known to play with my toys, and push systems to failure once or twice before.

thanx,
