I put on a Guardian when I first bought the car at 72,000 km (45,000 m). Picked it up on Kijiji from a guy in Calgary who never installed it on his 911. I have since done the IMS along with a full clutch job and I put the Guardian back on. I also change oil every 5000 km (3000 m) and cut open the filter running a magnet through it. This may sound like overkill but while I drive I have no thoughts of the bearing toasting my engine. I am now at 95,000 km (59,000 m). I knew when I bought the car that regular vigilant maintenance would not be cheap, but this is my baby and I plan on keeping her for a long time.
